Here's the offending upgrade log. Although Mesa 13 was also introduced today, that does not seem to be the problem, since mir-demos still work fine.

[Albert Astals Cid (aacid)]

This is because everything in https://bileto.ubuntu.com/#/ticket/2160 landed except qtmir.

IMO Silos should be atomic, but they are not it seems, so that is what caused the breakage.

According to http://people.canonical.com/~ubuntu-archive/proposed-migration/update_excuses.html#qtmir qtmir depends on libmiral1 that doesn't even seem to exist?

$ apt-cache search libmiral1
$

[Daniel van Vugt (vanvugt)]

That would be bug 1651384 :P

[Michał Sawicz (saviq)]

That's because miral 1.0 was released in the mean time, with SONAME 2, so it's libmiral2 now.

Apart from that, old qtmir is used (instead of the fake one in unity8-fake-env that gets installed).

Third issue is that miral needs to get MIR'd (bug #1651384).

[Daniel van Vugt (vanvugt)]

Minor correction: The process starts and logs stuff. So that's not really failing to start. Depending on your view of "started" :)

[Daniel van Vugt (vanvugt)]

qtmir (0.5.1+17.04.20161216-0ubuntu2) zesty; urgency=medium

  * No-change rebuild against latest miral.
