Dependencies broken with most recent release

[srett]

I'm setting up a fresh Ubuntu 20.04 (focal) environment with deboostrap:

debootstrap --variant=minbase --arch=amd64 \
   --include="build-essential,dbus,binutils,lsb-release,wget,rsync,nano,software-properties-common" \
   "focal" "/tmp/testroot" ""http://ftp.fau.de/ubuntu"

Change sources.list to add updates/security/etc.:

deb http://ftp.fau.de/ubuntu focal main restricted universe
deb http://ftp.fau.de/ubuntu focal-updates main restricted universe
deb http://ftp.fau.de/ubuntu focal-security main restricted universe

Then I add the PPA:

add-apt-repository ppa:ernstp/mesarc

After that, e.g. apt install wireshark gives me:

Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 wireshark : Depends: wireshark-qt (= 3.2.3-1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

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.

Aah I think I know what that is...

Should be solved now.
