The firmware package is not installing.

dpkg-deb (subprocess): decompressing archive '/var/cache/apt/archives/linux-firmware_20240318.git3b128b60-0ubuntu2.4_amd64.deb' (size=483854410)
member 'data.tar': zstd error: Data corruption detected

I have tried forcing a re-install and re-downloading the package and the error still occurs. How do I fix this. Full command output below:

After upgrading from Ubuntu 22.04 to Ubuntu 24.04, I had to reinstall Inkscape, which for some reason was removed during the upgrade. I've tried three methods to install, none of them fully successful:

1. sudo apt install inkscape => Result: inkscape does not launch (segmentation fault, probably LP bug #2079921)
2. sudo add-apt-repository ppa:inkscape.dev/stable && sudo apt install inkscape => Result: inkscape does not launch (segmentation fault, same bug as above?)
3. sudo snap install inkscape => Result: inkscape launches (yay!). But it cannot export files (exporting to PDF was my main use case). The widget to select a file name to export does not work in the snap package, it does nothing upon clicking on it. And without a file name, the export throws an error. Same as Inkscape snap package unable to export png.

How do people use Inkscape in Ubuntu 24.04 at all? What are the next steps? Flatpak? Build from source?

Notes:

1. I've noticed there is an additional ppa:inkscape.dev/stable-daily but the fact that this supposedly daily PPA hasn't been updated for the last 4 months makes me think it's no longer maintained either.
2. I've read bug reports about Inkscape crashing in Wayland with some tablets. I've disconnected my tablet, with the same result (crash).

I have a Dell Inc. XPS 13 7390 notebook with Ubuntu from the year 2020 with an Intel Rivet Killer AX1650W Wireless module supported by Linux and the following specs:

On older Ubuntu LTS the wireless worked but since I upgraded to Ubuntu 24.04.1 LTS I can view but cannot connect to the SSID.

Further Info

• My Network Adapter is detected by Ubuntu 24.04.1 LTS and I can connect to SSID in the BIOS.
• My router should be OK, because other devices (Android, Windows 11) can connect. I can give further details if necessary.
• After starting the notebook, I have no internet access through wireless and no internet access trough Ethernet. I need to run $ sudo dhcpcd to connect to the internet via Ethernet.

no interfaces have a carrier

• Immediately without internet access i get informed that software updates were installed, so there might be some loop? Overview of installed firmware and system updates details for system updates (actually downgrades (sic!)

It seems that my network interfaces were changed. Might that cause problems?

There are posts from others with similar issues, but I didn't find any solutions that worked for me.

I recently set up a virtual server on Oracle Cloud using Ubuntu. I wanted to enhance security by changing the default SSH login port from 22 to 777 (or any random port). So, I went into /etc/ssh/sshd_config and changed the Port 22 setting. Now, I’m unable to log back in via SSH, whether I try using the new port or the old one.

So can't use any commands... only the dashboard... which is a struggle in itself.

I’m using PuTTY for SSH access and have already contacted Oracle Cloud support. Unfortunately, their response was... unhelpful/useless/waste of time(to put it mildly) — they essentially just pointed me to basic Google search results, which I had already tried without success.

Has anyone else experienced this issue on Oracle Cloud’s free tier, or does anyone have advice on how to fix this? I didn’t take a backup (I know, my mistake, already feeling beyond stupid), and I really need to recover some important data from the server. Any suggestions would be greatly appreciated!

I've tried all kinds of things and the Yubikey Manager still shows up in my launcher.

I've tried sudo apt-get autoremove yubikey-manager

I've tried uninstalled from software manager.

It's still in the launcher. The manager never discovered my key, so I just want to delete it.
