We have just merged a fix that hopefully will work around the most major problem right now: Build timeout (!437) · Merge requests · F-Droid / fdroidserver · GitLab
That will need a few more days of testing before it’ll get deployed. After that the buildserver can hopefully start working through that backlog here: https://f-droid.org/wiki/page/Category:Apps_with_failing_builds
(It’s called failing builds, but most of these are just unbuilt-apps)
It’'ll still take a week or so to built ~150 apps probably.
