Issue: VLC freezes Ubuntu 26.04 LTS OS while playing large playlist set to random daily. Mouse is unresponsive and have to press CTRL+ALT+DEL, sign out, sign in, and relaunch playlist to correct.

This is a PC being used in a video art installation in a gallery. It's a bit of a drive and I have to pay for parking each time I work on the PC as it is live in the gallery exhibition presently when we discovered the issue. The staff are kindly signing out and back in and relaunching it each time it freezes but they need me to fix it ASAP.

System Specs:

• i7-4770
• 8GB RAM
• Older 4TB hard drive I've formatted and added the media to
• Hardware tests passed.
• Disabled Power Saver mode for the exhibition so it wouldn't go to sleep during gallery hours.
• DisplayPort to HDMI cable connected to HDMI to RCA Converter plugged into a 1990s Samsung television set as part of the art installation.

The video content comprises old 80s cartoons and Saturday morning commercials which display on the CRT. The files are modest in size and low to medium resolution but it is a very large playlist, (about 60 days of continuous content). No HD content. VLC is set to play the playlist with random mode enabled. I also set it to expand all subfolders by default for the playlist.

The PC was freshly formatted with a bootable Ubuntu flash drive and the latest stable OS version installed.

All of the media content was transferred using FreeFileSync to verify data integrity to a folder on the PCs desktop. A playlist was generated of the folder's content which is what we launch in VLC each exhibition day.

The playlist runs day and night and we power off the CRT after hours to preserve its life. There is a small standard monitor connected which is set to mirror to the CRT.

I configured VLC to ignore all non-video file formats so that miscellaneous content from the folder wouldn't present an issue when I generated the playlist.

No other applications were installed and no other changes were made to the freshly-formatted PC other than the aforementioned media folder.

I read that VLC doesn't generate a log file by default. I've tried to provide all available information to expedite a resolution.

I searched the Ubuntu section of the VLC support forum for "freeze" and couldn't find a solution.

I posted the above to the VLC forum and the reply I received stated: "VLC can't freeze the whole OS, only itself. Looks like your display server is what is crashing. Update it or use another one."

I believe I'm running Wayland (the default), and I stated that I performed a fresh install of the latest stable version of Ubuntu so I would be inclined to think that I'm already using the latest version of the best display server.

I hope to not have to migrate the playlist to another video application as I mentioned I already configured VLC to ignore a whole list of non-video file types which occupy the collection folder/subfolders. And I am fairly competent with VLC vs learning an entire new application for the art exhibit which may introduce new issues. Staying with VLC is ideal.

I'm posting to the Ubuntu support forum as the VLC community said VLC can't freeze the OS so it's likely a video server issue. Can someone provide specific steps for me to resolve the freezing issue?

Thanks for any help you can provide!

Recently, on this Dell Latitude 7380, running Ubuntu 24.04.4 LTS with Wayland, the kernel updated from v. 6.17.0-40-generic to 7.0.0-28-generic. After rebooting the display became extremely dark, starting immediately after the selection of OS was made in grub. It was barely readable in a dimly lit room, and it also appeared to flicker slightly.

Rebooting and selecting kernel 6.17.0-40 from grub worked normally, with fully controllable brightness. Retesting both kernels gave consistent results. For now, I've changed the grub selection order so that 6.17.0-40 is the first, i.e., default entry. However, I'd like to know what causes the issue, and if there is a workaround, or newer kernel in the pipeline that could be tested to see if the issue has been resolved.

The results of uname -a are as follows for the new and old kernels, respectively:

Linux <PC_NAME> 7.0.0-28-generic #28~24.04.1-Ubuntu SMP PREEMPT_DYNAMIC Wed Jul  1 15:50:57 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

Linux <PC_NAME> 6.17.0-40-generic #40~24.04.1-Ubuntu SMP PREEMPT_DYNAMIC Tue Jun 23 16:48:12 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

Here are relevant parts of a system report:

Has kernel 7.0.0-28-generic dropped support for hardware in this older Dell?

Is there a conflict with Wayland windowing system?

Is there a driver needed?

Any help would be appreciated.

This issue is about the Linux kernel update. Nothing in BIOS has changed.

Is this a legit Linux update: Firmware update available for UEFI dbx. UEFI dbx can be upgraded from version 20241101 to 20260402

Ubuntu 24.04 up to date

Gthumb 3.12.10

All of Gthumb's functions work properly but printing.

It was printing a while back. Don't know how long ago, but not long, a few weeks maybe.

