Description

The upgrade test fails in the teardown phase because a database directory cannot be deleted.
Happens for a varying number of version combinations, I've seen from one to five failed tests (out of 2496 tests) so far. See attached files for some examples.

The error is reproducible running the upgrade suite standalone.
