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 :
