[lxc-users] Download and install trusty-64 unprivileged container cannot start anymore, requires system reboot to work - used to work

Hello Fajar,

> A quick look says both ppa are using 2.0.1, so you should have identical result.

Yeah that's what I expected as well. I only need to switch the use of the ppa and it either works or not.

If I do e.g. lxc-start --version it for both (stable or lts) reports 2.0.1 indeed.

Turs out to be a good guess! :)

But there is a difference after all with the installations, dependency wise. Below the packages that are installed/suggested etc. for both (it says LTS / STABLE at the top of each):

**** LTS ****

As you can see, dependencies are different of what is installed and what is not for both. At least libpam-cgfs is not installed for stable (anymore?), which causes the issue I have. I can't install it separately either that fails. 

If both are supposed to be exactly the same atm, this should not be the case perhaps?

Thanks,
