i had problems with my internal HD so i was using an external one to boot from. recently i decided it was time to fix the problems i had, so i formatted the internal HD and installed ubuntu on it. now i want to copy all my documents from the external HD back to the internal one. the problem is that i can't mount the external one. when i plug it in, ubuntu only shows me a 2.1 GB partition, but the one i need is 2 TB in size. is my system FUBAR? am i doing something wrong?

BTW, booting from the external HD is not an option either, because then i can't access the internal HD. i have to enter the admin password, but that doesn't do me any good. and it won't accept my user password.

how can i get my files back?

Currently using KDE on Ubuntu 22. I have a CUPS server that's using SSSD to provide authentication from LDAP when printing. I've got a printer that I am allowed to print since I'm in the correct group. Adding that printer to a Windows machine works as a charm (I add it, a popup asks for an username and password, all good, printing works).

The issue is when adding that same printer via the KDE Printers menu. Same, add via ipp, I'm asked for an username and password but those don't seem to work. I keep getting No authentication data provided in the local cups server, I don't even see the request on the remote cups (probably would if I'd enable debug, but since this is in use, I think that's going to make life a living hell - going through a ton of print jobs from a few tens of PCs).

Also, in the local cups server I see password_cb(prompts=\"Password for <username> on <cups server>? \" [...] password=(nil) so if I get this right, it uses no password to authenticate, even though the user is correct - so the username is taken from somewhere (not the same user as the local user).

Any help would be greatly appreciated.

Thank you!

When I try to start Okular to view PDFs, I get this error:

/snap/okular/173/usr/bin/okular: error while loading shared libraries: libPlasmaActivities.so.6: cannot open shared object file: No such file or directory

Also, I'm not sure if this is related, but when I start the Snap Store and click on "Installed" to try to view the installed applications, the page is completely blank. Nothing ever loads.

If I run

snap list

on the command line I can see all the installed applications and okular shows up.

I tried running

sudo snap refresh
sudo snap remove okular && sudo snap install okular

to fix ocular, but it still gives the error above. On the command line after running that last command I get:

okular removed (snap data snapshot saved)
okular 25.04.3 from KDE✓ installed 

Context

I have a dual monitor setup for normal daily use. My primary monitor (DP-1) is in landscape orientation and my secondary monitor (DP-2) is rotated 90 degrees clockwise (portrait right). This layout is easy to setup with Ubuntu's Setttings > Displays.

However, in some situations it is preferable to disconnect the secondary display and only use the primary. Going back into the settings and manually switching between these two "profiles" happens often enough that it is a bit annoying.

My ideal workflow would be to setup a hotkey shortcut (e.g., win+p) to run a script that swaps between these two setups. However, nothing I've tried or found online works:

xrandr recognizes my monitors and provides info (xrandr -q) but is unable to actually change anything:

xrandr [-d :1] --output DP-2 --off

#> X Error of failed request:  BadMatch (invalid parameter attributes)
#>   Major opcode of failed request:  139 (RANDR)
#>   Minor opcode of failed request:  7 (RRSetScreenSize)
#>   Serial number of failed request:  28
#>   Current serial number in output stream:  29

# Nothing happens...
xrandr --output DP-2 --rotate left

It appears that this is probably because my distro uses Wayland instead of X11, which has been great for most things. But, I haven't figured out how to manage Wayland displays from the terminal.

Question

How can I swap between these two "profiles" with a script and/or shortcut, macro, etc.?

I think I have made the mistake of installing Ubuntu based Winux. I have uninstalled the microsoft edge browser but the desktop shortcut keep coming back on restart/reboot.

Any suggestions on how to get rid of this pesky shortcut would be greatly appreciated.

I updated to 25.10 a couple of days ago. Everything seemed to work fine but...

• VMware Workstation 25H2: does not update correctly its window and menu bar components. Sometimes the virtual machine looks online when its shutdown. Sometimes resizing the workstation window does not affect the virtual machine desktop (when it should, of course). Sometimes the menu selected/m-over option is not highlighted, but it is clickable. It's kind of weird.

