However, 18.04 is the latest LTS, so > it=E2=80=99s possibly worth doing eventually (but not right now). Hi guys, Just a ping to see if you have progressed on this. I've left the AArch* builders there, and now they're *really* behind (more than 1000 builds in the queue), and at least one of the buildslaves is offline. I will temporarily remove the builders now, but it would be really nice to keep having AArch* builders in our BuildBot.
