[Bug 2046844] Re: AppArmor user namespace creation restrictions cause many applications to crash with SIGTRAP

[Tobiyo Kuujikai]

this did not solve my issue with testing Nextcloud-Talk:
https://github.com/nextcloud/talk-desktop/issues/588

i attempted to create an apparmor profile for it but it did not work:
# This profile allows everything and only exists to give the
# application a name instead of having the label "unconfined"
 
abi <abi/4.0>,
include <tunables/global>
 
profile Nextcloud-Talk /** xattrs=(security.apparmor=Nextcloud-Talk) flags=(unconfined) {
  userns,
 
  # Site-specific additions and overrides. See local/README for details.
  include if exists <local/Nextcloud-Talk>
}
