@arraybolt3: Answer to your question. bwrap requires capabilities within the user namespace. unshare is a little more forgiving in that what it requires depends on the options passed but most of the options also require capabilities within the user namespace.
The potential solution I mention is comment #91 is to define a profile for bwrap that allows it capabilities within the namespace but does not allow its children capabilities within the namespace, so that bwrap and unshare can not just launch an application to by-pass the restriction. This seems to work well for unshare but there are cases where bwrap is failing in unexpected ways (which is still being debugged). At this late stage the plan is to try to get a fix for bwrap in but if necessary to file an SRU if necessary for the bwrap fix. So yes this is being worked on and even if the fix isn't present on day one we do plan to get it fixed. -- You received this bug notification because you are a member of Ubuntu Studio Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/2046844 Title: AppArmor user namespace creation restrictions cause many applications to crash with SIGTRAP Status in AppArmor: New Status in akonadiconsole package in Ubuntu: Fix Released Status in akregator package in Ubuntu: Fix Released Status in angelfish package in Ubuntu: Fix Released Status in apparmor package in Ubuntu: Fix Released Status in bubblewrap package in Ubuntu: Confirmed Status in cantor package in Ubuntu: Fix Released Status in devhelp package in Ubuntu: Fix Released Status in digikam package in Ubuntu: Fix Released Status in epiphany-browser package in Ubuntu: Fix Released Status in evolution package in Ubuntu: Fix Released Status in falkon package in Ubuntu: Fix Released Status in firefox package in Ubuntu: Confirmed Status in freecad package in Ubuntu: Invalid Status in geary package in Ubuntu: Fix Released Status in ghostwriter package in Ubuntu: Fix Released Status in gnome-packagekit package in Ubuntu: Invalid Status in goldendict-webengine package in Ubuntu: Fix Released Status in kalgebra package in Ubuntu: Fix Released Status in kchmviewer package in Ubuntu: Fix Released Status in kdeplasma-addons package in Ubuntu: Fix Released Status in kgeotag package in Ubuntu: Fix Released Status in kiwix package in Ubuntu: Incomplete Status in kmail package in Ubuntu: Fix Released Status in konqueror package in Ubuntu: Fix Released Status in kontact package in Ubuntu: Fix Released Status in loupe package in Ubuntu: Fix Released Status in marble package in Ubuntu: Fix Released Status in notepadqq package in Ubuntu: Fix Released Status in opam package in Ubuntu: Fix Released Status in pageedit package in Ubuntu: Fix Released Status in plasma-desktop package in Ubuntu: Fix Released Status in plasma-welcome package in Ubuntu: Fix Released Status in privacybrowser package in Ubuntu: Invalid Status in qmapshack package in Ubuntu: Fix Released Status in qutebrowser package in Ubuntu: Fix Released Status in rssguard package in Ubuntu: Fix Released Status in steam package in Ubuntu: Fix Released Status in supercollider package in Ubuntu: Fix Released Status in tellico package in Ubuntu: Fix Released 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!
