WHAT SHOULD I DO

I've been experiencing a few problems with updates failing.
I tried running sudo apt --fix-broken install and that gives the following output:

Anyone?

Thanks.

I am not able to connect to port 443 at api.snapcraft.io since today. However port 80 works. Since port 443 is not accessible I cannot "refresh" my snaps:

I have some virtual servers around the world and all work with no problem.

However, I have tried with two different ISP's in my location (Turkey) and both have the problem I described above.

Is it a general problem? Are any other snap users around the world facing the same problem?

when I turn my pc (tower HP)to sleeping mode I have the fans of the graphic card going noisy, then black screen and total freeze. Nothing to do but reboot. Graphic Card : GTX1060 driver 580.142 . I tried to install driver 535 with no effect. I also tried with no Nvidia driver an then sleeping mode is OK but not satisfying situation. This points clearly a Nvidia/Wayland driver Issue I guess. Any idea ? (I'm now with 580 driver)

Good morning all, I'm running Ubuntu 2404 and since yesterday I'm getting an error while searching for apps in Applets. It states there's no internet connection but everything else like web browser, mail et works. I have stopped VPN to no avail.

Any suggestions?

When working in a Ubuntu 26.04, the system suddenly freezes and none of the keys on the keyboard or mouse work

Is it known whether the recent attacks (see Ubuntu Infrastructure not responding, returning 503 or other errors) on the whole Ubuntu infrastructure (official Websites/snapcraft/Launchpad) cause any security risk in computers running Ubuntu?

What I know so far.

1. When I start streaming on discord using the desktop app it stops streaming a less than a second after starting it.

2. I have attempted to stream using the browser and that does work. But I would rather not have to join on the browser every time I have to stream.

3. I have followed some other advice here and found out that I am on Wayland (not sure what that means) and that I should want to be on X11. But when I have attempted to go into the config file to change it the comment #waylandenabled = false is nowhere to be seen. And the config file isn't that long so I can't be missing it.

I attempted to add in waylandenabled = false into the config under [daemon], then I saved and exited the config. I believe after I hit enter it caused me to reset my computer or at least made me log out again.

After that discord still isn't streaming so I'm not sure what to do next exactly.

I have mostly been looking at this here Im having issues with screen sharing in Discord on Ubuntu

and attempting to use the AI assistant tool.

I am using Ubuntu 26.04 LTS

I have a MacBook Air that I want to use as a small home server (Casa OS was recommended). The issue is that I can't see the Ubuntu Server installation screens, because the MacBook's screen is dead. I troubleshot it, and there's no way to make it work without a pricey repair. When macOS is fully booted I can use an external screen to interact with it, but this screen does not display images during booting which means if I were to put Ubuntu Server on it I'd have to do it blindly. Has anybody ran into a similar problem or know how to help?

After updating to 26.04, the icons in the app grid got significally smaller and the padding seems a bit off, especially on very wide monitors..

How can I "restore" or fix the app grid without using extensions?

Hi just had my pc redone the girl put Linsux on it I am unfamiliar with it it didnt down load a microphone

I tried installation of both server and desktop installations today, both as VMs on Hyper-V. The experience couldn´t be more different. I suspect it is because the installation is also a live experience, but comparing the two looks really strange to me, with all those duplications and differences.

Two examples:

the desktop installation supports use of TPM for FDE, whereas the server installation does not. Neither supports Clevis & Tang, which would make sense in an enterprise environment.

also, the desktop installation supports active directory integration, whereas the server install does not. As I am running mostly server installs, I´d appreciate if active directory integration would be an installation option.

I also encountered two (supposed) bugs:

For the desktop with TPM test I activated the virtual TPM of Hyper-V. Windows 11 runs fine with that. Ubuntu 26.04 install complains with the following:

error with TPM2 devices: TPM2 device is present but is not a PC-Client TPM

Does it matter at all, whether it is a PC-Client TPM or not?

The other is that I activated active directory during installation, but couldn´t login using active directory. How can I analyze the reason for that?

I have tried to visit the official Ubuntu website, but it seems to fail with 503. Can anyone share any information they might know about this issue?

I've been having trouble getting Multipass to run Ubuntu instances on Apple Silicon M2 and M3.

The problem, at launch, is:

[2026-04-30T16:33:59.021] [error] [pluto] process error occurred Crashed program: qemu-system-aarch64; error: Process crashed

• macOS 26.4.1 25E253

• Apple MacBook Air M5

I have tried all sorts of things: uninstalling, installing with brew from source, and using the qemu version from ports.

This has been going on for a few days now. My computer did a major update, and after that my computer struggles with Skyrim LE even though it had no issue at all before that. The spikes mainly happen during combat, particularly dragon fights, making the game nigh impossible to play. Even simply walking around is grueling because of the lag spikes.

I tried to change my emulator to proton 10 ge from proton 8 ge, but that only made my game run worse. I tried to revert to the last version, but that just made my computer freeze. I did this through the menu that comes up if you press esc during start up. Its the same menu that appears after a major update at times. I selected version 5, but as stated that didn't end well. I even reinstalled my graphics driver, but that made no difference at all either.

