It does work for AppImages, but it is weird in that they don't have an install location, so that has to be adjusted for where they are placed on the system, or we have to set a security xattr on the executable at the time it is chmoded to +x
Admittedly orcaslicer doesn't use unprivileged user namespaces, but for it works for an example of how to put one of these on it. abi <abi/4.0>, include <tunables/global> profile orcaslicer /home/jj/Desktop/OrcaSlicer_Linux_V1.8.1.AppImage flags=(unconfined) { userns, # Site-specific additions and overrides. See local/README for details. include if exists <local/orcaslicer> } or we could make that looser by doing something like abi <abi/4.0>, include <tunables/global> profile orcaslicer @{bin}/OrcaSlicer_Linux_V1.8.1.AppImage flags=(unconfined) { userns, # Site-specific additions and overrides. See local/README for details. include if exists <local/orcaslicer> } or by setting the security.apparmor label on the binary sudo setfattr -h -n security.apparmor -v orcaslicer /PATH/TO/APPIMAGE and doing abi <abi/4.0>, include <tunables/global> profile orcaslicer xattrs=(security.apparmor=orcaslicer) flags=(unconfined) { userns, # Site-specific additions and overrides. See local/README for details. include if exists <local/orcaslicer> } -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apparmor in Ubuntu. https://bugs.launchpad.net/bugs/2046844 Title: AppArmor user namespace creation restrictions cause many applications to crash with SIGTRAP Status in apparmor package in Ubuntu: Confirmed Status in digikam package in Ubuntu: Confirmed Status in epiphany-browser package in Ubuntu: Confirmed Status in falkon package in Ubuntu: Confirmed Status in qutebrowser package in Ubuntu: Confirmed Bug description: Hi, I run Ubuntu development branch 24.04 and I have a problem with Epiphany browser 45.1-1 (Gnome Web): program doesn't launch, and I get this error $ epiphany bwrap: Creating new namespace failed: Permission denied ** (epiphany:12085): ERROR **: 14:44:35.023: Failed to fully launch dbus-proxy: Le processus fils s’est terminé avec le code 1 Trappe pour point d'arrêt et de trace (core dumped) $ epiphany bwrap: Creating new namespace failed: Permission denied ** (epiphany:30878): ERROR **: 22:22:26.926: Failed to fully launch dbus-proxy: Le processus fils s’est terminé avec le code 1 Trappe pour point d'arrêt et de trace (core dumped) Thanks for your help!
