As seb128 found, the issue is also affecting the debian package of snapd since when we call mksquashfs, we actually have code which specifically calls mksquashfs from the "system" snap which is either the snapd snap or the core snap, this is presumably to ensure that a consistent mksquashfs is used always and to avoid snaps from being packed with too old or new mksquashfs's.
So the net effect is that the fix for this that was landed into the snapd snap will also probably need to be added to the core snap for completeness, and also means that the only way to avoid snap pack from failing is to have a snapd snap with the fix which is only available on the edge channel currently. So long story short, if you are affected by this today, a short-term workaround is to use the edge channel of the snapd snap by running snap refresh snapd --edge We have already included the fix into the snapd snap that is built on edge and it will be included in the release branch for 2.52, meaning that the next bugfix release on 2.52 will have the fix, we do plan on doing a 2.52.1 release in short order after 2.52 is complete, but it may be a few weeks from now before that is on stable. ** Changed in: snapd Milestone: None => 2.52 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1943077 Title: snapd fails to autopkgtest on mksquashfs, which is looking for libgcc_s To manage notifications about this bug go to: https://bugs.launchpad.net/snapd/+bug/1943077/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
