Hi Paul and Aniol, I encountered the same issue while working on autopkgtests for the vpnc package. Error message on salsa.d.o [1] is vpnc-connect: can't open /dev/net/tun, check that it is either device char 10 200 or (with DevFS) a symlink to ../misc/net/tun (not misc/net/tun): Operation not permitted The same error showed up running tests with my local debci/lxc installation. After some research on the net I could fix the issue locally by adding lxc.cgroup2.devices.allow = c 10:200 rw to the lxc container's config file /var/lib/lxc/autopkgtest-unstable- amd64/config. Now I wonder how to address the issue properly: - Raise a bug against lxc-templates? - Raise a bug against debci? - Bring up the topic to the Salsa CI Team? Let me know how to proceed.
