Public bug reported:
Snapd currently checks for
/sys/kernel/security/apparmor/features/network. If that directory does
not exist, we get
$ sudo env SNAPD_DEBUG=1 systemctl restart snapd
$ sudo journalctl -u snapd.service -n 20 | cat
backends.go:70: AppArmor status: apparmor is enabled but some kernel features
are missing: network
In the upstream kernel only
/sys/kernel/security/apparmor/features/network_v8 and
/sys/kernel/security/apparmor/features/network_v9 exist.
Installing snaps with --jailmode fails when using upstream or vendor
kernels. It would be helpful to rely on upstream Apparmor network
features instead.
Best regards
Heinrich
