The issue is that snap-confine has a debian/snap-confine.maintscript that deal with upgrades in the debian version of the package. However we do not have a version of snap-confine in xenial yet.
Fwiw, this is a bug in dpkg-maintscript-helper because it should deal with the case that there is no previous version without showing a huge error message: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=582819 We have two options here, backport the fix for dpkg-maintscript-helper or trying to workaround this issue in snap-confine. ** Bug watch added: Debian Bug tracker #582819 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=582819 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1605052 Title: snap-confine: dpkg --compare-versions error outputs during installation from snapd/ubuntu-core-launcher upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/snap-confine/+bug/1605052/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
