Failed to fetch on fresh vagrant ubuntu 18.04 about ansible-docker HOT 6 CLOSED

That leads you down a pretty deep rabbit hole. Docker probably isn't the only role you're using. You may have 2, 5, or even 20 other roles that maybe potentially require apt installing a package.

If you put an apt-get update in all of them then it's going to drastically slow down your Ansible run because it takes a long time for that command to run. It's super inefficient to run that command 5 times within 2 minutes on a first run.

Ansible lets you solve this problem by configuring a cache time to avoid re-running until the cache expires, but now suddenly every role needs a configurable apt cache time. This is something I used to do 3-4 years ago but after working with many dozens of roles, I found this pattern to be a huge problem.

IMO it's a lot nicer to have the concept of a "bootstrap" role that does things like bootstrapping your server to run Ansible, enable Ubuntu's universe repos and do an initial apt-get update. Then it's all managed in 1 spot and you can let the system manage the internals of regularly running apt-get update if you want to keep things fresh.

Have you run an apt-get update on your server before?

It would be expected that you do.

I'm sorry, this is my first time with Ansible. Just curious, why isn't the apt-get update command specified in the role already?

I see, thanks for the explanation.
I've apt-get updated the vagrant server.
Now it stops at:

TASK [nickjj.docker : Install Docker] ******************************************
fatal: [machine1]: FAILED! => {"changed": false, "msg": "No package matching 'docker-ce' is available"}

The whole output is:

TASK [Install Docker and Docker-Compose] ***************************************

TASK [nickjj.docker : Disable pinned Docker version] ***************************
ok: [machine1]

TASK [nickjj.docker : Enable pinned Docker version] ****************************
skipping: [machine1]

TASK [nickjj.docker : Install Docker's dependencies] ***************************
changed: [machine1]

TASK [nickjj.docker : Add Docker's public GPG key to the APT keyring] **********
changed: [machine1]

TASK [nickjj.docker : Configure Docker's upstream APT repository] **************
changed: [machine1]

TASK [nickjj.docker : Install Docker] ******************************************
fatal: [machine1]: FAILED! => {"changed": false, "msg": "No package matching 'docker-ce' is available"}

I don't know what Vagrant box you're using, is it a 32bit of 64bit OS?

Also check this: #37 (comment) and read it until the end of the issue.

Closing this since it looks like you got past this based on your other issue without needing to modify anything in this role.
