Recently I had issues with NetworkManager. When I try to restart or close
NetworkManager, the process hangs. First it sends a SIGTERM to the
NetworkManager process, and after a while it sends SIGKILL, yet nothing
happens. After the attempt to restart/close NetworkManager, the OS behaves
badly:
- journalctl doesn't work, doesn't output anything, SIGTERMing/SIGABRTing/
SIGKILLing it causes the kill command to hang (no matter how many times I try
it), it also hangs the terminal
- 'sudo dmesg' hangs (killing it with SIGKILL/SIGTERM/SIGABRT hangs the kill
command, can't close the terminal)
- the OS won't reboot/suspend/shutdown (it does only after holding the restart
button)
Suspending/rebooting normally/shutdowning normally the laptop hangs the OS
(because of NetworkManager).
What I've tried:
- reinstalling NetworkManager (uninstalling it using --purge, installing it clean)
- deleting ~/.config
- deleting ~/.cache
- installing a version from NetworkManager from Debian (version: 1.8.4.2),
reinstalling NetworkManager from Ubuntu back
