More user friendly message if repository is on read-only storage #202
Description
First of all, thanks for this awesome backup software! I am amazed how quick and efficient it is :-)
But it gives rather poor user feedback if the repository is on (remote) read-only storage:
$ sudo attic create "[email protected]:/media/3tb/backups/backup.attic::$(hostname)-$(date +%Y%m%dT%H%M%S)" /
Traceback (most recent call last):
