Hello, after thinking a little bit more, a Provides might even be enough to satisfy the dependency.
To reproduce this issue: pbuilder-dist sid login apt-get install sane-utils add experimental repo: apt-get dist-upgrade -t experimental Reading package lists...

Need to get 57.3 MB/57.3 MB of archives. After this operation, 140 MB of additional disk space will be used. Do you want to continue? [Y/n] Looks like it is trying to remove libsane and sane-utils instead of upgrading the latter G.
