Bug ID: 510703
Summary: Automatic shutdown after updates feature crashes
Discover ("arguments to %s() were incorrect, assertion
\"%s\" failed in file %s line %d")
Classification: Applications
Product: Discover
Version First 6.5.80
Reported In:
Platform: KDE Linux
OS: Linux
Status: REPORTED
Keywords: regression
Severity: crash
Priority: NOR
Component: Updates
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: ---
SOFTWARE/OS VERSIONS
Operating System: KDE Linux 2025-10-16
KDE Plasma Version: 6.5.80
KDE Frameworks Version: 6.20.0
Qt Version: 6.10.0
Kernel Version: 6.17.2-arch1-1 (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 7840U w/ Radeon™ 780M Graphics
Memory: 16 GiB of RAM (14.9 GiB usable)
Graphics Processor: AMD Radeon 780M Graphics
STEPS TO REPRODUCE
1. Install available updates
2. While the updates are installing turn on the "after updating: shut down"
feature
3. Wait for updates to complete
OBSERVED RESULT
Instead of shutting down the system, Discover crashes. This is 100%
reproducible for me with today's git master as well as yesterday's. This is a
recent regression. Backtrace:
