This error occurs when attempting to restore a configuration backup in Rockstor 3.8.16-16.
It is apparently fixable by editing line 235 of /opt/rockstor/src/rockstor/storageadmin/views/config_backup.py to be:
cbo = self._validate_input(backup_id, request)
?
Hi @kbogert,
thanks for this, there’s an open PR on Github covering this too

Any update on this?
I’ve just pulled a fresh 3.9.0 installation, put it on a new USB stick and am unable to import my previous 3.8.5 config.
It appears to still be an open PR?
I don’t really have the courage to connect my sata-power cables again and manually pull in the files with delta’s TBH…
Hi @FVerdi,
you’re right about open PR
