Filed to open apps.
I tried the solution from #2458, but it didn't help.

For me, the fix was to change a setting for my proxmox lxc container. My CasaOS is an LXC on proxmox, so it had something to do with app armor. This was after reinstalling CasaOS on the command line after a docker update borked it up.

I adedd these two lines to the LXC container#.conf file in /etc/pve/lxc/$CTID.conf
lxc.apparmor.profile: unconfined

lxc.mount.entry: /dev/null sys/module/apparmor/parameters/enabled none bind 0 0

After rebooting the casaos LXC container, casa os install apps are now starting to work.

If your not on Proxmox then sorry to lead you down this path. Took me awhile to find this on Big Bear Repository's discussion forum.
