Hi, The autopkgtest regression is now fixed in the new version 0.9-1+dfsg-1 which passes according to debci [1]. BUT, if we look at the log file there are a lot of errors which are not detected (?) by debci [2]. By looking at the history of tests, it seems this behavior was already present in the oldest log (2019-12-14). So, probably there are not a regression, but anyway these errors should be fixed as well.
