upgrade adoption looks good, we may well be able to kill xenial in the week of Oct 8.
‼ make sure we don't need to build anything anymore before we actually go ahead with this ‼
(Oct 8 update: upgrade rate coming to a crawl. EOL notification needs pushing out and then we can move ahead with killing)
- snap builds rely on 16.04. needs testing+porting+moving to 18.04 (at least requires frameworks rejiggering as the original version isn't designed for an ABI split)
- possibly should green up what we have or at least review why it's red?
