I tried to upgrade to 26.04, but I get a network error when it tried to fetch the packages.

Error during update
A problem occurred during the update. This is usually some sort of
network problem, please check your network connection and retry.

When trying to go to the repositories, it seems they are empty.

Two servers, each has a lacp bond into a Procurve switch. Each server has a "bond1" with two interfaces. IP addresses are statically assigned on both bond1 interfaces.

LACP and bond health looks perfectly fine on both sides (checked on ubuntu side and procurve side).

One server tries to ping the other, and the initial ARP is sent out. It is received by the other side but there's NO response. I tried hard-coding a static arp on the sending side, and unsurprisingly, the ICMP Echo Request is received and also not responded to.

Why would a host ghost incoming traffic?

I've checked all of the following:

sysctl net.ipv4.conf.all.rp_filter

sysctl net.ipv4.conf.default.rp_filter

ip -br addr show

ip link show dev bond1

and even turned off iptables.

No changes.

FWIW, I doubt it's the bond and I doubt it's the switch. The switch DID forward everything it received.

Any suggestions would be welcomed.

I have a hp x2 10-p011nr detachable laptop that I recently revived by installing xubuntu 26.04. The laptop has 2 GB RAM and 32 GB storage so xubuntu seemed to be a good choice for it. I've got all of the hardware up and running with the exception of tablet mode. I can run screen-orientation-manager for manually rotating the screen and onboard for an on screen keyboard (still working on setting that up correctly).

My issue is that I would like to be able to detect when the laptop is in tablet mode and run both of those applications or kill/suspend both apps when the keyboard/touchpad is connected. I'm not sure what the best way to do this is. I've searched around and found some promising info about a libinput script but I also found some info that leads me to believe a udev rule might be the correct method. Can someone give me some guidance? If this issue already has solutions that would be great but just pointing me to where I can learn more about solving it myself would be great too.

On a side note, is there a different ubuntu distro that would be just as lightweight and solve this problem out of the box?

I'm using pycharms to build an apk for a python app. During the process buildozer crahses, I get this error:

All the packages listed here are installed in the python venv. I didn't think the venv i created in pycharms was externally managed, the instructions i found online for how to set one up are what I did to create this environment. Could someone please help me understand what has gone wrong.

I'm a bit of a noob to Ubuntu. I'm turning my old laptop into a media server with Ubuntu Server, and while transferring some files over with sftp i got an error code Failure, which means its got no idea why.

I checked the size of the folder with all the media in it and it only reaches 60GB. Then, using sudo fdisk -l it says I have 3 partitions, one of them being 473GB, but that partition is not listed when using df -h.

Am I being stupid and is my problem not actually storage space, or did I screw something up setting this server up?

Also to make myself clear, I'm not looking for a solution for file transferring, only if my storage is actually full or if it is hiding and I have a different problem. Edit: Outputs you guys requested

Since a v151 Firefox supports Webserial natively. For me this is an long awaited function. But I cannot seem to find any documentation on how to get this running with the installed snap version in Ubuntu (26.04 in my case).

What I tried:

The serial port I wanted to try is popping up in the /dev folder as 'ttyACM0'

I read about webserial with Chromium (snap) where you need to connect the raw-usb to snap. But raw-usb seems not to be available for firefox

# sudo snap connect firefox:raw-usb          
error: snap "firefox" has no plug named "raw-usb"

with:

sudo snap connect chromium:raw-usb

everything works as aspected but I prefer firefox

Is the snap package just not ready (yet) or is there anything else I can try?

I have seen a number of super old questions about this with no answers. I managed to convince my company to let me use Linux, and now I'm having a really hard time using it because the pointer precision on the trackpad is horrible.

There is a setting for mouse acceleration for a regular mouse, but nothing for trackpads. Is this normal?

How can I fix it?

EDIT: It would also be great if there is a way to adjust the scrolling speed/number of lines; it seems that's only a setting for a mouse as well.