• Audacity: The UI components are clickable but they're not updated on screen. This has been fixed by switching to Gt mode from GTK mode.

Has anyone had similar issues? Do you have any idea how to fix them?

Google Chrome is not displaying websites correctly. This issue has made Google Chrome completely unusable, however Firefox works just fine. Here is a screenshot of what I am talking about.

Interestingly, when I was taking the screenshot the bug was even effecting the display of the screenshot box, so the issue effects the screen outside of just Chrome.

I think the problem could be with the graphics driver for my computer. Another issue I have is the computer won't go into Suspend when I close the lid and if it is in my backpack it will get warm. I have dug a lot into that issue, and it seems like the graphics driver could be the culprit as well.

Specs:

• Ubuntu 22.04.2 LTS
• Computer Model: Dell Inspiron 7415 2-in-1
• Processor: AMD Ryzen 5 5500u with radeon graphics x 12
• Graphics: RENOIR (renoir, LLVM 15.0.7, DRM 3.47, 5.19.0-46-generic)

On Ubuntu 22.04.2, I would be glad to ear about a native and secure way to generate TOTP codes for using in any given application which needs 2FA.

Do you know an open-source way of doing that directly on an Ubuntu computer?

All tutorial I can find are based on the "mobile app" way (e.g. using Google Authenticator), which I cannot use because I don't have any other mobile device than a laptop.

I installed Ubuntu 22.04 in dual boot with Windows but my wired network doesn't work in Ubuntu. WiFi does work. I tried several tutorials on the internet, but none of them work in my case. My system is a fresh installation. I didn't modify any network configuration.

My cable is plugged in and works on Windows so it's not a physical issue or a router issue.

I use Ubuntu with WiFi at work, at home I connect the PC with the cable internet (I don't have WiFi at home). I start Ubuntu and the internet does not work. I have tried a lot to solve this, but nothing works. I am running on Windows to ask for help here because I have internet on the wired connection in Windows. I came back to Ubuntu to take some screenshots of my internet connection, but now the internet works. What is going on? It seems that it began to work again after I started Windows and came back to Ubuntu.

(It happened more than once).

Results of sudo dhclient:

About the Fast Boot, it was already disabled.

------------ Solution ---------------

My internet driver was wrong. It was for 8169, but my hardware is for 8168 driver.

Running sudo apt install r8168-dkms solved the problem. You will only need to set a password (write it down) and after a reboot use this password to set MOK.

Steps after sudo apt install r8168-dkms and reboot:

Is there anyway of getting the individual CPU temps?

I need to access an option.c file inside the path [linux-src]/drivers/usb/serial/option.c. I update my kernel version:

    admin@sintrones-abox:~$ uname -r
    5.18.14-051814-generic

Inside the folder /usr/src I still have the older kernels directories:

Problem

From these screenshots below, I believe that I have successfully configured my Ethernet adapter.

Using lshw to showcase the established interfaces:

Using ifconfig to show the configuration of the network interfaces:

After configuring my Ethernet adapter, I connected local device to my desktop and attempted to ping it to test whether there is a successful connection. Below is the result of that ping:

Initially, there was some weirdness surrounding whether the interface was able to detect a connection.

Showing that I set my Ethernet IPv4 settings to manual instead of automatic DHCP:

When this was set to Automatic (DHCP), the Wired part of the settings would fail to connect with Ethernet. As a result, I manually configured my address, netmask, and gateway, as you can see through the previous screenshot. After this, the settings menu began to show that I was connected to some device via Ethernet, as shown here:

Therefore, my problem is that I should be able to ping the device that is directly connected, but I am unable to. I hooked up the device to another desktop via Ethernet and saw successful pings, so I wanted to know why the pings were failing for a device directly connected to the desktop in question.

