[Lxc-users] LXC-Create fails after upgrade to Ubuntu 12.10 from 12.04

[bmullan]

last week I upgraded from Ubuntu 12.04 to 12.10 and since then LXC no longer
works correctly.

creating a simple LXC container:

    sudo lxc-create -t ubuntu -n cont1

appears to be working ok until it gets to the following error near the end:

Container upgrade failed.  The container cache may be out of date,
in which case flushing the case (see -F in the hep output) may help.

I've been doing google searches and have read the mail list and although there
appears to be people having various problems with LXC-START ... which I have
seen also.   I am at a loss as to how to troubleshoot this further.

Thanks for any tips/hints.