I am attempting to install ubuntu v26.04 LTS server edition (the server install image on this page) on a laptop that previously used Windows 10. The laptop is a Lenovo Ideapad (specs here) and is not currently plugged into an ethernet connection. I have followed the instructions on this page, including converting a USB stick into a bootable USB drive with Rufus, configuring the laptop to start from the usb boot device, and most of the install process in that page and this screen-by-screen tutorial. I am on the last step of the install process, where I have clicked through all of the screens that require interaction and the OS is being installed.

Now, the process seems to be stuck on one step labeled "configuring mount: mount-0". The log so far reads this:

It has been stuck here for about 2 hours. When I enter the help menu I see that there is an error report to view with the title "Block device probe failure". When I click on it the message reads "Sorry, there was a problem examining the storage devices on this system". The full error message is very long, but within it I found an asyncio.exceptions.CancelledError. I am not sure how to get the full error message off the device. Any suggestions on how to proceed with this would be appreciated. If it is stuck, is it safe to restart the computer? This page appeared pretty instantly, so I don't think that it did any serious wiping of the system yet (but I am not sure on that).

Thank you!

I run Kubuntu and while updating Ubuntu (some Kubuntu updates require updating the Ubuntu elements via its own software) to 26.04 LTS Racoon sometime ago it said it couldn't update grub-efi[...] then quit the installation while having installed 100% of the update except that one part. I restarted the machine and it was updated like normal. It's running fine as of late (except one easily fixed initram problem) but every time I update anything it says grub-efi and some other files can't be updated.

This is the output while trying to update "grub-efi-amd64-signed", "linux-headers-7.0.0-22-generic", "linux-headers-generic", "linux-generic" and "linux-image-7.0.0-22-generic":

After upgrading from 25.10 to 26.04, my activities overview (the search bar that pops up when pressing the Windows key) forgets all apps on my system. Is this a known issue?

Here is me searching for a "Settings" app shortly after a fresh login:

I have tried clearing various caches, but nothing has helped so far.

Edit: One kind gentleman said I might have mistyped the linux image name. I have input the command again with the spelling checked and it worked fine.

So I boot my computer and it says it's kernel panic time, because it couldn't mount unknown block.

I look up online and it says it's all about that initramfs that could be wrong after an update (which is odd because I booted this machine fine earlier today and didn't update anything) and I should boot into an earlier kernel version to update it. I do that, boot nicely, everything is working but I can't do the initramfs update, it shows this error:

Does Linux Ubuntu 25.10 come with the needed printer drivers for HP Laser Jet M207-M212?

I had a few mess ups while trying to fix my audio and I really think its beyond repair now. If I reinstall the OS will it return me back to the beginning or will stuff stay? I do not care about the files just looking to retry in fixing my audio issues.

The only advice I found online is to configure grub to force ACPI shutdown, but is that a good solution, or will it ruin my system over time?

Is there a better fix for this?

The Markdown Editor application in Gnome Circle named Apostrophe does not start on Ubuntu 26.04. On previous versions of Ubuntu (25.10) it did not have this problem.

$ apt list apostrophe
apostrophe/resolute,resolute,now 3.4-2 all [installed]

The error messages in system log are:

On Ubuntu 24.04.4, with a Brother MFC-L2700DW printer and Proton VPN. I used to be able to print without any issues. Then I started having a problem where, when I initiate a print job, I get system messages every few minutes that say "Printing", but the printer is not doing anything.

Searching around online, I found the suggestion to use systemctl restart cups-browsed which did solve the problem once or twice (maybe with some restarting, I don't remember anymore that was a while ago).

But now I'm trying to print something and getting this "Printing" hang problem and I've tried the above command and restarting and nothing has helped. No idea what to try next. Thanks.

