Comment 15 for bug 1715582

I tried to monitor via jouralctl -f

first attempts suggest that the application can't create a directory /var/cache/samba

I added write access to /var/cache for world.

Then I got this

Mounting the directory manually

The mount works though.

Same issue.

Tried sudo chown o+w /run

Mounting the share does not bring up any error messages any more.

Deja-dup still fails
and there are no files created in cache or run

Still: the old deja-dup from Ubuntu 17.04 works fine.
