Hi Lina

Try running aptitude update - to pull the updated list of packages - then
aptitude full-upgrade - you shouldn't see those sorts of inconsistencies.

Bullseye - Debian 11 - OK.

Temperature issue - only thinking that if it was something that only
happens after a long time, it might be because a componetn inside your
screen warms up / misbehaves.

Does anything else happen just before it all locks up?

All the very best, as ever,