Update: I just tried a new thing which is turning off my Proton VPN. I do not remember exactly when I installed that vs. when this problem began, but maybe it was about the same time! So maybe restarting cups-browsed did nothing, but maybe restarting the computer helped because Proton doesn't come on automatically, so if I restarted and then went straight to printing, the VPN would have been off.

Yes, this is relevant. VPN off, I can print. VPN on, the printing hangs in the way I described above. No restart needed to get printing going again, just turn off the VPN, cancel the job that is hanging, and initiate a new print job and it works. I went back and forth several times.

I am leaving this question active because it would be awesome to be able to just print and not have to worry about thinking about is my VPN on or not. Added VPN to the title and tags.

I recently installed Ubuntu 26.04 on my Acer laptop with Ryzen 240 and RTX5050. There are two problems. First I have some random display glitch occurring for a brief moment every minute or two. Second I can't make Steam use my dGPU for games. I tried NVIDIA X Server Settings and tried to launch Steam with DRI-PRIME=1, but it always runs with iGPU and says inconsistent number for dri prime. What can I do about it?

I'm fighting with this for a week. Read and searched a lot, That's why I decided to post my first question.

Initial setup :

Windows AD Network. Windows DHCP Servers automatically update DNS. Install Ubuntu server on Hyper-V virtual machine. This time I decide to give a shot for 26.04 LTS. Ubuntu server is with static IP address, which I define during installation process. Let's say I gave it name svr-2604 as a host name and IP: 192.168.100.100/24 gateway: 192.168.100.1 Installation went smooth exactly as it was in 24.04 LTS that I used till that moment. After installation I checked IP:192.168.100.100 and it was there. I get terminal SSH and everything was as expected. I create static record in DNS with name svr-2604 pointing to 192.168.100.100 (my usual action). I could ping and connect by terminal to SSh using this name (also as usual).

Restart Ubuntu server and for some reason I flush DNS cache on my computer. At that point I try to connect with terminal using the same name - without success. Check server - running. Ping name - no response but returning address completely different from DHCP range. Check DHCP and figure-out fresh address lease on name svr-2604 with address (let say): 192.168.100.36. IN DNS I have already two records about my server : 192.168.100.36 - dynamic from DHCP 192.168.100.100 - static

On request DNS returns first one and I can't connect to server by name.

On Ubuntu I checked log records :

journalctl | grep -i dhcp

get

svr-2604 systemd-networkd[420]: eth0: DHCPv4 address 192.168.100.36/24, gateway 192.168.100.1 acquired from 192.168.110.XXX (my dhcp server)

Check for configuration in /run/systemd/network and there I get :

-rw-r----- 1 root root             78 May 29 09:41 10-netplan-eth0.link
-rw-r----- 1 root systemd-network 222 May 29 09:41 10-netplan-eth0.network
-rw-r--r-- 1 root root            131 Apr 13 13:34 zzzz-dracut-default.network

First two are clear - result from my static address netplan configuration, but zzzz-dracut-default.network ??

Start digging and figure-out it was dynamic generated from dracut. It's content :

[Match]
Kind=!*
Type=!loopback

[Network]
DHCP=yes

[DHCPv4]
ClientIdentifier=mac
RequestOptions=17

[DHCPv6]
RequestOptions=59 60

In my opinion, this is where my problem comes. dracut on boot process leased address with my server name. When Ubuntu 26.04 boots - it takes configuration from netplan (the one that I wish to) but I finish with two different records in DNS.

What I try is to set dracut to use static address. I ended with idea that I have to give kernel command for this. Create following file : /etc/dracut.conf.d/network.conf

with following content :

kernel_cmdline="ip=192.168.100.100::192.168.100.1:24::eth0:none"

after that I regenerate image with

dracut --force and reboot 

Sadly no result. At that point I gave up and decide to ask for help. This never happens with Ubuntu 24.04 or earlier.

What is may positive move to resolve this problem ?

Any help is appreciate !