I'm at a loss as to what else to do. I can't continue my playthrough because my game is now practically unplayable even though it was fine just before. I was hoping another update would fix this after people complained, but nothing has happened other than updates for something called iproute2. I can't even find an option on my comp to issue a report about the problem I'm having.

What else can I do here?

And no, my steam is NOT installed through snap. I learned that the hard way when I first installed ubuntu years ago.

update: Well, I got another major update. It both updated the kernal, and some of the updates even named my graphics card driver. After that, my game runs like it did before, perhaps better even. I'd still like to know what happened. Version right now is showing Ubuntu 22.0.4.5 LTS. Graphics driver is nvidia 580. And yes, I know that's not the most up to date version, I had to set it to that to keep firefox from crashing on me randomly. It had no impact on my games fortunately enough.

i did some basic tweak for supressing the Wayland Display, but could not set to x11.

Can someone post how i can disable Wayland and continue on X11 i haev some apps that dont support Wayland.

For example wmctrl and onboard don't work for me with Wayland. So if you really need one of these or some other tool, that needs x11, then I suggest that you try with Lubuntu or Xubuntu or some other flavor of Ubuntu, that is still using x11. You can try these flavors live (booted from USB without installing) before you decide what to use. But several tools work with Wayland now, and there are might be alternatives for some of your old favorites, alternatives that work in Wayland.

We are running a bunch of containers for a cyber security teaching environment, where students can execute arbitrary commands (unprivileged).

Our system (Ubuntu 24.04.4 LTS) is affected by the recently-published "Copy Fail" vulnerability (CVE-2026-31431).

Unfortunately, updating did not produce any new kernel packages, and we are still stuck with 6.8.0-110:

# uname -a
Linux teaching-host 6.8.0-110-generic #110-Ubuntu SMP PREEMPT_DYNAMIC Thu Mar 19 15:09:20 UTC 2026 x86_64 x86_64 x86_64 GNU/Linux

PoC exploit (makes su not ask for passwords until reboot):

uid=0(root) gid=1000(user) groups=1000(user),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),101(lxd),988(docker)

How can we harden our system until an official patch package becomes available?

NONE of the AppImages work

I'm using 26.04 LTS.

I'm using AppImage with a lot of applications.

None of them work. I installed Fuse, and only one works; the rest don't. They say this.

I am experiencing severe lag and intermittent freezing after resuming my laptop from suspend on Ubuntu 26.04 (Resolute). The system becomes almost unresponsive for a period of time or requires a hard reboot.

My System Specs:

• OS: Ubuntu 26.04 LTS (Development Branch)

• Kernel: 7.0.0-14-generic

• CPU: AMD Ryzen 5 4600H with Radeon Graphics

• GPU: NVIDIA GeForce GTX 1650 (Laptop)

• Driver Version: 580.142

• Display Server: Wayland

• RAM: 32GB

What I have tried so far:

1. Disabled the following NVIDIA systemd services to see if it bypasses the hang during resume:

   • nvidia-suspend.service

   • nvidia-hibernate.service

   • nvidia-resume.service

2. Verified that nvidia-persistenced is active (running).

3. Updated GRUB and checked the memory sleep state.

Observations:

• I am running a hybrid graphics setup (AMD + NVIDIA) on Wayland.

• The issue persists even with the 580.x and 590.x driver series.

Question:
Has anyone encountered similar freezing issues with the 7.0 kernel and NVIDIA 580 drivers? Is there any way to fix this issue?

I used Obsidian software on ubuntu 25.10. I did a test before production with 26.04. I install obsidian just after installing os; obsidian is ok; I reboot ubuntu and obsidian does nothin when I launch it; do you have an idea?

I am trying to use an HP LaserJet 1018 on Ubuntu 24.04 with HPLIP installed, but the printer does not actually print despite being detected.

Why is the printer detected but not able to communicate or print, and how can this be fixed on Ubuntu 24.04? How to set up HP Laser 1018 printer properly on Ubuntu?

After upgrading from Ubuntu 24.10 to 25.04, I noticed that WireGuard does not start. Investigating the problem I found the following error message in system log:

May 15 17:09:31 ocasrv wg-quick[14511]: [#] /etc/wireguard/helper/log-info.sh startdate
May 15 17:09:31 ocasrv wg-quick[14521]: /usr/bin/wg-quick: /etc/wireguard/helper/log-info.sh: /bin/bash: bad interpreter: Permission denied
May 15 17:09:31 ocasrv wg-quick[14523]: Unable to access interface: No such device

Here log-info.sh is my custom script that ran without problems in the previous version of Ubuntu.

I checked the system-provided /usr/bin/wg-quick and it is exactly the same as in the previous version of Ubuntu.

However, I see the following errors also:

[ 2875.720653] audit: type=1400 audit(1747318171.354:3330): apparmor="DENIED" operation="open" class="file" profile="wg-quick" name="/etc/nsswitch.conf" pid=14511 comm="wg-quick" requested_mask="r" denied_mask="r" fsuid=0 ouid=0

Checking the /etc/apparmor.d/ directory, I noticed two new files named wg and wg-quick. These files were not present in the previous versions of Ubuntu.