What I've Tried

• I have done power cycling on both the device and my desktop, and I have checked for loose connections

• I have looked into the potential of ACLs, rate limiters, and other such firewalls, blocking the receipt of packets. I am very new to network security, so I might have missed something, but I do not believe that this is the issue, since nothing really showed up.

• I have tried directly adding the IP I'm trying to ping and its host name into my route

• On that note, I have run traceroute -I 192.168.137.11 and only the IP of my PC appeared

Possibly Useful Background

The desktop in question was newly built with a motherboard with a component that only works for kernel versions 5.15 onwards. The desktop is running Ubuntu 20.04 because I need to use a feature that is exclusive to the MoveIt version for ROS Noetic, among other things. Thus, I am currently using kernel version 5.15.31. My Ethernet interface is a Realtek RTL8125. Installing the drivers for it was a hassle because most everything I've tried through the Realtek website:

https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-pci-express-software

and through using sudo apt-get install r8168-dkms have failed, mostly due to issues involving Linux headers. After removing several other kernel versions, removing and reinstalling other packages, what eventually allowed me to interact with the Ethernet interface (I think) was by running:

sudo apt install realtek-r8125-dkms

I believe the successful installation of this package, as well as the earlier screenshots, indicates that the driver has been installed, but I don't really know if this is true, and I have no idea if the kernel version that I am using is interfering at all with the networking.

I have a 1TB Toshiba USB HDD connected to the USB 3.0 port in my laptop (Asus X550C). I am using Ubuntu 18.04 (kernel 4.15.0-166-generic).

I used to sleep/wake up the computer with the USB drive attached and everything resumed normally. However, since one Ubuntu update (I cannot tell which one) I get I/O errors from the USB disk after waking up:

user@asus:/media/user/HDD$ ls
ls: reading directory '.': Input/output error

All programs that have a file opened from the USB disk crash after resume because they cannot access the disk.

What I have observed by trial and error:

• New programs can access the disk successfully. However, those programs that went through the sleep/wake up cycle never recover access, even though the disk is working again
• There is one exception: if I leave a shell opened and pointing to a directory in the disk, I get I/O errors. However, if I type cd . errors go away and HDD works again (only cd ., any other command results in IO error)
• If I attach the HDD to the USB 2.0 port, it wakes up successfully
• If I attach a USB flash drive (not HDD), it wakes up successfully

It is like the current directory is somehow lost for programs that go through the sleep/wake up process. Programs opened after wake up work nicely. This only happens for an HDD connected to the USB 3.0 (like some kind of racing condition).

As you can see, the only difference between the two logs is that in the USB 3.0 the HDD gets disconnected from the USB bus:

...
[   86.415368] usb 4-1: USB disconnect, device number 2
...

So when the OS tries to access files from the HDD, the HDD is not ready and the error happens.

Any idea what might be causing this disconnection only under USB 3.0?

Thank you very much in advance.

I would like to enable or disable certain options in the software-properties-gtk application via the command line.

Examples of the options that I am interested to control via the command line are shown below:

I suspect the command software-properties-gtk --enable-component=ENABLE_COMPONENT would allow me to implement what I want, however manpage does not elaborate what values can be used to replace ENABLE_COMPONENT.

$ software-properties-gtk -h
Usage: software-properties-gtk [options]

Options:
  -h, --help            show this help message and exit
  -d, --debug           Print some debug information to the command line
  -m, --massive-debug   Print a lot of debug information to the command line
  -n, --no-update       No update on repository change (useful if called from
                        an external program).
  -t TOPLEVEL, --toplevel=TOPLEVEL
                        Set x-window-id of the toplevel parent for the dialog
                        (useful for embedding)
  -e ENABLE_COMPONENT, --enable-component=ENABLE_COMPONENT
                        Enable the specified component of the distro's
                        repositories
  --open-tab=OPEN_TAB   Open specific tab number on startup
  --enable-ppa=ENABLE_PPA
                        Enable PPA with the given name
  -k KEYSERVER, --keyserver=KEYSERVER
                        Legacy option, unused
  --data-dir=DATA_DIR   Use data files (UI) from the given directory

I would appreciate instructions on using this command.

