Ubuntu 16.04 latest update broke Docker (docker-ce)

  • A+

I run Ubuntu 16.04 on my desktop. I use docker-ce and it has been working up until a few days ago. The auto-update in Ubuntu seems to have broken it.

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

I tried following the instructions at https://docs.docker.com/install/linux/docker-ce/ubuntu/ to remove and reinstall but it hasn't worked.

robert@catness:~$ sudo apt-get install docker-ce Reading package lists... Done Building dependency tree        Reading state information... 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). 

I believe the issue is with containerd.io. The command sudo apt-get -f install tries to install it and this errors:

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.

[Y/n] Y (Reading database ... 523620 files and directories currently installed.) Preparing to unpack .../containerd.io_1.2.0-1_amd64.deb ...

There was some problem with /usr/sbin/runc, as part of debugging I tried deleting the file there, but this has made no difference at all:

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 

Does anyone have any suggestions as to what I should do next to investigate this issue.


I'd remove the runc package. The docker1.13.1 version is a pointer to a very old and unsupported version of docker, so this is likely left over from a past upgrade. Then you should be able to install containerd.io.

Let me know if that's successful as I'd like to open an issue in docker for this if one doesn't already exist.