ChatGPT recommended this:

# ln -s /etc/apparmor.d/wg-quick /etc/apparmor.d/disable/
# ln -s /etc/apparmor.d/wg /etc/apparmor.d/disable/
# apparmor_parser -R /etc/apparmor.d/wg-quick
# apparmor_parser -R /etc/apparmor.d/wg
# systemctl reload apparmor

which solves the problem.

However, what is the recommended action? Is this a new bug?

I installed Ubuntu 22.04 and I setup the interface my server has with an IP and DNS servers that it is supposed to use:

root@m15jumplnxnoc01v:/# cat /etc/netplan/00-installer-config.yaml
network:
  ethernets:
    ens160:
      dhcp4: no
      addresses:
        - 10.248.0.235/24
      routes:
        - to: default
          via: 10.248.0.1
      nameservers:
        addresses:
          - 10.248.0.100
          - 10.248.0.103

  version: 2

After getting the interface configured and working, I confirmed that I was able to ping 8.8.8.8, but I couldn't get nslookup to resolve www.google.com

So I went ahead and added the DNS servers globally by adding them to the file /etc/systemd/resolved.conf and restarting the service:

[Resolve]
DNS=10.248.0.100 10.248.0.103
FallbackDNS=8.8.8.8
Domains=~.
#DNSSEC=no
#DNSOverTLS=no
#MulticastDNS=no
#LLMNR=no
#Cache=no-negative
#CacheFromLocalhost=no
#DNSStubListener=yes
#DNSStubListenerExtra=
#ReadEtcHosts=yes
#ResolveUnicastSingleLabel=no

That didn't resolve my problem, although I was able to see both the global and interface DNS servers properly set:

root@m15jumplnxnoc01v:/# resolvectl
Global
           Protocols: -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported
    resolv.conf mode: stub
  Current DNS Server: 10.248.0.103
         DNS Servers: 10.248.0.100 10.248.0.103
Fallback DNS Servers: 8.8.8.8
          DNS Domain: ~.

Link 2 (ens160)
    Current Scopes: DNS
         Protocols: +DefaultRoute +LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported
Current DNS Server: 10.248.0.100
       DNS Servers: 10.248.0.100 10.248.0.103

But I'm still getting an error reporting "time outs" to the DNS servers:

root@m15jumplnxnoc01v:/# nslookup www.google.com
;; communications error to 127.0.0.53#53: timed out
;; communications error to 127.0.0.53#53: timed out
;; communications error to 127.0.0.53#53: timed out
;; no servers could be reached

The interesting things is that the connectivity is indeed in place:

root@m15jumplnxnoc01v:/# nc -uvz 172.0.0.53 53
Connection to 172.0.0.53 53 port [udp/domain] succeeded!

root@m15jumplnxnoc01v:/# nc -uvz 10.248.0.100 53

root@m15jumplnxnoc01v:/# nc -uvz 8.8.8.8 53
Connection to 8.8.8.8 53 port [udp/domain] succeeded!

I did a tcpdump looking for UDP/53 traffic, and I do see the requests going to the right servers:

I even tried changing the DNS service to resolvconf and editing the config file /etc/resolvconf/resolv.conf.d/head to add the DNS servers there, and dnsmasq and adding the DNS serves to /etc/resolv.conf (which is what dnsmasq uses).

No matter which service I try or how I configure it it keeps timing out, but the connectivity is definitely there as shown above.

Any idea on what else can I check?

Thanks in advance!

I run Ubuntu 22.04 LTS with Remote Desktop that is built in and it is great! (see attached image) However, when my internet connection breaks the service seems to hang up and I need to reboot the computer in order to be able to connect again. The normal sshd always works even after a connection issue so I wonder how do I: Reset this service from command line?

It seems to me that just resetting it will work but I don't know what service it is... Thanks for any suggestion :-)

I'm new to linux, so sorry for my little knowledge in advance. Intel AX201 wifi adapter doesn't seem to work properly for me on Ubuntu 22.10. It didn't work so good with windows 10/11 too. Disconnects randomly and I can't get it working again; but when I reboot,it sometimes works for 10 minutes or so and then goes away again. what info should I provide to be able to get any help?

I have a Kubernetes cluster. I want to find opportunities to contribute to scientific efforts with the compute and memory resources I have available.

I am interested in providing resources for

• math research
• cancer research
• SETI
• and more

Please advise with any recommended

• helm charts
• operators
• manifests

I am especially interested in ones that display performance information to see if the cluster is offering value to the efforts.

Thanks!

I'm searching for a good, simple PDF viewer without javascript support. This link says that Evince does not have javascript support but may in future.

I want a PDF viewer that has no javascript support now and in thefuture. Is Atril the MATE default PDF viewer a good choice? The reason I want this is to avoid PDF JavaScript exploits.

Is there any way that I could use my old Android device by connecting it via USB or even using the wireless LAN and make/receive calls and traditional text messages (SMS) on my laptop running Ubuntu?