Updated the system as usual, 1 or 2 times.

Now Gthumb crashes when I try to print a jpg. Never has before.

I uninstalled it, reinstalled it and did the same with the printer, a Brother MFC-2710DW.

The printer works as expected from other apps, including GNome Image Viewer 45.3.

I don't really know what to do here.

This is different from How to install software or upgrade from an old unsupported release? since I have already changed my repos to old-releases.ubuntu.com and done everything else from that issue.

Here is the ultimate failure (all the prep-work is below). Note: I mangled the protocol on the URLS to bypass the spam detector (http:// --> http-)

Any thoughts?

OSK keeps popping up in clamshell mode on my Dell 2-in-1 laptop. So then I do Settings > Accessibility > Typing > Screen Keyboard > toggle off, and that persists across that session and even a restart, but the next day, the setting has flipped back to on! Block Caribou didn't work for me. This issue happens when I'm in clamshell mode and clicking into text boxes in certain apps, such as Terminal, Files, Settings, or Thunderbird, but not Bitwarden or VSCode. It also happens on the login screen.

Some commands I've ran:

• gsettings get org.gnome.desktop.a11y.applications screen-keyboard-enabled → true (when the issue is present)
• gsettings set org.gnome.desktop.a11y.applications screen-keyboard-enabled false (then I checked the setting again and it was false, but still reverted later)
• cat /sys/class/dmi/id/chassis_type → 31
• cat /proc/acpi/button/lid/LID0/state → state: closed
• grep -r "screen-keyboard" /etc/dconf/ → no output

Could someone please help me disable the OSK until I want to use it? Thanks so much!

I was installing Ubuntu Desktop 26.04 onto my drive when an error came up saying something went wrong but it didn't know what. The logs showed errors like grub-install: warning: efivarfs_set_variable: writing to fd 9 failed: Cannot allocate memory.

My laptop is an Asus x1404za with 8GB of RAM, 128 GB of storage, and a 12th gen Intel Core i3. I've added an ax210 to it for my previous Linux installation.

I believe I have done everything right, although I am new to Linux.

I frequently experience hotspot and ethernet connection problems on my Ubuntu OS, sometimes, it connects successfully but I can not access anything on the internet whiles at the same time, with the same hotspot, I can connect with my Windows OS and it works. I am using Ubuntu version 26.04.

I have an Ubuntu LAMP server and its server certificate is almost out of date. We managed to create a new server certificate and put it here:

• /etc/ssl/certs/CERTNEW.crt

• /etc/ssl/private/CERTNEW.key

Because we also have a new issuing server, we also have new CA root certificate that we put here:

• /etc/ssl/certs/CA.crt

Within /etc/apache2/sites-available I see a few vhost *.conf files which have a link to the current server certificate. Before I continue further I would like to know which steps I need to take now (2 questions).

1. Which exact files do I have to modify to point to the new server and CA certificate?

2. Where do I put the intermediate certificate?

I was trying to organize my Panel, and accidentally deleted the battery percentage indicator. How do I fix it!?

I have a small server (Zotac ZBOX-AD06-U) running Ubuntu 24.04. Twice now it's had an entire series of corrupted files on the HDD. (This time it's affected apt such that apt --fix-broken install fails; I think a reinstall will be required regardless.) It'll hang at boot complaining that a manual fsck is needed, then give errors like "inode <inode id> seems to contain garbage". The SMART diagnostics aren't finding anything wrong.

1. How can I tell if there's a hard drive problem doing this? What other troubleshooting can I do to try to narrow it down?

2. What can I do to prevent it in the future?

SMART data is below. The short and long tests at 156xx hours was after this event, and I believe the two tests at the 86xx mark were last time this happened. (No telling how long it had inode errors between these two. It is very rarely rebooted.)

I'm running a Dell Optiplex with integrated intel video card. I recently upgraded from a live USB, wiping the root directory, but kept my home directory in place.

Since upgrading to 26.04, I can hear my fan rev up any time my browser tries to load a page with a lot of images. Like Amazon or Ebay, where there's an array of images on a page. I don't know if it's this or the Javascript, but it takes a long time to load and I can hear the fan always revving up.

Mouse performance becomes choppy over time. I'm running dual monitors, the first with Displayport and second with HDMI and when I move the cursor from the first to the second, I can see it stutter.

In general, I'm just getting laggy performance and it feels like a video card-related issue. Has anyone been having these problems, and how do you fix them?

