Neon plasma 6.0 pkcon update fatal error

I had been updating 6.0 since RC1, and all was good. Then I started getting an update failure:

Fatal error: Error while installing package: trying to overwrite ‘/usr/share/applications/kde-mimeapps.list’, which is also in package neon-settings-2 0.4+p22.04+vstable+git20240125.1041

I reported that bug, but it was not fixed after a ~week, so I do a fresh install.
Fresh install, immediately go to update, and get:

Fatal error: Error while installing package: trying to overwrite ‘/usr/share/applications/kde-mimeapps.list’, which is also in package neon-settings-2 0.4+p22.04+vstable+git20240125.10410215.0414-0.amd64

I guess stop using RC and wait till March for release?

Testing or Unstable? Can you link to the bug report?

Use Apt to update, or look at /var/log/apt/term.log

Look for the full error that mentions which package trying to overwrite things.
It probably looks like this:

error processing archive /var/cache/apt/archives/plasma-desktop_4%3a5.91.90+p22.04+vstable+git20240214.0239-0_amd64.deb (--unpack):
 trying to overwrite '/usr/share/applications/kde-mimeapps.list', which is also in package neon-settings-2 0.4+p22.04+vstable+git20240125.1041

It gives enough info to be able to fix it:

sudo dpkg -i --force-overwrite /var/cache/apt/archives/plasma-desktop_4%3a5.91.90+p22.04+vstable+git20240214.0239-0_amd64.deb

Use the full path to the file you find in your errors, not necessarily what I have shown, in case it is something different. You say yours is from a week ago, but this popped up up for me on the 14th on my daily driven testing install.

As a …testing… platform using git-release code and automated build systems sometimes you gotta use a little apt and dpkg foo once in a while. We will unfortunately find little bits that need to be looked at before things are ready for official release and official packaging for neon.

Thanks for your help!

I’ll try your fixes and report back!

FIXED! Thanks. I think I’d nibbled all around the fix, including running dpkg -i on the .deb, but without the --force option. :slight_smile:

Yesterday after updating I had the same problem, but with several packages. To fix it run ‘pkcon update -v’ for verbose output. Where the program aborts with an error, look at the problematic package and install it manually: ‘dpg -i --force-overwrite <path to apt cache/package name>’.
