Public bug reported: Since impish, dpkg defaults to the zstd compression format for compressing the members in a deb package archive [1,2].
However Debian zstd support efforts are still in progress [3]. Therefore, running autopkgtest from an Ubuntu (>= 21.10) host on a Debian target fails, since autopkgtest uses dpkg-deb to generate the autopkgtest-satdep.deb package. For instance, running the following commands for a given package $ autopkgtest-build-lxd images:debian/sid $ autopkgtest ./. -- lxd autopkgtest/debian/sid/amd64 results in the following error: autopkgtest [18:32:17]: build needed for binaries autopkgtest [18:32:24]: ERROR: "dpkg --unpack /tmp/autopkgtest.4vFMyL/1-autopkgtest-satdep.deb" failed with stderr "dpkg-deb: error: archive '/tmp/autopkgtest.4vFMyL/1-autopkgtest-satdep.deb' uses unknown compression for member 'control.tar.zst', giving up dpkg: error processing archive /tmp/autopkgtest.4vFMyL/1-autopkgtest-satdep.deb (--unpack): dpkg-deb --control subprocess returned error exit status 2 Errors were encountered while processing: /tmp/autopkgtest.4vFMyL/1-autopkgtest-satdep.deb [1] https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/1923845 [2] https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/1923845/comments/34 [3] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=892664 ** Affects: autopkgtest (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1947810 Title: autopkgtest-satdep.deb unpack fails on Debian images To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/autopkgtest/+bug/1947810/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
