Hi,

udisks2's autopkgtest fails when tried together with util-linux 2.40. An
example can be seen here:

I do not understand what this error means, or what the underlying problem is.
Please investigate.

It appears that this is a regression introduced in util-linux 2.40-7.
The udisks2 test suite passes with 2.40-6.

So I assume it's one of the upstream changes from
