Title:
bubbewrap cannot create namespace - Failed RTM_NEWADDR: Operation not
permitted
Status in apparmor package in Ubuntu:
Confirmed
Bug description:
Hi, I am the developer of Web Apps
(https://flathub.org/apps/net.codelogistics.webapps) which is a
Flatpak application which uses XDG Desktop Portal's Dynamic Launcher
portal to create desktop files. However, on Ubuntu 24.04, this fails
with this output in the terminal:
`GDBus.Error:org.freedesktop.portal.Error.InvalidArgument: Dynamic
launcher icon failed validation`
which is apparently due to Ubuntu deciding to use Apparmor to restrict
the creation of user namespaces in bubblewrap.
Unfortunately I don't use Ubuntu or have any idea about what apparmor or
bubblewrap are, but I have come to know from
https://gitlab.gnome.org/GNOME/epiphany/-/issues/2357 and
https://etbe.coker.com.au/2024/04/24/
ubuntu-24-04-bubblewrap/ that this issue is being caused by apparmor on
Ubuntu. Please refer to these links for complete details about this issue.
I am using Ubuntu 24.04 LTS, GNOME 46 on Wayland and apparmor version
4.0.0-beta3-0ubuntu3.
