font-manager app crashes due to bwrap (apparmor)

[Attila Fülöp]

Hi,

When I select from the "Manage" menu the "Google fonts" the application crashes. It saves its state before crash, so next time the application does not even start (because it is in the "Google fonts" view).

If started from terminal, the following error message is printed:
-------------
bwrap: setting up uid map: Permission denied

** (font-manager:15240): ERROR **: 13:23:43.007: Failed to fully launch dbus-proxy: Child process exited with code 1
Trace/breakpoint trap (core dumped)

== 0 ==> lsb_release -rd
Description: Ubuntu 24.10
Release: 24.10

== 0 ==> apt-cache policy font-manager
font-manager:
  Installed: 0.9.0-3
  Candidate: 0.9.0-3
  Version table:
 *** 0.9.0-3 500
        500 http://archive.ubuntu.com/ubuntu/ oracular/universe amd64 Packages
        100 /var/lib/dpkg/status

As a quick workaround I created an apparmor profile with "userns", enabled it and started the application successfully.

I did not try the bwrap profile from apparmor-profiles_4.1.0~beta1-0ubuntu3_all.deb package.

Thanks,
Attila
