I am running this in Virtualbox, put the HDD and CD in a virtual IDE, and gave it 30 gigabytes of storage. I have an image of it being stuck:enter image description here

The version I use is Ubuntu 26.04 LTS

Hi everyone! I urgently need help with my printer on Ubuntu (dark theme GUI).

I have an Epson L380-Series connected via USB. Every time I send a document to print (or even a system test page), it does not print the text. Instead, it feeds mostly blank pages with random lines of numbers, asterisks, and weird characters.

I have already tried the following troubleshooting steps with NO success:

1. Cleared paragraph formatting and margins in the document.
2. Exported the document to PDF and tried printing directly from a web browser (Chrome/Firefox), but it still outputs random code/symbols.
3. Power-cycled the printer to clear its internal memory cache.
4. Deleted the printer from the system settings, unplugged the USB cable, plugged it into a different port, and turned it back on so the system would re-add it automatically.

I suspect this is a corrupted driver issue, a raw data stream conflict, or a CUPS service glitch, but I am a beginner user and don't know how to properly reset CUPS or force the correct driver for this specific model. Could anyone guide me on the terminal commands or steps to fix this?

I am new to Linux and when I use my keyboard combination Ctrl + Alt + T I obtain the following prompt:

user@ARKPC-1234567:~$

I just am trying to find out if my bootloader certificates are satisfactory for any Windows issues that may come along at the end of June 2026. It seems like sudo commands whatever they are may enable me to be an administrator (which surely I should be by default anyway).

I am used to running commands under the Windows command prompt where I obtained the following:

Microsoft Windows [Version 10.0.19045.6466]  
(c) Microsoft Corporation. All rights reserved.  
C:\Users\Mark>

I believe this is a bug but trying to report it as a bug got me nowhere. Hopefully developers will take this and run with it or maybe someone here can tell me how to do it. the ubuntu-bug command needs a package name and I don't know what to use for this. Running Ubuntu 24.04 LTS. When using the latest kernel 6.17.0-35-generic Ubuntu hangs on shutdown. When running 6.14.0-37-generic everything is fine. My hardware is an Asus ROG Strix laptop with an AMD Ryzen processor and Nvidia Geforce RFX display hardware.

I think somebody may have accessed my laptop and, amongst other things, changed the admin password. Now I cannot log in as admin. Is there a way to fix it?

Lately I've been struggling to install a few updates for the ubuntu snap store. The password that works for logging in and the terminal works, but for whatever reason it won't work on the snap store despite me having no memory or changing I at all. Any idea tl fix this?

I have a few Pi's running UC24 and wanted to "upgrade" them to UC26.

I followed the instructions for the remodel and ran into a boot failure issue on reboot.

From there I decided to install fresh. There was no UC26 option in the rpi-imager so I pulled the

    ubuntu-core-26-arm64+raspi.img.xz

image from https://cdimage.ubuntu.com/ubuntu-core/26/stable/current/ . This boots to a blank screen for me (tried both micro-HDMI ports).

Does anyone else have UC26 running on a Pi5? If so, which image did you use and were there any extra steps?

I just installed kubuntu 26.04; but then I just cannot connect to my University WPA2 enterprise wifi (like I could with 25.20, 24.04 and 22.04), signal eduroam.

This signal is configured with wpa2 enterprise, mschapv2 and peap, but no CA certificate.

At NetworkManager I (no longer? I cannot recall in previous kubuntu versions...) do not have a square to tick "No CA certificate" (initially I thought leaving it blank would mean "No certificate").

The command nm-connection-editor does show a window where I have such square - I save the configuration for eduroam, but I cannot devise where it is saved.

In fact, I can see a file netplan-NM-44fa4c25-2dc7-4a52-b83e-adcd7dd39185-eduroam.nmconnection at /run/NetworkManager/system-connections, but this file does not contain a line , e.g.,

system-ca-cert=false

(or whatever line I should provide to say there is no CA certificate). Also, this file is created at run time.

Yet, at /etc/NetworkManager/system-connections I produced a file netplan-NM-44fa4c25-2dc7-4a52-b83e-adcd7dd39185-eduroam.nmconnection with such line - but I could not devise how to convince the system to use this configuration file when I call for a connection to eduroam.

