Status in apparmor package in Ubuntu: New Bug description: In Focal, abstractions/X has the following section in it: # the unix socket to use to connect to the display /tmp/.X11-unix/* rw, unix (connect, receive, send) type=stream peer=(addr="@/tmp/.X11-unix/X[0-9]*"), unix (connect, receive, send) type=stream peer=(addr="@/tmp/.ICE-unix/[0-9]*"), However, in Impish, this seems to have changed: # the unix socket to use to connect to the display /tmp/.X11-unix/* r, unix (connect, receive, send) type=stream peer=(addr="@/tmp/.X11-unix/X[0-9]*"), unix (connect, receive, send) type=stream peer=(addr="@/tmp/.ICE-unix/[0-9]*"), This in turn breaks torbrowser-launcher's Firefox from launching, even if we include the X abstractions, because the display sockets in /tmp/.X11-unix/* (X0 for Display :0 for example) are not read/write. This looks like a MAJOR regression by removing the permissions. Or has Impish apparmor not been updated for any Ubuntu specific changes?