I'm upgrading from the last LTS release (24.04). Prior kernel was 6.17 and the new one is 7.0.0. Graphics specs are below:

I'm trying to install the Ubuntu Server operating system, but unfortunately at the last stage of installing, the installation logs, the 'Reboot now' button is not showing up. I've waited for fifteen minutes. It is an older laptop (Dell Inspiron 15 5000 series i7. I'm pretty inexperienced with this kind of thing. Is it just slow or is there something wrong? Also, my Ethernet connection is not working properly. I don't know if this has something to do with it.

I also can't backtrack by pressing the Esc key or a 'back' option. The version I am using is "ubuntu-26.04-live-server-amd64".

I use an Asus E510 laptop. After upgrading from Ubuntu 22.04 to Ubuntu 24.04 the left audio channel is now shared across both speakers on the output device (my TV) and the right channel audio signal is not sent.

Clean booting into Ubuntu 24.04 or Ubuntu 26.04 from a live disk also causes the problem, so it is not a problem caused by a damaged or jumbled upgrade. Clean booting back into Ubuntu 22.04 from a live disk fixes the problem again, so it is not a setting on my TV nor is there anything wrong with my laptop or HDMI cable. I have also tested with multiple HDMI cables to be sure.

There are also issues with the new 5.1 and 7.1 HDMI output modes in Ubuntu 24.04 and onward where the right side channels do not respond appropriately.

This is an untenable situation.

I am getting the apparently common problem of a boot partition with 0 space left. I have gone through the best links that I found so far, but with no luck resolving it (partly because I'm a noob).

How do I free up more space in /boot?

The autoremove command does not work because it needs to create files, but there is no space left to do so.

The sudo apt-get purge command also fails due to an attempt to create files again was met with no space left.

The boot partition is 2GB and attempting to expand partition doesn't work (using Disk Utility) because there is no non-filesystem free space left on the 2TB drive.

EDIT: Below is contents of the /boot folder, then the result of "df -h". I am on "Ubuntu 26.04 LTS - Framework desktop". Is it safe to manually delete files listed as 7.0.0-15 (old kernels?) via "sudo rm" instead of "purge" which does not work (requires space)

ls -1 df -h

For starters, here is my system. EDIT: My headphones are Skullcandy ANC Crusher 2, if that also helps.

It started when trying to fix a connection issue between KDE Connect and my Android. I changed my firewall settings to "allow" and while it fixed the KDE Connect issue, it caused my bluetooth audio to sound choppy and distorted in A2DP sink.

I then tried a few fixes for that from here and here and here.

And now bluetooth has disappeared from my system tray entirely, with no way to reconnect it.

Running hciconfig shows this:

Trying to bring hci1 back up using sudo hciconfig -a hci1 up only results in a timeout error.

Not sure what I'm missing here. I tried some instructions to also reinstall the entire bluetooth stack with no luck either. Any ideas would be greatly appreciated.

UPDATE: Apparently I can still connect my headphones using bluetoothctl using the scan command to get the MAC address of the headphones and then forcing it to pair. Audio is still choppy but now I'm wondering what is really going on. Perhaps it's just an issue with the system tray itself? Bluetooth apparently does work, but it's a pain to do it this way every time.

UPDATE 2: I'm not sure if this is anything but using hcitool dev shows this:

dorkus@Robot-Overlord-2:~$ hcitool dev
Devices:
        hci1    74:F6:1C:14:86:DF
        hci0    C8:94:02:6E:C8:B4

Afaik, my PC only has one bluetooth receiver. So I wonder why it's showing 2 of them. I got the Bluez menu to come up in the system tray and it shows both as well. But only hci0 seems to work, possibly being the actual bluetooth hardware.

I’m having a Wi-Fi issue on my ASUS Vivobook (X1504ZA) running Ubuntu 26.04 LTS. I don’t really know much about this kind of Linux/driver/network stuff, so I’ve been trying to figure it out step by step.

Hardware info

My Wi-Fi card shows up as:

• MediaTek MT7902 802.11ax (Filogic 310)

• PCI ID: 14c3:7902

What works

• Internet works fine using USB tethering from my phone

• System is updated (kernel: 7.0.0-22-generic)

• Everything else on the system seems normal

What doesn’t work

• No Wi-Fi option appears in network settings

• nmcli shows no Wi-Fi device at all

• The Wi-Fi hardware is detected by the system but marked as UNCLAIMED

• The mt7921e driver loads, but it does not attach to this device

What I found (with help)

I honestly don’t know much about drivers or kernel stuff, so I used an AI assistant to help me troubleshoot step by step. We checked logs, drivers, and kernel modules together.