Currently I see some alternatives, that I do not know exactly how to put in action: i) the NetworkManager to be instructed to not use a certificate, even if it is does not present this option at its configuration window ii) the gui issued by the nm-connection-editor command to record a configuration file that does become used iii) to connect by the nmcli command, but to use a specific configuration file

I googled around , but I must miss some detail here. Thank you,

J.

As indicated, I add to the original question my new comments:

Thanks heynnema and Andrei Borzenkov for inputs.

a) I tried netplan apply and retested, no difference (so I learn there is a /etc/netplan/ directory with some .yaml configuration files); b) I thought my problem might be the CA certificate - well I might not be sure of this. I try to connect to eduroam and it keeps asking for my password, again and again. I do get this eduroam connection through windows 10 (dual boot machine). c) If I understand, this issue of CA certificate might not be the culprit. So I report what I observe at trying to log and I also write below the log "with journactl" with the "relevant lines" (sorry for the length):

Since the 26.04 kubuntu upgrade, when I try to log in with ssh using a password, I get a graphical window box asking for the password. I cannot emphasize enough how much I do not want this.

So I disabled the use kdewallet in the system settings, but that wasn't enough. I saw I also had to remove ksshaskpass, which I did, only to receive ssh_askpass: exec(/usr/bin/ssh-askpass): No such file or directory, so I installed ssh-askpassand now there is a lame looking box asking for a password. Neither of those boxes work, and worse of all they break the use ofsshpass` which I need in some scripts. Yes, I know "use keys", but I can't on some systems, it's not allowed, don't ask me why.

So, how do I get ssh to ask for the password in text, as is traditional ?

I have been using Ubuntu and Windows without issues on a dual-boot setup. The Windows drive mounts automatically on startup in Ubuntu.

However, I want to re-enable BitLocker to encrypt the Windows drive. After reenabling it, Ubuntu will not start. I get the following message:

You are in emergency mode. After logging in, type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, or "exit" to continue bootup. Press Enter for system maintenance (or press Control-D to continue):

If I type "systemctl reboot," nothing happens. If I type "exit", the same message appears again.

I have disabled Bitlocker again, but still, I would prefer to have the Windows drive encrypted (it is a laptop I sometimes travel with).

Thanks!

enter image description hereHI team ubuntu.

I have installed 26.04 with cinnamon desktop 6.14 to get custom as desklets, applets etc... but they don't work. the sever does not run and give nothing to see !?

thank you all for your lights.

I have installed 26.04 with cinnamon desktop 6.14 to get custom desklets, applets etc... but they don't work. The server does not run and gives no error messages!

I have a good wired connection, but I can't get anything with applets settings to download. it sounds the server doesn't run at all. I hope the developers team will take a look at it. btw, it always worked with Mint!

I was a user of RealVNC, because it allows to connect to my computers across any network after signing in with RealVNC account.

However, RealVNC does not support Wayland, and KDE will drop support for X11 in 2027. While Kubuntu 26.04 is going to be supported for five more years, I want to prepare for the full Wayland transition.

There are ways to connect to Wayland via TigerVNC, and it is also possible to connect to PCs in a different network (via tailscale), as explained in this answer. However, this method has some bugs, e.g. the ctrl button does not always work, which is a pain, because I need to run code in my workstation, and it is hard to copy/paste/undo without the control button.

I have read that there are other available options such as RDP, RustDesk and more, but I don't know if they properly support Wayland. I have also read conflicting comments about what actually works, apart from VNC.

What are the other options (apart from TigerVNC) for KDE Wayland, and how to set them up? Does it also support remotely logging in (this feature is supported in RealVNC, but does not work for the related answer regarding TigerVNC, which is running from a logged in account)?

It would be nice if the method also supports other Wayland setups (e.g. GNOME), but that is not strictly necessary.

I've done this many times on different systems, but this has me puzzled:

OS: Ubuntu 26

Had an external drive that I was mounting using the fstab.

/dev/sda1 /data ext4 defaults 0 0

I removed the drive and of course it rebooted and went into recovery mode. So I edited the /etc/fstab and removed the external drive mount. Now when it reboots, it still hangs up on trying to mount that drive.

