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
