> bwrap might just be the tip of the iceberg... Yes this is not only bwrap. The other component I found to be affected is ubuntu-insights-collect.service, which does not invoke bwrap and instead just relies on systemd's PrivateUsers=true
> Running 'sysctl -w kernel.apparmor_restrict_unprivileged_userns=0' early in the livecd boot makes the most sense to me, but I could see us easily creating a race condition against systemd-sysctl.service Well we could put it in a systemd service with WantedBy=sysinit.target and After=systemd-sysctl.service (which is how apparmor.service normally starts) -- 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/2122675 Title: Cannot unshare userns in livecd Status in apparmor package in Ubuntu: Confirmed Bug description: Multiple components of Ubuntu Desktop daily-live are failing when trying to create a sandboxed user namespace: apparmor="DENIED" operation="userns_create" class="namespace" info="Userns create restricted - failed to find unprivileged_userns profile" error=-13 profile="unconfined" pid=9281 comm="bwrap" requested="userns_create" denied="userns_create" target="unprivileged_userns" execpath="/usr/bin/bwrap" This is seen affecting the loading of the wallpaper image (sandboxed through glycin -> bwrap) and the ubuntu-insights-collect.service (sandboxed through PrivateUsers=true in the unit file) Minimal reproducer: $ python3 >>> import os >>> os.unshare(os.CLONE_NEWUSER) Traceback (most recent call last): File "<python-input-1>", line 1, in <module> os.unshare(os.CLONE_NEWUSER) ~~~~~~~~~~^^^^^^^^^^^^^^^^^^ PermissionError: [Errno 13] Permission denied To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2122675/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