Does Ubuntu 26 store the information that is/was in the fstab in another spot? Like a database or other file? I noticed the fstab in Ubuntu 26 is very minimal, so I'm guessing there is some sort of other place that needs to be updated??

I installed Ubuntu 26.04 recently on a new device and enabled full disk encryption.

When I enter the password, sometimes the system does not recognise it and prompts me to enter it again. When I do that, it gets stuck on the loading screen and never boots. Pressing ESC showed me some error messages about the crypt library.

How can I solve this problem? I am forced to do a force restart at least once a day because of that. The keyboard layout is shown to be de So I don't think it is related to a layout mismatch.

#Edit1 Logs below executing journalctl:

If I run reboot command the system logs in without peoblems. So i happens roughly 50% when booting from an off state. It does not happen at all on reboot.

[UPDATE]: I found some threads on Framework's Community boards, and apparently this is a known issue with the AMD motherboard, and a workaround is to use a USB-A to USB-C cable instead of a USB-C to USB-C. I tried it, and was able to pair the phone successfully and tether it to share the network! Would prefer not to involve USB-A, but it seems to be a functioning workaround.

Original post:

I have a Framework 13 laptop (AMD cpu) with Ubuntu 26.04 freshly installed and updated. I plug in my iPhone 16 Pro (iOS 26.5) via USB-C cable, and Ubuntu shows an "Untrusted Device" dialog, and the phone shows a "Trust This Computer?" dialog.

Before I can click "Trust" on the iPhone, the dialog is dismissed. After 3-4 seconds, Ubuntu overlays another "Untrusted Device" dialog, and the iPhone again flashes the "Trust This Computer?" dialog.

It keeps repeating this endlessly, and never gives me enough time to click "Trust" on the iPhone and type in the pairing code.

The USB-C cable is a known working cable from Apple, which works fine to pair/tether the phone to a MacBook. I believe I've also paired this phone and laptop on a previous install of ubuntu, but I hadn't used this laptop in a year, and did a fresh 26.04 install recently, and I'm traveling, and surprised that I can't seem to pair the two to share my phone's internet.

The workaround is to use a wireless tethering method (bluetooth or wifi), but I can't plug my phone in to charge off the laptop without it making both the phone and laptop pop up a dialog every 3-4 seconds.

I spent a couple hours this morning with Claude to see if it could help me track down the issue, and I asked it to summarize what we tried, and here's the relevant bits from that summary:

Root-cause isolation. Verbose usbmuxd logging showed a consistent per-cycle pattern: the device enumerates cleanly, usbmuxd connects, the configuration is switched (0 → 4), preflight begins, reaches "Waiting for user to trust this computer," and then ~0.6–0.8 seconds later the device drops (Device RX aborted due to error or disconnect / Removed device) and re-enumerates. The disconnect timing is fixed and regular, and occurs with nothing on the host actively tearing down the connection — usbmuxd is idle in the trust-wait state when the drop happens. This points to the USB connection being torn down below userspace, at the USB host-controller/xHCI or device level, rather than a pairing-software failure.

What we ruled out (no effect on the drop). Different USB-C ports; the Apple cable (works on macOS); stale host trust state (cleared /var/lib/lockdown, and did Reset Location & Privacy on the phone); the udev rule 39-usbmuxd.rules (masked it entirely — no change); GNOME gvfs/gvfsd-afc contention (masked the volume monitors — the gvfs storm stopped but the ~0.8s drop persisted unchanged); daemon lifecycle (ran a single persistent usbmuxd --foreground so no socket/udev respawn could interfere); and the ipheth kernel module (unloaded it with modprobe -r ipheth — the device still dropped at the same ~0.8s mark with the driver entirely absent).

I have Preserve Battery Health option enabled on Ubuntu 25.10. It is limiting the battery charging capacity at around 80% level but even after shutting down the laptop and turning it on next morning, I see the battery level stays at 80%.

Doesn't it suppose to start at 100% and go down to %80 and stay there? Since OS have no control on the battery after shut down, it should be charged to the maximum level.

What am I missing?