I have a Lenovo IdeaPad 14 G3 (AMD Ryzen 7 5700U, 16GB RAM), which is only a week old. It came with one 512GB NVMe SSD and Windows installed on it. I installed a second 500GB NVMe SSD and installed Kubuntu on that drive to have a dual boot system.

Everything seemed to be working fine, but after a few hours of use the laptop randomly crashes in a weird way. First it starts behaving weird like I can't save or open files, the context menu of Dolphin or the desktop has missing entries. Then after a few seconds some Icons start to disappear and finally the screen turns black and I only see my mouse cursor. I then have to hold down the power button until the laptop shuts off and restart it, after which everything works fine until the next freeze in a few hours.

While it was slowly freezing I saw that Dolphin only showed my first SSD with Windows on it, but not the second with Linux on it. Maybe the second SSD is randomly disconnecting?

It happened both on battery and while plugged in, I also disabled secure boot in the UEFI, but the error persists.

The last freeze was Jul 21st at 16:32 local time, I shut it down that minute and waited with the restart until 16:34, but my syslog only has entries after the restart, it does contain some weird characters that break this post tho, so here it is as a screenshot:

^{Click image to enlarge it.}

This is a snapshot of syslog around that time. Sadly I have no idea how to troubleshoot this I don't know if there are any other logs that could be useful or any commands I could check my SSD with. I suspect the SSD with Kubuntu on it is randomly disconnecting and the system freezes up as it gradually tries to load stuff into RAM, but I don't know how to go about validating and fixing this theory.

This is my first time trying to do the below task. So far I followed these links.

• Fastest way to migrate to a bigger SSD (18.04)
• How would I speed up a full disk dd?
• https://www.tigraine.at/2014/01/04/how-to-upgrade-to-an-ssd-with-minimal-effort

I'm currently running Ubuntu Linux installed on a 240 GB SSD and planning to upgrade it with a 500 GB SSD as is. Once everything is cloned (including the partitions) I plan to swap the smaller SSD with the larger SSD in the laptop and move on.

Steps I've followed so far:

1. I've created a bootable USB flash drive for linux (Pass).

2. Booted the laptop using the flash drive (Pass)

3. Connected the new 500 GB SSD with laptop using the external SATA-III to USB 3.0 cable (Pass)

4. Successfully formatted the new SSD using the Disks app (Pass).

   

5. Successfully executed the dd command to copy/clone the content of main partition from older SSD to newer SSD (Pass)

   

6. After copying I execute the sudo lshw -C disk I see the original 240 GB SSD and the flash drive details, but not the newer SSD.

   

7. I have no clue about how to bring in the remaining partitions from the 240 GB SSD onto the newer SSD

   

Once I swap the SSDs I wish to have similar partitions on the newer SSD. As of now I'm clueless of how to carve out the remaining two partitions on the newer SSD.

Please let me know:

• If I can start using the newer SSD in existing condition without any partitions?
• If I need to execute any more steps that I'm missing here.

I've created a simple script that pings a server, and reboots my machine if the server doesn't respond. if it does respond, it just exits the script.

I've added the script to cron via crontab -e, specifically as follows

*/8 * * * * /root/hive/bin/pingtest

once I add it, I can see cron executing the "pingtest" every 8 minutes just as I commanded. however, once the machine reboots (for whatever reason), that specific line in crontab is gone, it doesn't presist through reboots.

I've tried editing via root, I've tried editing via sudo, but nothing persists.

what am I doing wrong?

I just build my first PC, turned it on for the first time, and attempting to install Linux Ubuntu 20.04.1 LTS from a bootable USB.

As many others have had the "decoding failed" problem I cannot seem to figure out how to use any of the solutions posted to fix the issue regarding my situation.

Any or some advice would be greatly appreciated as I have no idea what I am doing nor have any technical knowledge.

