I am using Debian Buster with maybe a couple of backports. I didn’t test bullseye, yet, but all these including Ubuntu should be fine.

The segmentation faults can happen and you can just restart the build and it should eventually go through.

For the nightly builds with are using native systems on AWS with their Graviton 2 processors. AFAIK there is no “budget” alternative to that.
