Unable to locate package at install

From a customer in https://gitlab.zendesk.com/agent/tickets/82627:

I'm having problems installing gitlab-runner on an Ubuntu 16.04.3 LTS machine hosted at DigitalOcean.

First I followed the recommended apt repo instructions (https://docs.gitlab.com/runner/install/linux-repository.html) and got "Unable to locate package gitlab-runner".

$ sudo apt-get install gitlab-runner Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package gitlab-runner

>And then I tried manually installing but got a "403 Forbidden" error.

>```bash
$ sudo wget -O /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-amd64

After a bit more digging I've found that none of the /latest/ or /[tag]/ download URLs seem to work, but I've been able to get it working with /master/.

Assuming this is a problem on your end?

I've reproduced the problem in the following system:

vagrant@default-ubuntu-1604:~$ curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.deb.sh | sudo bash
.
.
.
The repository is setup! You can now install packages.

vagrant@default-ubuntu-1604:~$ sudo apt-get install gitlab-runner
