Comment # 1 on bug 1093039 from Ignaz Forster

According to
https://openqa.opensuse.org/tests/674696#step/transactional_update/133 a
rollback to snapshot 4 is done. However this is not the snapshot you want -
Kubic contains a newer version of transactional-update compared to CAASP which
is generating two snapshots for each run (due backing up the /etc state - see
e.g. https://openqa.opensuse.org/tests/674696#step/one_line_checks/3 where
snapshot #4 is already taken).

The fix should be trivial: What you want to do here is roll back to snapshot #6
(the first one to contain the package if I've counted correctly) instead.
