Before choosing to reinstall, I think it’s not too late to read the following URL.
I believe the writer has no ill intentions. However, depending on the case, you may feel that it is not a joke, but I think it will be very helpful.
Extra note:
Maybe it’s pamac gui?
It crashes occasionally.
But I don’t know if the Manjaro Team is doing any validation.
One of the problems for users is that the upgrade is often proceeding behind the scenes even after the crash. It’s too late now, but in this case, wait until the CPU is idle.
Or start top or something and check if the upgrade is proceeding.
I can’t start a new update due a locked database.
The same goes for this, wait.
Do not reboot. Wait 5 minutes and it should be fine.
