SUMMARY

When choosing "Sleep/Suspend" on the KDE menu, system doesn't go to Hibernate after a while although it is configured as suspend-then-hibernate.

If I don't select manually sleep/suspend in the KDE menu and let KDE manage it by itself, then it finally enters hibernation.

Configuration of powerdevil is:

$ cat .config/powerdevilrc
[AC][SuspendAndShutdown]
AutoSuspendIdleTimeoutSec=300
SleepMode=3


In system settings (I'm unsure about the proper english wording)
When inactive, sleep after 5min
When entering sleep: "suspend then hibernate"

STEPS TO REPRODUCE
1.  go to KDE Menu
2. select "sleep" or "suspend" (I don't know the proper english translation of it)

OBSERVED RESULT

System will enter suspend state, but never hibernate although configured as such

EXPECTED RESULT

Systems should enter suspend and then hibernate.

Thank you for the bug report!

Debian advises users to not submit bugs upstream (https://www.debian.org/Bugs/Reporting), and Plasma 6.3.x is no longer eligible for support or maintenance from KDE. It's possible that the issue exists only in Debian at this point.

Could you report the bug to Debian using the report bug utility (https://packages.debian.org/stable/utils/reportbug)? If necessary, the maintainer of the package will forward the bug upstream.

Thanks for understanding!

Being the reporter of the duplicate report, I took the liberty to report this downstream, as suggested by TraceyC:
