bluelupo:
How did you do that?
I did that in Discover by unchecking the checkbox next to the linux-firmware entry but keeping all other packages selected.
Essentially the opposite of choosing “Select None” and then selecting only a single package.
I use the latter a lot when updating only selected packages during the week so I can defer system updated to the weekend

I’m experiencing the same issue.

I am getting the above error with the current KDE neon user version.

You can either edit the archive.ubuntu.com part of /etc/apt/sources.list.d/ubuntu.sources file (or /etc/apt/sources.list), or install Kubuntu/Lubuntu’s Software Sources utility — software-properties-qt — and running that with sudo.
I’m experiencing the issue too and what I did at the command line was to “hold” the package so that it keeps it at the current version.
sudo apt-mark hold linux-firmware
And then I can update everything else. When I want to unhold that package, I just reverse it with:
sudo apt-mark unhold linux-firmware
sudo apt update

Hi community,
I was able to update the linux-firmware package this morning via the command line. It still took about 10 minutes, but the update finally went through.
Greetings

The problem is still ongoing. If the KDE neon version is dead, let’s know. Let’s not waste our time.

Yes, I too have been having the same issue.
Package download failed:
E: noble-security/main amd64 linux-firmware amd64 20240318.git3b128b60-0ubuntu2.17 is not (yet) available (500 Internal Server Error [IP: 185.125.190.81 80])
The 3rd day. I think the issue is that the server I’m connecting too is down or too slow.

Workaround:
The following worked for me on the console.
Set the linux-firmware package to “hold.”
$ sudo apt-mark hold linux-firmware
Check that the package is on hold:
$ sudo apt-mark showhold
In the meantime, you can update all other packages with Discover, as only the linux-firmware package is blocking the update.
Then set the linux-firmware package back to “unhold” with:
$ sudo apt-mark unhold linux-firmware
The linux-firmware package still cannot be updated as long as Ubuntu has problems with it, but at least everything else can be updated.

I have successfully upgraded Linux Mint – including this “linux-firmware” – but could not upgrade Kubuntu.
Happily, I had documented sources / mirrors for both distros:
-------------------
KDE Neon - sources:
-------------------
$ cat /etc/apt/* | grep http
deb http://archive.ubuntu.com/ubuntu/ noble main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu/ noble-security main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ noble-updates main restricted universe multiverse
$ cat /etc/apt/sources.list.d/* | grep http
deb [arch=amd64] https://dl.google.com/linux/chrome/deb/ stable main
URIs: http://archive.neon.kde.org/user
URIs: https://packages.mozilla.org/apt
----------------------
Kubuntu LTS - sources:
----------------------
$ cat /etc/apt/sources.list.d/* | grep -A 2 http
deb [arch=amd64] https://dl.google.com/linux/chrome/deb/ stable main

URIs: http://archive.ubuntu.com/ubuntu

Components: main universe restricted multiverse

URIs: http://security.ubuntu.com/ubuntu/
Suites: noble-security

---------------------
Linux Mint - sources:
---------------------
$ cat etc/apt/sources.list.d/* | grep http
deb [arch=amd64] https://dl.google.com/linux/chrome/deb/ stable main
deb https://mint-packages.c3sl.ufpr.br xia main upstream import backport
deb http://ubuntu.c3sl.ufpr.br/ubuntu noble main restricted universe multiverse

deb http://ubuntu.c3sl.ufpr.br/ubuntu noble-backports main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu/ noble-security main restricted universe multiverse
So, I can see that ubuntu.c3sl.ufpr.br worked – but archive.ubuntu.com did not.
it’s probably better to just wait for your server to be up or find a sever that is working… i found one in vietnam.
marking something as held and then forgetting about it is a real possibility and not worth the risk.

Hi,
The problem seems to be solved.