From what we found:

• The Linux mt76 / mt792x drivers are installed

• But they don’t seem to support my exact chip (14c3:7902)

• So the system detects the hardware, but no driver actually connects to it

Current situation

It looks like the Wi-Fi chip is not supported (or not fully supported yet) in my current Linux setup.

Workaround

I’m currently just using USB tethering from my phone, which works fine for internet.

Why I’m posting

Since I don’t really understand this technical stuff deeply, I thought I’d ask here in case someone knows a fix, patch, or workaround for this specific Wi-Fi chip.

Any help would be really appreciated 🙏 Should i install windows now?

I installed Ubuntu 24.04 on my Asus Vivobook M1502YA (Ryzen 7 7000 series), but the Wi-Fi doesn’t work at all.

Details:

• Wi-Fi chip: MediaTek MT7902 (lspci shows 01:00.0 Network controller: MEDIATEK Corp. Device 7902)

• Kernel: 6.17.0-20-generic (uname -r)

• What I tried:

  • Upgraded to latest kernel using Mainline

  • Installed linux-firmware

  • Ran sudo ubuntu-drivers autoinstall

  • Checked rfkill (no soft/hard block)

Output:

ip a
# shows only:
1: lo: <LOOPBACK,UP,LOWER_UP> ...
2: enx... (USB tethering interface)
# No wlan0 or wlp interface detected

Problem:
Wi-Fi interface is not detected. USB tethering works, so internet is fine.

Question:

• Is MediaTek MT7902 supported on Ubuntu yet?

• Any workarounds or experimental drivers to get it working?

Thanks in advance!

I am encountering a persistent shutdown issue that seems to be specific to Ubuntu, and I would like help diagnosing it.

System Information:

   Hardware: Lenovo ThinkPad P50s
   Architecture: x86_64
   Boot mode: UEFI
   Storage: Internal SSD (issue also occurs with no external devices connected)

Affected Ubuntu Versions:

   Ubuntu 24.04 LTS
   Ubuntu 25.04

This issue occurs on both versions.

Other Operating Systems (for comparison):

   Windows (same machine) → shuts down normally
   Kali Linux (same machine) → shuts down normally

This suggests the problem is not hardware-related, but likely related to Ubuntu-specific kernel, systemd, ACPI, or power management behavior.

Problem Description:

   When selecting Shut Down in Ubuntu
   The shutdown process starts
   The screen may go black or stay on a shutdown screen, however the system never fully powers off.
   Power LED remains on, and sometimes fans keep running. The only way to turn the machine off is by holding down the power button.

Steps to reproduce:

   Boot into Ubuntu (24.04 or 25.04).
   Use the system normally (or even stay idle).
   Click “Shut Down” from the system menu.
   The system hangs and does not power off.

What works:

   Reboot usually works correctly.
   Shutdown works normally on Windows and Kali Linux.

What I have tried:

   Waiting several minutes during shutdown
   Disconnecting all USB / external drives
   Fully updating the system
   Checking dmesg and journalctl for errors

Expected Behavior:

   The system should power off completely after shutdown.

Actual Behavior:

   Shutdown hangs and requires a forced power-off.

Suspicions / Questions:

   Possible ACPI or power-off (poweroff.target) issue
   Ubuntu-specific kernel or systemd configuration
   Missing or incompatible kernel parameters for ThinkPad P50s

I would appreciate advice on:

   What logs or debug options to collect
   Kernel parameters (e.g. acpi=, reboot=) worth testing
   Whether this is a known issue with recent Ubuntu kernels

I have a new ASUS Vivobook X1404ZA laptop. I installed Ubuntu, but the Wi-Fi and Bluetooth are not working. The Wi-Fi icon doesn't show any networks, and Bluetooth seems to be missing. Here is my technical information: --- **

1. My Wi-Fi/Network Controller:** (Output of `lspci -nn | grep -i network`)

03:00.0 Network controller [0280]: MEDIATEK Corp. Device [14c3:7902]

---

**2. My Kernel Version:**

6.17.7-061707-generic

---

**3. My Kernel Log (dmesg):**

(Output of `sudo dmesg | grep -iE 'mt79|7902'`)

[ 0.276113] pci 0000:03:00.0: [14c3:7902] type 00 class 0x028000 PCIe Endpoint

[ 221.622095] mt7921e: unknown parameter 'disable_usb_sg' ignored

*(Note: My `dmesg` also shows many `mt7921e` errors, but this seems to be the wrong driver for my [14c3:7902] hardware).*

---

**4. RFKill Status:**

(Output of `rfkill list`)

0: hci0: Bluetooth

Soft blocked: no

Hard blocked: no

*(As you can see, `rfkill` only detects Bluetooth, not the Wi-Fi device, confirming the kernel is not loading the Wi-Fi driver).*

---

What is the correct driver for the MediaTek MT7902? I tried loading `mt7925e` but it didn't seem to work. How can I get this hardware enabled?

