SamLukeYes [1] filed a deletion request for deepin-udis86 [2]:
This package was deleted because it didn't follow package guidelines.
If the 32-bit binary package from deepin is really needed, it should
be named as lib32-udis86-deepin-bin, and avoid the conflict to the
64-bit package udis86. deepin-udis86 should only exist as a string in
provides for backward compatibility, since there are packages
depending on this name, which is not correct.
