Openhabian corruption on RPI3b

Hello,
I need help for several consecutive corruption of my system.

I use openhabian. Around 16:00 today the system (fresh install 1 w ago) goes offline.
When I arrived at home these is the screen from the RPI

Not able to do nothing cause error on every command
sudo apt-get update or upgrade do not work.
I’m not able to understand how to do at all at these point.

I try sudo reboot but same problem still there.

Can some linux expert try to help me =(?

  • has there been a power failure ?
  • are you able to login as openhabian ?
  • after logging in to openhabian are you able to do “sudo bash” ?
  • in case sudo does not work: what is the output of: “ls -l /usr/bin/sudo”

I try to make a fresh install + restore backup on a new SD card.
Because not happens once but pev times I did not take a photo of the RPI screen output.

In case the problem occure soon also with these new SD I can exclude a piece of the puzle and I will try your lines command that I didn’t know before.

Make it sense for you these strategy ?

Tank you very much
