apt-get upgrade：为什么 lxc-docker 被保留？

Question

为什么 lxc-docker 被阻止？我还注意到我的 Web 应用程序在 Docker 上运行，速度很慢。有什么建议？

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.

请注意，我已经运行了sudo apt-get dist-upgrade，这并没有解决这个问题。因此，我不认为我的问题是这些问题的重复

Answer 1

您可以lxc-docker具体升级：

sudo apt-get install lxc-docker

这应该覆盖任何阻碍升级的东西（除了手动保存的包，我们在这种情况下排除了这些包）。
