doronbehar [1] filed a deletion request for mpdris [2]: 1. Upstream is dead (`https://ayeon.org` is dead) 2. no one has tried to fix the bug reported in the last comment. 3. There is another package mpdris2 which is named weird as well but it provides the same functionality and it works so it should get the name-space `mpdris`.
