Started misbehaving on April 17th 2024. $ snap info chromium ... snap-id: XKEcBqPM06H1Z7zGOdG5fbICuf8NWK5R tracking: latest/stable refresh-date: today at 08:58 CEST channels: latest/stable: 123.0.6312.122 2024-04-15 (2821) 168MB - ... When running chromium, it complains about not being able to open my home dir: cannot update snap namespace: cannot expand mount entry (none $HOME/.local/share none x-snapd.kind=ensure-dir,x-snapd.must-exist-dir=$HOME 0 0): cannot use invalid home directory "/home/tannerli": permission denied snap-update-ns failed with code 1 AppArmor log shows that access to ecryptfs private folder was denied: Apr 18 13:13:21 hostname kernel: audit: type=1400 audit(1713438801.579:437): apparmor="DENIED" operation="open" class="file" profile="snap-update-ns.chromium" name="/home/.ecryptfs/tannerli/.Private/" pid=32412 comm="5" requested_mask="r" denied_mask="r" fsuid=1000 ouid=1000 I found out, that, under /var/lib/snapd/apparmor/profiles, while snap.chromium.chromium has the line owner @{HOMEDIRS}/.ecryptfs/*/.Private/ r, the file snap-update-ns.chromium does _not_ have the line. Adding it and reloading the profile allows chromium to start again. I'm nowhere near experienced enough to tell whether this line should be added by default or something else went wrong on my machine.
