The following packages have unmet dependencies:
wireshark : Depends: wireshark-qt (= 3.2.3-1) but it is not going to be installed

Chasing down the dependency chain this is because libegl-mesa0 depends on libwayland-client0 (>= 1.20.0) but there only is 1.18.0-1ubuntu0.1 available.
I guess I can just look for a PPA with more recent builds of that, but the current situation is... not ideal? I get that this is for testing mostly, but if you have an existing setup with this PPA and do apt full-upgrade you're left without a working graphical session as far as I can tell.
So, not sure whether this is "works as expected" or an accident; I thought I'm gonna open an issue just in case.
