FFE: 18.2.x for cosmic

+1 from desktop team, we would like to see that update in cosmic

fwiw it's available on ppa:canonical-x/x-staging and I've been running a RC for some weeks now on my laptop without issues.

18.2.1 was released today and I'll push it there soon.

I would like to wait with this until the new 18.2.1 version builds. Could you perform some upgrade testing on it and leave a comment about how it went? I'll pick this up tomorrow and we'll decide then.

The LLVM 7 part seems like a separate thing though? Since it still doesn't seem to be available, I guess it would require another FFe/NEW, I suppose? Seems a bit bigger, especially so close to release.

LLVM 7 is the default in cosmic :)

and mesa 18.2.1 is built now, installs fine from the ppa

Duh, I blame the source naming change (previously it was llvm-toolchain-6.0, now it's just -7 instead of -7.0, ugh). Anyway, nevermind me!

I think I'm fine with the changes introduced and the testing so far. It's always better to have a more up-to-date stack. I also confirmed with Adam that we're ok with it. So: approving the FFe.

This bug was fixed in the package mesa - 18.2.1-1ubuntu1