I have a ASUS TUF GAMING laptop with two separate nvme each 1TB. On first one windows 11 installed with bitlocker disabled. And on the second one I installed Ubuntu Raccoon. But during installation Ubuntu installer reported bitlocker detected. Anyhow installation finished without any problem. I did not used any encryption either. Just created a user to login. I have created a swap, efi and an ext4 partition. After login, I could not mount the ext4 partition as it prompts for a password!? By the way, I checked the disk and discovered a Microsoft reserved partition in front of queue which was strange. Any idea? Tks

I'm currently using Ubuntu 25.04 and recently tried changing the default terminal from gnome-terminal to ghostty.

I tried running sudo update-alternatives --config x-terminal-emulator, but ghostty wasn't listed.

I then ran sudo update-alternatives --install /usr/bin/x-terminal-emulator x-terminal-emulator /snap/bin/ghostty 50

After that I could see ghostty in update-alternatives, but, even after rebooting, when I open the terminal with Ctrl+Alt+T, gnome-terminal still opens instead.

What am I missing here?

I have an Ubuntu 24.04 LTS server with a bunch of users, all having accounts on it and their home directories being available via Samba.

I need to allow each user to be able to change its own Samba password using the command smbpasswd but it can't work, I get following error:

machine 127.0.0.1 rejected to change the password with error: {Access Denied} A process has requested access to an object but has not been granted those access rights.

As far as I was able to look for a solution I couldn't find a good one. Do you have any ideas?

I would like to transfer PDFs, MP3s, and MP4s from Ubuntu 20 Linux to iPhone 16, but I am struggling to find a way to easily do this, and I need your help.

On Android, I'm very used to connecting my phone to my computer with a USB cable, simply copying files over from my computer, locating them via the Files app on Android, and opening them with whatever app makes sense for the file type. I'd like to do the same thing with iPhone.

When I plug my iPhone into my computer via USB, I see two mounts in Files: "Documents on iPhone" and "iPhone". "iPhone" shows pictures and videos from my camera. If I try creating a folder there, I get an error: "Error while creating directory testing123. There was an error creating the directory in gphoto2://[...]. Error creating directory: -6: Not Supported".

In "Documents on iPhone", I see app icons for GarageBand, iMovie, Keynote, Numbers, Pages, Brave, and Firefox. If I double-click Brave or Firefox, I see a Downloads folder. If I try creating a folder there, I get an error: "Error while creating directory testing123. There was an error creating the directory in afc://[...]/Downloads. The connection was interrupted." At that point, I can no longer access ("This location could not be displayed. Sorry, could not display all the contents of "Brave": Unhandled Apple File Control error (2)"), and I have to remount.

Many recommend libimobiledevice and ifuse. I installed those on Ubuntu and can successfully mount my iPhone and copy files to it, but I can't see the files or access them from my iPhone.

I enabled Bluetooth and could successfully pair my iPhone with my computer, but I didn't see any option on either side to initiate a file transfer via Bluetooth, and https://help.ubuntu.com/stable/ubuntu-help/bluetooth-send-file.html.en says "Send Files does not work on unsupported devices such as iPhones."

I don't want to pay for an app to do what I think should be a very simple thing.

I don't want to use cloud services (such as iCloud, Dropbox, Google Drive) because I don't want to upload gigs of data and then download gigs of data. Same applies to email and messaging.

I don't have a Windows or macOS computer to work with.

I don't want to jailbreak my phone.

How can I successfully copy PDFs, MP3s, and MP4s from Ubuntu 20 Linux to iPhone 16 and open them from iPhone?

Im trying to install the IPTV program Hypnotix on Ubuntu 23.04. But i have not succeeded. I have googled around a bit and im starting to think the problem is that Ubuntu 23.04 is very new and for some reason doesnt support Hypnotix yet? Does anyone know what the problem might be? Best regards Ubuntu newcomer Emil

Just upgraded to 22.04 from 21.10. Flameshot not working. I click on the Flameshot icon and nothing happens. How to fix this?

I tried finding a similar question and did but there's a caveat though, older questions use --no-cert-check option which is removed due to security reasons and I don't know the exact fingerprint for the server as it will change from time to time. I need to pass two inputs to the openconnect command using something like echo -e "arg1\narg2" but was not successful.

