So yes, the weekly LineageOS builds have been a bit sporadic lately.
Both deb and flo 14 builds started claiming that the jack server had disappeared. I temporarily removed them, which made other builds complete, but the build times would range wildly between one hour to six-plus hours per.
I’ve tweaked the build infrastructure (yet again!) to spread out the load a bit. Builds are now going to happen a few batches per day, Monday through Wednesday. I’ll keep an eye on things and see how it goes.
