Public bug reported:
After upgrade from xenial to bionic (beta) I no longer could start
unpriveleged containers, they failed with following message:
lxc-start: test: start.c: lxc_spawn: 1555 Failed initializing cgroup support
lxc-start: test: start.c: __lxc_start: 1868 Failed to
spawn container "test"
The container failed to start.
Additional information can be obtained by setting the --logfile and
--logpriority options.
Moreover, I could see this in auth log:
Mar 23 18:21:46 host sudo: PAM unable to dlopen(pam_cgfs.so):
/lib/security/pam_cgfs.so: cannot open shared object file: No such file or
directory
Mar 23 18:21:46 host sudo: PAM adding faulty module: pam_cgfs.so
I have installed libpam-cgfs, but it provides only /lib/x86_64-linux-
gnu/security/pam_cgfs.so
Moreover, if I create a symlink from /lib/security/pam_cgfs.so to
/lib/x86_64-linux-gnu/security/pam_cgfs.so it fails with follwing
message:
