This is the page you could always go to https://buildd.debian.org/status/package.php?p=singularity-container&suite=unstable to get the logs (click on Build-Attempted) I can provide you access to mipsel, and possible sparc (when I bring it back online, that poor elderly beast with failing fan), and soon powerpc. -- Yaroslav O.
