SUMMARY If I open a tab in dolphin and set the location to admin:/tmp/foo, polkit prompts me for a password and now I have root permissions in /tmp/foo, great! Shortly afterwards, it suddenly 'kicks me out', and I see the message that Administrator rights have expired. Subsequent attempts to gain admin rights immediately 'kick me out' again. Looking at the journal, I can see that polkitd is crashing due to exceeding the open files limit, which is at the default. This started happening a couple of months back back was working prior to that. STEPS TO REPRODUCE 1. Open dolphin and browse to some folder you'd like to have root in 2. prefix location with "admin:" and press enter 3. Fill password prompt 4. Use for a short time OBSERVED RESULT polikitd crash EXPECTED RESULT no polkitd crash SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20251229 KDE Plasma Version: 6.5.4 KDE Frameworks Version: 6.21.0 Qt Version: 6.10.1 Kernel Version: 6.18.2-1-default (64-bit) Graphics Platform: Wayland Processors: 24 × AMD Ryzen 9 5900X 12-Core Processor Memory: 32 GiB of RAM (30.7 GiB usable) Graphics Processor: NVIDIA GeForce RTX 3090 Happy New Year!
Thanks for the crash report. As the message at the top of the summary says, if something crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the coredumpctl command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl ? Thanks.
I reported this because I'd seen others effected by it, so I presumed you'd be able to reproduce...
