Why is lxc-docker being held back? I also notice that my web app, running on Docker, is quite slow. Any suggestions?

[lucas@production]/home/lucas$ sudo apt-get dist-upgrade

The following package was automatically installed and is no longer required:
  linux-image-3.16.0-28-generic
Use 'apt-get autoremove' to remove it.
The following packages have been kept back:
  lxc-docker
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

Note that I have already run sudo apt-get dist-upgrade, which does not resolve this issue. Thus, I don't think my questions is a duplicate of this questions

  • Whats the output of `dpkg --get-selections | grep "hold"`? – heemayl Mar 24 '15 at 18:51
  • @heemayl There is no output, which I think means that I have not manually placed a hold on the `lxc-docker` package. Any suggestions? – modulitos Mar 24 '15 at 22:03
  • @DavidFoerster Wow, that did it! I should have thought of that. `apt-get install lxc-docker` ended up removing `lxc-docker-1.4.1` and installing `lxc-docker-1.5.0`. It's rather odd that this wasn't included in the upgrade or dist-upgrade. Feel free to post an answer and I will happily accept it! – modulitos Mar 26 '15 at 18:59

You can upgrade lxc-docker specifically:

sudo apt-get install lxc-docker

That should override whatever holds back the upgrade (barring manually held packages, which we excluded in this case).
