Question

我在桌面上运行Ubuntu 16.04。我使用docker-ce，直到几天前它一直在工作。 Ubuntu中的自动更新似乎已将其破坏。

robert@catness:~$ docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

我尝试按照https://docs.docker.com/install/linux/docker-ce/ubuntu/上的说明进行删除和重新安装，但没有成功。

robert@catness:~$ sudo apt-get install docker-ce
Reading package lists... Done

docker-ce is already the newest version (5:18.09.0~3-0~ubuntu-xenial).
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies.
 docker-ce : Depends: containerd.io but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

我认为问题出在containerd.io。命令sudo apt-get -f install尝试安装它，并且出现以下错误：

The following additional packages will be installed:
  containerd.io
The following NEW packages will be installed
  containerd.io
0 to upgrade, 1 to newly install, 0 to remove and 1 not to upgrade.
1 not fully installed or removed.

After this operation, 87.6 MB of additional disk space will be used.

/ usr / sbin / runc出现了一些问题，作为调试的一部分，我尝试删除该文件，但这完全没有区别：

robert@catness:~$ ls /usr/sbin/runc
ls: cannot access '/usr/sbin/runc': No such file or directory
robert@catness:~$ sudo ls /usr/sbin/runc
ls: cannot access '/usr/sbin/runc': No such file or directory

有人对我下一步要调查此问题有什么建议。

Answer 1

我将删除 runc 软件包。 docker1.13.1 版本是指向非常老旧且不受支持的Docker版本的指针，因此这很可能是以前的升级遗留下来的。然后，您应该能够安装 containerd.io 。

您可能必须先使用 apt-get remove docker-ce 删除docker-ce软件包，然后执行 apt-get remove runc ，然后再次安装docker-ce您必须使用 apt-get install docker-ce 。这是因为尝试在不先删除docker-ce的情况下删除runc不起作用

让我知道这是否成功，因为如果一个人不存在，我想为此在docker中打开一个问题。
