Looking at the logs, it may be the case that it's due to path length restrictions on UNIX domain socket filenames. I'm checking if that's the case now. If so, I suggest that any sockets are created in /tmp or TMPDIR rather than the build tree to avoid such issues. TMPDIR can always be set to /tmp. Since sbuild/buildd build in /build/$user-$package_$version-$arch-XXXXX/$package_$version, that's a large chunk of the (114? char length) socket restriction. We've had this issue before. Ultimately: - we can mitigate the restriction by making the path shorter, but we can't make any guarantees even than since package names and version numbers don't have any fixed limit. You still have to factor in the relative path length under the build tree as well. - using a guaranteed short path under /tmp is the only way to ensure success. My home dir at work is over five levels deep from the root, so upstream really should deal with the limitation since users don't always have the choice of shortening the path. Regards, Roger -- .''`.
