I am trying to install Docker inside a virtual machine running debian stretch that i was provided access to by my company. Searching through forums i read many posts claiming this is working out-of-the-box.
However when following installation guides (i tried the official docker installation guide for debian as well as a docker installation guide from digitalocean getting the same results) i run into the same errors everytime when i install docker-ce with apt.
Error looks like the following (sorry, the system has german localization):
update-alternatives: Warnung: Neuinstallation der Alternative /usr/bin/dockerd-ce ist erzwungen, weil Linkgruppe dockerd defekt ist
Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xe" for details.
invoke-rc.d: initscript docker, action "start" failed.

Perhaps iptables or your kernel needs to be upgraded.

I have already rebooted multiple times and checked that iptables is there before installing docker.
How can i make it work?