How can I do it? (below is the command I used):

echo -e "yes\nmypassword" | openconnect serveraddress --user="myuser" --passwd-on-stdin

I'm encountering a connection issue to my university WiFi network that I cannot solve: when attempting to connect, I get the following message with dmesg -T :

[ven. oct. 11 12:32:04 2019] wlan0: deauthenticating from X by local choice (Reason: 3=DEAUTH_LEAVING)

This problem has already been pointed out in the forum, but none of the solutions I tried worked:

• Disabling the powersave for WiFi (in /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf set wifi.powersave = 2 ).
• Changing from NetworkManager to WICD.

• Adding the following lines to /etc/sysctl.conf:

  net.ipv6.conf.all.disable_ipv6 = 1
  net.ipv6.conf.default.disable_ipv6 = 1
  net.ipv6.conf.lo.disable_ipv6 = 1
  

None of these worked.

It's an old Asus laptop that i use sometime for programming. It's battery is dead so i have to be connected to power supply whenever i have to use. Was working fine for the last few years(even with a dead battery). Today while i was working on it, the power plug got dislodged from the socket and the computer instantly shutoff (normal, happened a lot previously). But this time when i tried to start it up, the first time- i could hear the wheezy sound(as usual) but the screen was complete black as if it was shutoff. I gave it some time but didn't see anything on the screen so i rebooted. Now the screen lights up proper (as usual) but i get the 'This is not a bootable disk ...Insert a bootable floppy and press any key...' error on the screen. I tried these at the BIOS setup

1. enable/disable UEFI

2. check boot priority ( there's only the hard drive and the dvd drive with the hard drive at the top priority).

No result.

I had a live USB of a Kali distro and i could boot from it (UEFI mode). My hard drive is GPT. It has Ubuntu 16.04 and Lubuntu 18.10 dual booted. Six partition including the sda1(grub_boot). There is no secure boot option in my BIOS setup.

Could anybody suggest :

1. Where should i look to see whether it is a hardware related problem or just the grub is messed up.

2. Should i go ahead with a Boot-repair or wait until it am sure where he problem is. Thanks in advance

                   :Update:

I restarted my system and now, as Ill luck would have it , the screen doesn't even light up though i can hear the fan noise see the power lights. Restarted a dozen of times but to no use so gave up. In the evening, i tried as the last ditch effort but now it's seemed the problem got worse as i could not even hear the fan noise or in fact no noise at all. So couldn't figure out if the POST test is happening or not after pressing the power button. So as a final effort, i started the pc on last time and kept in on for a good 20 minutes and then restarted the System. seems it solved the Dead screen issue and now i can see the pc logo and can enter the BIOS setup. But however, the initial problem still persist so now i am going to do some smart test from the live Kali on flash drive. This is a whole new experience, will update if get any major result.

I need to use a third party web service which is accessible only through Cisco AnyConnect VPN. I'm using OpenConnect on Ubuntu to connect to this VPN using host, username, and password.

However, instead of having to manually connect every time we need to connect to the service (since the service is being consumed by a script that runs on daily basis), I would like to set it up once and have itself reconnect when the tunnel breaks.

Is there a way for us to connect openconnect client (or any other similar client for Cisco AnyConnect) to automatically reconnect when the connection breaks.

Alternatively, is there a way to login without username and password and store that configuration somewhere so we can automatically respawn the process when it stops.

Please note that this is all on a server, so no GUI.

I have a directory with a lots of images but they are in the wrong orientation. I want to rotate the images to correct the orientation (mostly ±90^o). Using image (shotwell photo) viewer I can rotate them individually by clicking the rotate button but that's too tedious.

I looked at man shotwell and shotwell --help-all but there's nothing that explains how to invoke the rotate command from the command line.

Is there any way I can invoke the rotate command of shotwell (or any other viewer) from the terminal? Or any other methods to rotate images are welcome too.

I'm entirely new to Linux/Ubuntu so please bear with me.

I currently have Windows 7 32Bit and wanted to install Ubuntu. I used the installation off the website and copied it onto my bootable USB. As I installed Ubuntu it says I need to reboot my system - so I did.

As I try to boot up in Ubuntu it just simply says 'MBR-helper missing' and nothing else, however, it lets me boot back up in Windows fine.

Is there a way to get around or repair this error? I can't find a clear answer on forums.

Is this error because I copied it into my USB? Or is this a common yet fixable problem?

Please help.