Regards

My personal guess is this is due to sssd

I am unable to run Ubuntu properly with my NVIDIA RTX 5050 GPU. Both Ubuntu 24.04 and Ubuntu 26.04 result in a black screen when the NVIDIA driver is enabled. The system only works using nomodeset, but then GPU acceleration is unavailable and resolution is limited (around 720p).

I can only install and boot the system using GRUB modification (nomodeset), but enabling NVIDIA drivers causes a black screen after boot.

I have tested multiple NVIDIA driver versions (570, 580, 595), but all result in the same issue.

System information

• GPU: NVIDIA RTX 5050

• CPU: AMD Ryzen 5 5500

• RAM: 8GB DDR4 3200MHz

• Storage: 256GB NVMe SSD

• Motherboard: Gigabyte B550M-K

Steps already tried

1. Boot with nomodeset (only working method)

At GRUB:

• Press e

• Add:

nomodeset

Then boot with Ctrl + X

2. Install NVIDIA drivers

sudo apt update
sudo apt install nvidia-driver-580

Also tested:

sudo apt install nvidia-driver-570
sudo apt install nvidia-driver-595

3. Remove broken NVIDIA installation (via chroot / recovery)

sudo apt purge '^nvidia'
sudo apt autoremove --purge
sudo rm -f /etc/X11/xorg.conf
sudo rm -f /etc/modprobe.d/nvidia*
sudo update-initramfs -u
sudo update-grub

4. Update kernel / system packages

sudo apt update
sudo apt upgrade
sudo apt install linux-generic-hwe-24.04

Current result

• System boots only with nomodeset

• Without nomodeset, black screen occurs immediately after GRUB

• NVIDIA drivers install successfully but break display on reboot

• No GPU acceleration is working

Request

Looking for a stable solution to run RTX 5050 properly on Ubuntu (kernel/driver configuration fix or compatibility workaround).

I am unable to boot the Live USB of Ubuntu Cinnamon 26.04 on a Dell Optiplex 7050 Micro (Intel HD 630). The boot process hangs indefinitely after "Get:6 file:/cdrom resolute/universe...".

I have tried the following without success:

• Both UEFI (GPT) and Legacy (MBR) boot modes.

• Multiple USB sticks and flashing tools (Rufus, BalenaEtcher, Ventoy).

• Boot parameters: nomodeset, copytoram, pci=nommconf, usbcore.autosuspend=-1.

• Disabling Secure Boot, VT-d, and TPM in BIOS.

Older distros like Peppermint 10 boot perfectly on this exact hardware. There seems to be a major regression in the 26.04 kernel or dracut initialization for this chipset.

This is a major disappointment. I prepared this machine with a brand new M2-disk, and have waited months for the 26:04 to be released. The machine now goes back om the shelf while I wait for a fix. The plan is to test this distro on this machine in hope of that Ubuntu Cinnamon can take over all the machines here running Peppermint 10 Respin (with Ubuntu Pro) - until 2028 max. I can wait longer, but if this isn't fixed by the autumn, I will be very angry and inclined to look somewhere else.

I'm deeply disappointed and utterly broken after hours of trying and failing.

kvm_amd CPU x isn't AMD or Hygon?

This text appear early in the boot sequence.

Now this is not really causing any trouble, RIGHT NOW.
But I consider all similar messages to be a potential hazard to the stability of my machine.
Therefore I quite fiercely hunt them down, and "swat them out".
The more of these unwanted messages you have the greater potential for strange interference and malfunction.

These are apparently about virtualbox:
https://unix.stackexchange.com/questions/798132/why-and-how-were-kvm-modules-unexpectedly-enabled-in-ubuntu-24-04
KVM not supported shown in terminal while it is enabled

... but I have this on intel-based hardware,
an oldish i7-9750H-based Asus G731 laptop, with embedded GTX 1660 Ti.
NOTE: 6 cores+HT, so message does not appear for ALL cores(!?)
Virtualbox 7.2(?) IS installed though, but quite seldom used.

