I'm having an issue with plasmashell crashing anytime I leave the computer alone for more than an hour or two. I've tried installing debugging symbols to generate a useful crash report, but keep getting told I'm missing the symbols for '/usr/bin/plasmashell'. I installed the package 'plasma-workspace-dbgsym', so I'm curious why I still don't have the debug symbols and where to get them?

Operating System: Kubuntu 19.04
KDE Plasma Version: 5.15.4
KDE Frameworks Version: 5.56.0
Qt Version: 5.12.2
Kernel Version: 5.0.0-13-generic
OS Type: 64-bit
Processors: 12 × AMD Ryzen 5 1600 Six-Core Processor
Memory: 15.7 GiB of RAM

I followed the directions here: https://wiki.kubuntu.org/DebuggingProgramCrash to manually install debug symbols for the various libraries the crash handler said I was missing, including 'plasma-workspace-dbgsym'. However, the crash handler still says I am missing symbols for '/usr/bin/plasmashell', even though dpkg -S '/usr/bin/plasmashell' shows that plasma-workspace is the package for plasmashell.

Output of apt-cache and apt show:

The details from the crash handler (note the ?? for missing symbols): https://pastebin.com/9RB4ZDgZ.

If I click on the "list of files" link in the crash handler to see what packages need to be installed, only '/usr/bin/plasmashell' is now listed.

  • Re. "I've tried installing debugging symbols to generate a useful crash report, but keep getting told I'm missing the symbols for '/usr/bin/plasmashell'." Can you clarify what exactly you try and what exactly the system reports? If you are doing this via the terminal, please copy/paste the output here by editing your question using markdown formatting. – DK Bose May 15 at 1:47

Well, apparently the missing debug symbols has been a confirmed bug for almost 2 years now (see bug #1701788). Would be nice if it could be fixed....
