Broken install on neon update

Hello,

I am trying to an upgrade on an MS Surface (been working great with plasma 5 for the last couple of years) but I have a completely broken upgrade currently. I don’t know if this is a bug or dependency hell.

When performing the upgrade it fails with:

Fatal error: Error while installing package: trying to overwrite ‘/usr/share/doc/HTML/ca/kcontrol/cursortheme/index.cache.bz2’, which is also in package plasma-desktop-data 4

Nothing in my linux fu has helped, ‘pkcon update’ fails. ‘apt --fix-broken install’ fails (both fail on the exact same file)

Any pointers to fixing this?

Thanks

You can try the command (you will need to enter your password) in konsole:

sudo pkcon install libdecor-0-0 libsdl2-2.0-0 plasma-desktop plasma-desktop-data --allow-reinstall

I’m really sorry this happened. There has been some packaging issues in Neon. And neon maintainers are very conscious of the issue.

No good


sudo pkcon install libdecor-0-0 libsdl2-2.0-0 plasma-desktop plasma-desktop-data --allow-reinstall

I also tried option 1, same error

You can try, it might be better:

This also fails early on:

You might want to run ‘apt --fix-broken install’ to correct these.
The following packages have unmet dependencies:

Through selective use of dpkg I was able to get KDE uninstalled and I think I am out of dependency hell.

What package should I be installing to get KDE back?

neon-dekstop?
plasma-desktop?

Don’t forget to sudo apt update before trying stuff. Might be worse retrying, the previous solutions if you hadn’t.

You got:

 dpkg: error processing archive /var/cache/apt/archives/plasma-workspace_4%3a6.0.0-1xneon+22.04+jammy+release+build70_amd64.deb (–unpack):

So uninstall manually plasma-desktop-data before retrying previous solution might unlock sudo apt autoremove and the rest.

Installing both would be preferable.
apt show neon-desktop
apt show plasma-desktop
Should help you decide.

I rebooted, made sure apt looked clean before:

sudo apt install neon-desktop plasma-desktop

During the installation, I received what appears to be the same error:

However, I was able to successfully run the command
sudo apt --fix-broken install

I then reissued the command

sudo apt install neon-desktop plasma-desktop

The installation was completed without errors, and the desktop started normally. Great!


I didn’t document all of the packages I removed with dpkg, however, I started with trying to remove “plasma-desktop” and “plasma-workspace” and removing dependencies that cropped up.

I found myself with a similar problem after trying to upgrade to Plasma 6 - the computer booted to a black screen with a cursor, no login box, and when trying anything apt-related, the error message Fatal error: Error while installing package: trying to overwrite ‘/usr/share/doc/HTML/ca/kcontrol/cursortheme/index.cache.bz2’, which is also in package plasma-desktop-data 4 was produced.

My computer had been running Neon + Plasma 5 before the failed upgrade.

I seem to have fixed things by removing entire neon-desktop, plasma-desktop, plasma-workspace and plasma-workspace-data using dpkg:

dpkg -r neon-desktop
dpkg -r plasma-desktop
dpkg -r plasma-workspace
dpkg -r plasma-workspace-data

Then installing a specific plasma-workspace version (the version string was copied from another working computer):

apt install plasma-workspace=4:6.1.2-0xneon+22.04+jammy+release+build100

After this, apt update, pkcon refresh and pkcon update started working normally again and pkcon update even seems to have reinstalled the neon-desktop and plasma-desktop packages.

Finally, I did a cleanup using apt autoremove and rebooted. The system managed to boot into full GUI just fine. Hope this helps any poor souls stuck on the same problem.

Thank you @madmaxoft! You are my hero. I was struggling with this for many hours now.

My approach:

I followed your post (see the post above this one).

I got the error message when executing sudo pkcon update:
Fatal error: rror while installing package: trying to overwrite '/user/share/sddm/themes/breeze/background.wmp', which is also in package sddm-theme-breeze 4

I asked ChatGPT and executed:
2. Remove the Conflicting Package
If the sddm-theme-breeze package is not necessary, you can remove it before reinstalling breeze:

sudo apt remove --purge sddm-theme-breeze

3. Reinstall breeze
Now, try reinstalling the breeze package:

sudo apt install --reinstall breeze

Finally, I executed sudo pkcon update again and it worked.

I closed with apt autoremove and rebooted, as stated by you.

Just letting people know that I used the above method to fix this problem:

“the current theme cannot be loaded due to the errors below”

I used sudo with

dpkg -r neon-desktop
dpkg -r plasma-desktop
dpkg -r plasma-workspace
dpkg -r plasma-workspace-data

I may have deleted some other items.

Then:

sudo apt remove --purge sddm-theme-breeze

and

sudo apt install --reinstall breeze

Finally:

sudo apt-get update && full-upgrade
