Hello,
Since this happened after power loss, and both Apache and Plinth services have failed at the same we are looking at possible disk corruption (this should have been impossible unless due to hardware issues). Could you please check:
- Did you run out of disk space
df -h. - Is your disk mounted read-only (due to filesystem errors). Output of
mount. - What happens when you try to strat Plinth on command line?
sudo -u plinth plinth. - What do the logs for apache and plinth show?
journalctl -u plinth,journalctl -u apache2? - Do you see any errors during boot or system logs
journalctl?
