LXC package for trusty no longer has configuration files

[Craig Maloney]

Did an upgrade this morning to the latest LXC package (via the updates channel).

LXC Package 2.0.1-0ubuntu1~ubuntu14.04.1 no longer has the configuration files under /usr/share/lxc/config. This causes lxc-ls to complain about missing template files.

lxc-ls: parse.c: lxc_file_for_each_line: 57 Failed to parse config: lxc.include = /usr/share/lxc/config/ubuntu.common.conf

Do I need to change the container's configuration to point to a new location?

[Craig Maloney (craig-decafbad)]

Copied over the config from lxc-2.0.1/config/templates to /usr/share/lxc/config and it appears to be working. So the files seem to be missing.

[Stéphane Graber (stgraber)]

Could it be that you somehow don't have the lxc-templates package installed?

[Craig Maloney (craig-decafbad)]

I do, but the templates don't seem to have the .conf files:

My guess is that you lxc-templates is from LXC 1.1 while the rest is LXC 2.0.

Partial upgrades aren't supported.

[Serge Hallyn (serge-hallyn)]

Can you show the output of

dpkg -l | grep lxc

?

[Craig Maloney (craig-decafbad)]

craig@lister:~$ dpkg -l | grep lxc

ii liblxc1 2.0.1-0ubuntu1~ubuntu14.04.1 amd64 Linux Containers userspace tools (library)

ii python3-lxc 2.0.1-0ubuntu1~ubuntu14.04.1 amd64 Linux Containers userspace tools (Python 3.x bindings)

So it's an old package, but I'm not offered the latest package when I try apt-get update && apt-get dist-upgrade.

What's the best way to fix this?

The version you have of the other lxc templates is from backports, so perhaps you need to manually request that?

apt install -t trusty-backports lxc-templates

or something. I never use backports, stgraber can probably help you, if the above does not work.

[Craig Maloney (craig-decafbad)]

Thank you, that did the trick.

Not sure how it got into that state though. Some guidance on what I did wrong would helpful. :)

Thanks again!

[Serge Hallyn (serge-hallyn)]

Hi,

I suspect this points to a problem in the packaging - the lxc1 package
should probably have a >= versioned dependency on lxc-templates. That
way, apt install -t backports lxc1 would have automatically upgraded
lxc-templates for you.

So I do think this is a real bug in trusty-backports.

thanks for reporting this!
