Since the Friday daily build (Nov. 17) the core snap is blocked by a failing auto-review in the store, seemingly snap-confine changed which causes the following review error:
found errors in file output: unusual mode 'rwsr-sr-x' for entry './usr/lib/snapd/snap-confine' security-snap-v2_squashfs_files
i guess either the review tools need updating or snap-confine needs reverting …
This happens on all arches across the board …
