Bug 394595

Application: plasma-discover (5.12.4)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-20-generic x86_64
Distribution: Ubuntu 18.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

I wanted to see if updates existed with muon but errors occured with : /var/lib/apt/lists/fr.archive.ubuntu.com_ubuntu_dists_bionic_universe_i18n_Translation-fr. Then i commented universe and plasma-discover told me about updates avalaible (kernel) then i did updates but after that (no reboot yet) i wanted to tweak plasma-discover (i'm not sure what i've done) but i wanted to install synaptic or something like that ! But i think too many errors with muon and its sources lists. I don't know what to tell you about that (?)

-- Backtrace:
Application: Découvrir (plasma-discover), signal: Segmentation fault
