Package: libpam-cgfs
Version: 2.0.7-0ubuntu4
Severity: important
Dear Maintainer,
I couldn't start my unpriviledged containers anymore, seems like the
libpam-cgfs is the culprit, according to the discussion I had here :
https://discuss.linuxcontainers.org/t/failed-creating-cgroups/272/6l
Installing the ubuntu package solved my issue
Using the debian package 2.0.7-1 leads to this type of error while trying to
start an unpriviledged container
