After a few years of working, my HA installed on a Raspbery Pi suddenly stopped working - no automations, no web-ui, no terminal, SCP, Samba… only ping reacted.
When attaching monitor an keyboard right to the RasPI I can see a string of error messages, everytime I try to launch HA (ha command, even ha help fails), the first one is:
unexpected return pc runtime.doinit
I am very unexperienced with Linux systems and the internal structure of HA, so any kind of help would be highly appreciated.
First of all, I’d like to backup my config, but none of the folders I see in the documentation like /backup do exist… I assume I am looking in the wrong place, or maybe some mount missing?
Secondly, I would love to get this running again (worst case, I’ll do a fresh install after backing up the config) - any idea what this error message could point to, or where I should look to root-cause the issue?
HA simply stopped working without any change being done for months. Probably I should test the SD card…?
Thanks in advance for any help!
