The following message is "normal" and does not indicate a problem:
[cbbLocalManagement] [ CBB ] [ 1 ] Error on remove old icon file, path: /opt/local/CloudBerry Backup/share/webAccess/img/MainIcon.ico error: Permission denied
It's this one that is problematic:
[supervisor ] service 'cbbLocalManagement' failed to be started: not ready after 5000 msec, giving up.
Did you see the error once and reverted to the previous version?
