Can't create vivid lxc on trusty

[Jason Hobbs]

When I create a vivid lxc in trusty like this:

lxc-create -t ubuntu -n vivid-lxc -- -r vivid

I get this error at the end:

A partial workaround is to use the download template:

sudo lxc-create --name vivid -t download -- --dist ubuntu --release vivid --arch amd64

This yields a bootable container but it's still a bit weird: mine didn't get an IP address, one needs to lxc-attach to it and post-configure some items before it's usable via ssh as containers for other releases.

The ifup/ifdown scripts don't work because they're looking for files in /var/run which no longer exist; similarly, trying to dhclient eth0 fails with a problem setting up name resolution somewhere in /var/run: /etc/resolv.conf -> ../run/resolvconf/resolv.conf

So it's a bit flaky even with the download template.

This happens also trying to create a wily lxc

[Riccardo Padovani (rpadovani)]

So, it seems the default ubuntu template is broken.

A possible workaround is to download the template provided in the lxc's repo on GitHub[0] and replace to /usr/share/lxc/templates/lxc-ubuntu

Still, you have to configure network on your own

Better, add the stable lxc ppa and it fixes the issue.

sudo apt-add-repository ppa:ubuntu-lxc/lxc-stable
sudo apt-get update
sudo apt-get dist-upgrade

I can confirm the comment of Riccardo, Trusty host and Wily template doesn't seem to work:

Package lxcguest is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'lxcguest' has no installation candidate

We're now relying on lxc-download which doesn't have such problems.
A backported version of lxc in trusty will work fine, though trusty is eol now.
