amcheck: critical (fatal): create debug directory "/var/log/amanda/server/": Permission denied
amcheck: create debug directory "/var/log/amanda/server/": Permission denied
[13:24:14] backup@ohab3:~$ amreport openhab-dir
amreport: critical (fatal): create debug directory "/var/log/amanda/server/": Permission denied
amreport: create debug directory "/var/log/amanda/server/": Permission denied
- no logs on frontail, no log files on files system:
openhabian@ohab3:~ $ ls /var/log/openhab
ls: cannot access '/var/log/openhab': No such file or directory
- later (when i looked aht the logs on the console) i also noticed problems with mosquitto :