I have:
GRUB_CMDLINE_LINUX_DEFAULT= ... kvm.enable_virt_at_load=0
in /etc/default/grub

No go.

$ sudo -i
# cat >/etc/modprobe.d/kvm.conf
blacklist kvm
blacklist kvm-amd
blacklist kvm-intel

CTRl+D

# update-initramfs -u -k all
update-initramfs: Generating /boot/initrd.img-6.17.0-14-generic
...
# 

CTRl+D again

Reboot... I still get a black screen with these boot messages:

[    6.359851]
[   10.531179] kvm_amd: CPU 4 isn't AMD or Hygon
[   11.104935] kvm_amd: CPU 6 isn't AMD or Hygon
[   11.193682] kvm_amd: CPU 9 isn't AMD or Hygon
_

Still there:

[    6.479793]
[   10.253887] kvm_amd: CPU 9 isn't AMD or Hygon
[   10.901341] kvm_amd: CPU 3 isn't AMD or Hygon
[   10.987984] kvm_amd: CPU 5 isn't AMD or Hygon
_

Those CPU numbers appears to be somewhat random, another run: 0, 8 and 0 (yes, zero repeated) at around 10 seconds.

There has been some apt updates so now with:

$ uname -rv
6.17.0-29-generic #29~24.04.1-Ubuntu SMP PREEMPT_DYNAMIC Mon May 11 10:30:58 UTC 2

Does anyone have any more ideas on how to actually get rid of this?

intel 7265D is not working in any version of ubuntu (from 20.04 to 25.10) while debian 12 doesn't have any issue. i've tried everything adviced by gemini AI. nothing is working.

1. using latest firmware from git.kernel.org
2. using firmware from debian 12
3. adding options iwlwifi 11n_disable=1 power_save=0 to iwlwifi.conf
4. ubuntu reports RAS: soft-offlining pfn while debian 12 is not
5. ubuntu results on sudo iw dev wlp2s0 scan

"scan aborted!"

this is very frustrating. any help is appreciated.

I installed Ubuntu 22.04, and after successfully creating a user name and password, it shows these few lines.

passwd: password updated successfully
Installation successful!
To run a command as administrator (user "root"), use "sudo ".
See "man sudo_root" for details.

I have removed the package vysor in every possible way on ubuntu using

• sudo apt-get remove vysor
• sudo apt-get purge vysor and sudo apt-get --purge vysor and sudo apt-get --purge autoremove
• sudo snap remove vysor
• I see nothing after dpkg --list | grep vysor* but whenever I run sudo apt-get update the languages updates with Ign:23 https://nuts.vysor.io/apt ./ Translation-en always wastes my 10 seconds.

How can I get rid of this?

I am downloading the files in /media. I do have the permission to folders and files, but for each torrent it is giving me this error. Also, I disabled the hiberfile system of Windows so that I can delete or create folders in /media, which changed the Owner of files and folders in /media to root. I then proceeded to edit the /etc/fstab to get the permissions back. After all this, the error is still there. I don't know how to proceed from here.

Qbitorrent version - 4.1.1 File system - NTFS OS - Ubuntu 18.04

Trying to run rtklib on ubuntu 16.04.2 and getting this

$ ./rtkplot_qt: error while loading shared libraries: libQt5WebEngineWidgets.so.5: cannot open shared object file: No such file or directory

I'm guessing I need to install libqt5? If so how to install it can someone give me some instruction?

I have the newest release of Ubuntu 12.04 and Windows Server 2008 R2. On the Windows Server I have a device management agent which keeps track of all the devices in the local area network as well as any information of these devices and alerts sent from these devices. I am trying to enable and setup SNMP on the Ubuntu desktop. It is a virtual machine in Virtual Box. I know on a Windows 7 desktop you need to set it up so that it accepts SNMP packets from the Windows Server as well as set up a community name (i.e. private/public) with a trap destination of the Windows Server. How do I go about this in Ubuntu?
