** Description changed: - Hi, I reported a socat regression that only appears in version 1.7.3.3: + [Impact] + The socat version in Focal, 1.7.3.3, has a regression that breaks the "remote terminal" functionality of the "epoptes" package. + + I reported it to Debian, and the Debian maintainer packaged the new socat 1.7.3.4 which solves the issue: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=958452 - The Debian maintainer just packaged the new version 1.7.3.4 which solves - the issue. - - Is it possible to get that in Focal? It could be considered a microrelease: + This new upstream version is a bug fixing release which I believe can be considered a microrelease: https://wiki.ubuntu.com/StableReleaseUpdates#New_upstream_microreleases + Please sync it to focal-proposed. + [Test case] Here are the regression details, in order to be able to reproduce it: - Epoptes is a computer lab management tool, I'm upstream and - Debian maintainer for it. It uses socat to forward a "student" terminal - to the "teacher".

It's a bug fixing upstream release. + I have compiled 1.7.3.4 from source and I've been using it for about a month with no visible issues. I also installed the .deb from sid to my focal box today and it appears to work fine. + Note though that https://tracker.debian.org/pkg/socat shows a unit test failure on arm64 (networkd-test.py), I don't know if that was the case with previous versions or not.
