Source: buildbot Version: 4.2.1-1 Severity: important Tags: patch upstream Dear Maintainer,
Hi, Since upgrade to Debian 13 Trixie, buildbot is not showing any logs in any of actions. I believe that this bug is reproducible on all Trixie systems even freshly installed ones. This bug was seen on FreedomBox build infrastructure. An error was repeatedly seen in twisted.log for the build master (traceback follows this bug report). The traceback shows that code tried to import buildbot.test module. This module is (correctly) not shipped in Debian. This error is caused by a regression in upstream[1] during cleanup (present in versions 3.9 upto 4.3). It was fixed[2] in version 4.3 of upstream. The fix is quite small if you wish to backport to Debian Trixie's version 4.2.
