Cannot access Debian 10 server after "apt update && apt upgrade" until physical reboot
by kevindd992002 from LinuxQuestions.org on (#5KAAE)
So I did the usual "apt update && apt upgrade" on two of my Debian 10 boxes and did a reboot. The upgrade process went just fine. I had no issues with one of the boxes as it came up pretty quick after reboot and I can access it through SSH as usual.
For the other box though, I was waiting for it to come back up by pinging it continuously and it never did until I needed to go to the actual server itself and powered it off using the power button (without holding it, just one press, so I assume this is not a force shutdown) and then it came back up as normal and I can access it through SSH again. Which log file should I be checking to see what happened why I was not able to access the server after that first reboot after the upgrade?
