Comment 2 for bug 1830823

That commit has been in xenial since October and is not the proximate cause of livecd-rootfs being uninstallable on powerpc. The timeline (breaking on the 23rd) DOES align with ubuntu-image 1.7 being published to xenial-updates. The diff of that ubuntu-image shows that the versioned dependency on snapd is bumped to be >= 2.38; which is not satisfiable on powerpc because snapd is not buildable on powerpc with gccgo (vs golang).

I believe this will be fixed in the next upload of snapd, which will make snapd an empty package on powerpc instead of failing to build.
