Bug ID: 400560
Summary: Muon Discover Updates hangs and refuses to allow
logout / reboot
Product: plasmashell
Version: 5.12.6
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: def_morna...@hotmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.12.6)
Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-38-generic x86_64
Distribution: Ubuntu 18.04.1 LTS
-- Information about the crash:
- What I was doing when the application crashed:
I noticed that the Updates icon had the blue dot for new updates.
Since the app routinely takes forever on my aging Dell Optiplex 360, I opened a
terminal window and tried to run "sudo apt upgrade". I was told the package
system was locked, waited, was told that again, decided to use the GUI app.
I am at a breakpoint in my workday and have decided to reboot. Plasma refused,
which generated the crash I am now reporting on.
- Unusual behavior I noticed:
That app has been sitting open ever since (about six hours ago) and is hanging
with no progress indicated on the 14 upgrades. If I try to close the app, I get
a message "cannot close, tasks remain to be done".
I am at a breakpoint in my workday and have decided to reboot. Plasma refused,
which generated the crash I am now reporting on.
I have a fully operating system for now. I just went back to the terminal, ran
"sudo apt upgrade", and got the following:
