Docker not installing

[pcs333]

Hi
I'm trying a new setup and after running setup and installing sonarr etc I realised docker was not installed.
Getting the error below

Ign:5 https://download.docker.com/linux/ubuntu cosmic InReleaseErr:6

https://download.docker.com/linux/ubuntu cosmic Release

404 Not Found [IP: 2600:9000:2006:3200:3:db06:4200:93a1 443]Reading package lists... Done

I have ubuntu 18.10 installed.
So now i am re-installing with 18.04 to see what happens ;-)

Works fine on 18.04

Ugh, don't tell me they will be changing things once AGAIN for 18.10 😝
Ah well we'll cross that bridge when we need to 😆
