Removed lock after "could not get lock", now I get "post installation script was interrupted"

Question

I'm unable to remove lock from dpkg, and it seems docker-ce installation was stopped midway:

$ sudo rm /var/lib/apt/lists/lock
$ sudo rm /var/cache/apt/archives/lock
$ sudo apt install aptitude
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
$ sudo rm -R /var/lib/dpkg/lock
$ sudo rm /var/lib/dpkg/lock
rm: cannot remove '/var/lib/dpkg/lock': No such file or directory
$ sudo rm /var/lib/dpkg/lock
rm: cannot remove '/var/lib/dpkg/lock': No such file or directory
$ sudo rm /var/lib/apt/lists/lock
rm: cannot remove '/var/lib/apt/lists/lock': No such file or directory
$ sudo dpkg --configure -a
Setting up docker-ce (17.06.2~ce-0~ubuntu) ...
^Cdpkg: error processing package docker-ce (--configure):
 subprocess installed post-installation script was interrupted
Errors were encountered while processing:
 docker-ce

I have deleted lock files, but I get the same message. Using Ubuntu 16.04.

You already removed the package manager log but the package configuration was still interrupted. You need to reinstall the docker package from scratch with dpkg -i /path/to/package.deb.

This won't resolve the original issue of the Docker installation. Please open a new question for that and include the output of the installation command. Thanks.
