It is a known issue with snaps in general and with chromium in particular that refreshing a snap while it's running may cause data loss/corruption, in this specific case the application profile. See bug #1616650, and I suggest enabling the refresh app awareness experimental feature (https://forum.snapcraft.io/t/wip-refresh-app-awareness/10736), to prevent refreshes from happening while the app is running.
About the apparmor denials, I haven't seen this myself. Is the amount of denials back to normal after closing the app and reopening it? ** Changed in: chromium-browser (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1859609 Title: [snap] lots of apparmor denials after snap update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1859609/+subscriptions -- ubuntu-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
