Sorry for reopening this topic.
I’ve found another issue:
After running sudo apt update, I then run sudo reboot, but my laptop hangs and refuses to reboot, even though the screen already displays “Reached target reboot”.
This happens with both kernel 6.8.0-134 and 6.8.0-136.
If I don’t run sudo apt update, the laptop reboots normally.
However, if I shut it down instead, it shuts down normally, both after running sudo apt update and without running it.
It’s not a major problem, since I can simply shut down the laptop and turn it back on whenever I want to reboot. I’m just curious about what might be causing it.
