Comment 8 for bug 1818285

I'm reassigning to partman-base.

If I replace /bin/parted_server from Ubiquity 19.04.6 by the version of the binary package of 19.04.5 it fixes the issue. According to the d-i manifest and the source diff only user-setup has been updated in .6 but the following files are different:

ubiquity_19.04.5_amd64/bin/blockdev-wipe