Thank you.

I have an ARM-based virtual machine running Ubuntu 24.04 LTS (GNU/Linux 6.8.0-40-generic aarch64) at a small cloud provider. Today I was not able to install a new package; apt update and apt upgrade failed and gave errors about missing packages.

I tried several mirrors, but they are all missing some packages for Arm64. While manually checking a mirror from my browser, I noticed that all the other folders have a modification date of today.

Why are the Arm64 packages missing? Are they being built as I type this question? When will they be available?

The end of the output of sudo apt update:

In short: how I can I use the Plasma desktop environment over VNC?

I am running Ubuntu 22.04.3 LTS with KDE Plasma 5.24.7 (the "Kubuntu" image install).

Logging in to the machine physically is fine and the UI looks awesome. Now I want to access the machine using something like remote desktop, I figured VNC is the best option.

So I install and run tightvncserver on the machine, basically following this guide:

sudo apt install tightvncserver
tightvncserver :1

I can already remote in now, from Windows, using the RealVNC client. However, the screen is just empty.

So I go back to my machine to change ~/.vnc/xstartup and make it look like:

#!/bin/bash
xrdb $HOME/.Xresources
startxfce4 &

After restarting the VNC server I can now remote in and actually see and use a desktop, but the environment is of course now Xfce, instead of KDE Plasma like I use with physical access.
How can I use KDE when using VNC? Which xstartup command would I need?

I have already tried startkde &, startx & and startplasma-x11 & but all of those just result in a plain grey screen.

Specifically I found this guide which suggests the following for xstartup:

#!/bin/sh
# Start up the standard system desktop
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
/usr/bin/cinnamon-session
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
x-window-manager &

Now I get the Plasma loading splash screen on VNC connect, but after a few seconds the screen becomes black. The full error log for this from TightVNC:

If I start Ubuntu from a cold boot, Internal audio, and Headphones work flawlessly.

But if I start Windows and I reboot to Ubuntu, only internal speakers work, no matter how much I connect and disconnect it from my laptop, the audio comes out of the speakers and not through the headphones even when they are connected.

Here are my logs and dumps:

Can it be a kernel-related bug about this?

I really appreciate any help you can provide.

Node.js is installed but not working. How to solve it?

I am using Ubuntu 20.04 with kde plasma. All of a sudden, my Dolphin file browser takes forever to open. Earlier it opened instantly, but now it is taking almost 30 seconds to start.

This seems to have started after an update; when I use kernel 5.11.0-38-generic there is no issue: the problem occurs when I use kernel 5.11.0-41-generic. In addition when on 5.41 the whole system seems to run slower.

When I run dolphin from the command line, there is no error output, and it is as slow as before to open.

I am using an Intel 4690k CPU with 16GB ram and SSD. I checked my drive health and it is fine.

I bought a CSR 4.0 bluetooth toogle hopping to use for music and stuff. I have already tried a plug n' play BT toogle but I can't remember its brand or model (it was white though). It worked for 4.0 devices but not for my 5.0 headphone for instance.

When I did the same thing for this "plug n' play" usb toogle it didn't work. After search the web and countless forums I come here again asking for help. Here is a quick list of thinks I tried and some details of the issue:

1. First I installed the bluez and blueman packages (through synaptic) both in dev versions as well. When I open it and try to pair with my phone, it keeps searching endlessly.

2. Also while blueman tries to search, the bluetooth system tool does as well.

3. However, after installing the packages, my desktop is recognizable by my phone. But when I try to pair them: an error mensage apears.

That was pretty much what I did to solve it. The rest was me trying to diagnose the problem. It follows:

And:

Finally I saw that tip in one askubuntu topic and tried my own. The result:

$ sudo hcidump

< HCI Command: Reset (0x03|0x0003) plen 0

As a result of the code from another terminal tab

$ sudo hciconfig hci0 down
$ sudo hciconfig hci0 up
Can't init device hci0: Connection timed out (110)

So long I've seen, $ sudo hciconfig hci0 reset also works. Then the bluetooth system manager and gnome control panel behave like this and I have to remove and insert the device to be connected again.

