Description krzmbrzl 2021-04-30 06:11:31 UTC

SUMMARY
Given that Discover now forces me to perform offline-updates, I wanted to install updates via apt upgrade which told me to use pkcon update instead.

Using that however has about a 30-50% chance of getting stuck during the process. It usually happens during the "Running" phase were it will just hang in there indefinitely (until I Ctrl+C out of it).
Every once in a while it also gets stuck in the "Installing" phase (usually around 80%). Ctrl+C'ing out of it and then re-running pkcon update then reports that there are no packages that need updating which kinda suggests to me that it is only the "UI" that gets stuck while the update has completed in the background.

STEPS TO REPRODUCE
1. Run pkcon update
2. See that it gets stuck

I have noticed that usually in cases where pkcon gets stuck, executing it with elevated permissions from the beginning seems to somewhat reliably fix the issue of it getting stuck. I have not yet experienced that sudo pkcon update got stuck.

Note however that I got prompted for the sudo password every time I ran only pkcon update.

Okay it seems that recently this does no longer happen. Until it re-surfaces, I'll close this report.

Comment 3 krzmbrzl 2021-05-19 07:30:31 UTC

I have to revise that. Today it hung again

Comment 4 Ricky Kresslein 2021-05-21 17:12:39 UTC

I often have the same issue as well. pkcon often hangs at the "Running" stage. I can fix it by running sudo apt full-upgrade.

Comment 5 amitabh.piyush 2021-12-19 00:19:53 UTC

pkcon is part of packagekit, it's bugs are tracked here: https://github.com/PackageKit/PackageKit/issues

Comment 6 Rishabh gupta 2023-11-21 10:44:35 UTC

Faced this same issue.  The solution was to run pkcon update with admin privileges(sudo)

I did not note the software versions before the update but after the update the versions are :

Thank you for your bug report! 
However this bug report was created/provided previous to 01/01/2023 and also has not received any updates since  before 01/01/2025. 
Unfortunately KDE neon no longer provides updates for anything older than noble 24.04 based edition's.
Please upgrade to KDE neon noble and if you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report.
Thanks for understanding!
