@stibinator

I can't reproduce the original report and since no one else has reported it I'm closing this issue out.

@fedkad

None of the errors in your output relate to the application or this issue...

bwrap: setting up uid map: Permission denied

That suggests an issue with AppArmor. If you installed from the PPA open a new issue.

If you installed using some other method add a file to /etc/apparmor.d named font-manager with the following contents:

# 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 font-manager /usr/bin/font-manager flags=(unconfined) {
  userns,

  # Site-specific additions and overrides. See local/README for details.
  include if exists <local/font-manager>
}
