[Bug 1565362] Re: Try to upgrade to xenial with a sudo do-release-upgrade -d

[Brian Murray]

I think the upgrade fails to be calculated due to this:

Investigating (5) libgtk-3-0 [ amd64 ] < 3.10.8-0ubuntu1.6 -> 3.18.9-1ubuntu3 > ( libs )
Broken libgtk-3-0:amd64 Dépend on libwayland-egl1-mesa [ amd64 ] < none -> 11.1.2-1ubuntu2 > ( libs ) (>= 10.0.2)
  Considering libwayland-egl1-mesa:amd64 -1 as a solution to libgtk-3-0:amd64 214
  MarkKeep libgtk-3-0 [ amd64 ] < 3.10.8-0ubuntu1.6 -> 3.18.9-1ubuntu3 > ( libs ) FU=0 
  Holding Back libgtk-3-0:amd64 rather than change libwayland-egl1-mesa:amd64
Broken libgtk-3-0:amd64 Dépend on libwayland-egl1 [ amd64 ] < none > ( none )
  Considering libwayland-egl1-mesa-lts-utopic:amd64 8 as a solution to libgtk-3-0:amd64 214
  Added libwayland-egl1-mesa-lts-utopic:amd64 to the remove list 
  Fixing libgtk-3-0:amd64 via keep of libwayland-egl1-mesa-lts-utopic:amd64
  MarkKeep libwayland-egl1-mesa-lts-utopic [ amd64 ] < 10.3.2-0ubuntu1~trusty2 > ( libs ) FU=0 

Maybe if you switch to mesa-lts-vivid or mesa-lts-wily things will work
out better.