Thank You

Ubuntu prompt (I clicked enter on the first line ubuntu)

I am experiencing a new problem after finally getting Ubuntu 18.04 to install on my laptop (could NOT get another OS besides Windows on it), but that is for another question.

The problem is, at random times my laptop will act like it disconnects from the power adapter and the reconnects. I hear the notable "tick-tick when something is disconnected from Ubuntu, then I see that the power icon at the top of the screen doesn't show the lightning bolt any more. Then a few moments later, I hear the sound of something reconnecting, and then the lightning bolt is back in its place.

I do NOT under any circumstance want to promote Windows here, but I do want to point out (because it may be helpful) that this issue wasn't present in Windows 10. I also want to point out that my hardware is very weird. Here is the output of lshw:

Here is also a screenshot of all of the errors that show up in my logs: screenshot

I am only posting the error logs just in case someone notices that something in there is related to the issue that I am having. If I can provide more information, please tell me and I will edit my question ASAP!

I would also like to note (just in case) that I was NOT able to get ANY other flavor of Ubuntu installed besides the vanilla version. The installer would keep crashing at about 30% creating partitions, but that is for another topic itself. I also have NOT done anything special to this system, just installed the OS and added my usual programs,that you can see on the side of the screenshot.

I also just noticed these weird lines in dmesg.

Are they related to what's going on?

I am trying to install ubuntu server 18.04 inside proxmox. At the network configuration page, ubuntu complains that autoconfiguration failed and gives me the choice to continue without networking. The installation, however, completed smoothly, despite the fact that no networking is present... I still have no internet access after the installation finished, so I went on to configure a static ip. Here is my netplan yaml configuration:

network:
    version: 2
    renderer: networkd
    ethernets:
        ens18:
            dhcp4: no
            addresses: [10.0.1.101/24, ]
            gateway4: 10.0.1.1
            nameservers:
                addresses: [8.8.8.8, 8.8.4.4]

ip route on the vm gives:

default via 10.0.1.1 dev ens18 proto static
10.0.1.0/24 dev ens18 proto kernel scope link src 10.0.1.101

ip route on the host gives:

default via 10.0.1.1 dev vmbr0 onlink
10.0.1.0/24 dev vmbr0 proto kernel scope link src 10.0.1.100
10.0.1.0/24 dev vmbr1 proto kernel scope link src 10.0.1.101

/etc/network/interfaces on the host contains:

auto lo
iface lo inet loopback

iface eno1 inet manual

iface eno2 inet manual

iface eno3 inet manual

iface eno4 inet manual

auto vmbr0
iface vmbr0 inet static
        address  10.0.1.100
        netmask  255.255.255.0
        gateway  10.0.1.1
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0

auto vmbr1
iface vmbr1 inet static
        address  10.0.1.101
        netmask  24
        bridge-ports eno2
        bridge-stp off
        bridge-fd 0

Pinging anything, including 10.0.1.1 the gateway, gives destination host unreachable. SSH gives no route to host

I have a usb device ext4 file system, I manually mount it like this

  mount -t ext4 /dev/sda1  /mnt/sdcard1 

then change permissions manually to enable others to write to it.

What line should I use in fstab so that all users have read/write permissions on it..

How I can fix the Error mounting /dev/sdb1 at /media/... It works pretty good in the past but I made a clean installed of Ubuntu 14.04 LTS and the Error mounting coming. I try to fix it with with Gparted, ntfs-3g, pmount, but this programs can't find the external HDD. But when I boot put the USB drive with Ubuntu 14.04 on test mode this can find and read my external HDD. How I can fix it?

About a month ago I installed ubuntu 14.04 on my computer. I did not replace the Windows 8 that I was previously using. While ubuntu has by and large been working very well, one issue is that grub does not load when I restart my computer. If I want to switch operating systems, I have to restart my computer and then go into the BIOS and switch the boot mode from CSM to UEFI (or vice-versa).

