Melodic currently has 3 regressions and 167 packages ready to sync.
The regressions are caused by an out-of-memory error when building a particularly large package on arm64; I’ve re-kicked it with the hope that we can get a build through for it.
I’m going to start holding Melodic packages as of today, April 23, and plan to do a sync early next week.
Please reply here if there are any other outstanding issues I should know about before performing a sync.