Finally, I read that this could happen as the kernel were updated from Ubuntu 16 to 20. Mine is 5.8.0-43-generic, but people complain about this problem since 5.4. I'm not sure if installing an old kernel would solve it once I know almost nothing about it.

Any help is welcome ;)

Whenever I boot up, my monitor's settings are always zoomed in about at 10, out of a scale of 0-100.

It also happens if I turn my monitor off and on again.

If I change my Display settings to rotate my screen orientation from Landscape to Portrait and back, but not Landscape to Flipped Landscape and back.

And changing the Scale in the Display Settings menu doesn't mess up the Zoom again, either.

I have a Dell SP2208WFP, and my Monitors.xml looks like:

<monitors version="2">
  <configuration>
    <logicalmonitor>
      <x>0</x>
      <y>0</y>
      <scale>0</scale>
      <primary>yes</primary>
      <monitor>
        <monitorspec>
          <connector>HDMI-A-1</connector>
          <vendor>DEL</vendor>
          <product>SP2208WFP</product>
          <serial>RR268831CT0U</serial>
        </monitorspec>
        <mode>
          <width>1680</width>
          <height>1050</height>
          <rate>59.954250335693359</rate>
        </mode>
      </monitor>
    </logicalmonitor>
  </configuration>
</monitors>

...

And now, Scale is reset to 1... Because I exited a fullscreen app or something??

...

It even happens in Recovery Mode, when I don't have a DISPLAY variable set.

...

But, it doesn't seem to happen if I connect through VGA instead of HDMI...

Still happens in 26.04 Ubuntu Desktop, Doesn't happen on my Windows 10 machine, and zoom level changes accordingly when I between them using a UGreen HDMI splitter (ACBUGN50966).

Doesn't happen on a boot, until after the spinny icon / booting screen refreshes. Not sure what the refreshing indicates, but something?

Every time I download a game from the terminal I can't open it.

I just installed Ubuntu on a new machine and everything seemed to be going fine. I and a coworker were having some issues with a few things and have managed to lock-out a local admin (sudo?) account after unjoining an AD domain using realm while troubleshooting some McAfee issues were were having. I'm 99.9% certain that the password has not changed for the user. I have followed ALL the steps found here for resetting the password as root in recovery. When I try to run

sudo passwd USERNAME

I get the error:

root@hostname:~# sudo passwd USERNAME passwd:Permission denied passwd:password unchanged root@hostname:~#

When I try to do the steps for the "The Drastic Measures", I notice that the shadow file does not show what would usually indicate an encrypted password for the user. Instead it looks like:

username:!:14920:0:99999:7:::

I have removed the exclamation point and still have issues. Even when I run

passwd

as root through recovery, I get a permissions denied error. As it stands right now, I can only log into the machine as root through recovery. I'm at a complete loss at this point and trying to avoid breaking down the machine and starting from scratch. Any help you guys can provide would be greatly appreciated.

I got MS word document, person asked me to edit it, to add table of contents, to add page numbers, because she doesn't know how to do in MS Office. So I did with LibreOffice writer. But when I saved (tried several filetypes, including: .doc, .docx, .odt) and send file back to her through facebook firefox and chrome showed error in download list saying

"Blocked: May contain a virus or spyware - "

And actually it says same thing when I download file which I sent and try to open it. And when I did edited this file second time, this time with windows and MS word, everything worked just fine.

So what's the problem here... Do I have virus which is unlikely, not even because I'm on linux, but I know how viruses works and I do not open suspicious files, I'm not going to suspicious websites and this ubuntu 14.04 LTS installed 2 weeks ago.

Something should be wrong with LibreOffice, right.. ?

Can't find any info on the internet about this issue...

And I can replicate this by creating new file with LibreOffice Writer, saved it in .odt with random text with two fonts, Times New Roman and LiberationSeriff, sent it via facebook and can not open it, same error...

Did some experiments and: it's Times New Roman font what caused the problem... What should I do? I need this font...

EDITED: So I turned off this blockage on firefox and I can download file and open it, haven't tried to open it in MS office yet, so not sure if it will work if something really wrong what libre does with MS fonts...

UPDATE: well... everything works in MS Office, nothing bad happened with fonts or document when I opened it. So everything works, but still, browser treats it as virus or spyware. :) I guess LibreOffice guys should know that...