While it is not the end of the world to have to do this, it would be more convenient for me to have grub. Also, I am planning to install another Linux distro in the near feature, and without grub working I am worried that I won't be able to switch between my Linux distros.

Does anyone have any suggestions for getting grub to work?

I recently returned to Ubuntu (14.10) and I'm currently trying to get my multiple monitor setup to work properly.

It worked fine after the first setup in the desired configuration: A 1600x900 built-in monitor (Thinkpad T430) besides a 1920x1200 external Monitor (Asus VK226H) which is connected by DVI or VGA or mDP.

However, after the first reboot it greeted me with 'the selected configuration for displays could not be applied' and showed me a partially overlapping and highly distorted background with weird placement of the launcher and a non-functional mouse interaction (does not click where it's shown). Switching to mirrored mode made everything functional again.

Having a look at the X Server Configuration I've noticed that only the external monitor is being represented in the layout graphics and 'Selection' dro down menu while displays shows them both. The 'the selected configuration for displays could not be applied' started to pop up almost anytime I apply something to displays or X Server, apply something to displays, reboot or reconnect the external monitor (no matter which port).

Here are 2 screenshots with driver rev 331 showing both displays and the X Server config before and after I managed to get everything visible/not overlapping after a reboot.

^{Click image to enlarge it.}

While it was heavily distorted along the vertical dimension (and parts of the desktop off-screen) on the physical screens this is not reflected in the screenshot*

Failing horribly with lots of X Server settings, I decided to try the legacy drivers. I've purged the current drivers via this method and installed the 304 version though Software & Updates. The same thing happened. It worked after the initial setup and installation but failed again after a reboot. The built-in monitor still did not show up in X Server.

Since this didn't achieve anything I've reverted back to 331 and tried it once more with the same result. Everything looks fine to me in lshw and dpkg.

At this point I have no Idea what to do since it's obviously a problem with the placement of my screens on the virtual screen but it doesn't show all of them in the configuration menu. How do I get it to show up so that I can configure everything properly?

I have a Nvidia GT 630 with two LG Flatron E2242 screens connected. One of them is connected with a DVI/VGA connector because the card has 1 DVI and 1 VGA output.

The driver (got the latest one) can't query the one connected with the DVI/VGA connector for its EDID and I can't get it to work on a resolution bigger than 640x480.

How can I get it to work on 1920x1080 like the other one?

I am using the bash version 4.2.37 at ubuntu 12.10. But since ubuntu 12.04 I am unable to export arrays in bash...

This is an example (type these lines in the command line, it is not a script):

export astr=(a "b c" d)
declare -p |grep astr
bash
echo ${astr[@]}
declare -p |grep astr

echo outputs nothing...

declare -p |grep astr outputs nothing either...

What I am looking for is an workaround, because as far I know that is considered an known bash bug.

EDIT: btw, if possible, the workaround could avoid creating temporary storage files for the array as I may run the same script simultaneously on different shells.

I'm using an EVDO usb Modem on 12.04. It works perfectly fine for few times. But now on wards when ever I try to connect it shows not enabled in status . I tried to enable it by ticking "Enable Mobile Broadband" but still it shows not enabled but that option gets a checked(tick) mark. And when ever I restart my system "Enable Mobile Broadband" option autamatically unchecked. Any help please

I imagine this is a basic gotcha, but I can't see it. I have a system with 2 (physical) hard drives. The boot system (/dev/sda) was running 10.04 & the second drive (/dev/sdb) was just a mounted filesystem.

I did a clean install of Ubuntu 12.04 overwriting /dev/sda (not an upgrade) and now cannot mount the second drive, so I do not know what to enter it into fstab.

I had expected to use: /dev/sdb /tera ext4 defaults 0 2, but even manual mounting fails. (I also have tried various -t options on the off chance.)

$ sudo mount -t ext4 /dev/sdb1 /tera
mount: wrong fs type, bad option,
bad superblock on /dev/sdb1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so
