Select alternative apt mirror to get around the unstable original one

[rake5k]

This should fix #4.

Since this issue hits me in about every month's time, I ran a quick research on the root cause (e.g. actions/runner-images#7048).

The downside of this solution is clearly that we rely on an extra package (apt-spy2). That installation and the repository update take a few additional seconds to complete. But in my very personal case, the gained resiliency is definitely worth it.

I hope, this helps others too.

Thank you so much @rake5k!

I hope you won't mind me asking you a few questions:

• Do you think this should be an option? Maybe a allow-apt-mirrors that defaults to true but can be set to false if needed for some reason?
• @kfir4444 submit PR #8 also under consideration, which makes the point that these statements can cause the action to terminate when they fail.
  • What happens if the installation of the package, sudo gem install apt-spy2, fails?
  • Can this line fail too? sudo apt-spy2 fix --commit --launchpad --country=US
• In the line sudo apt-spy2 fix --commit --launchpad --country=US, I notice that you hardcode the country. Presumably this would force the wrong mirrors to be picked for a user in say, East Asia. Maybe instead of using an option allow-apt-mirrors, there should be a apt-mirror-country that defaults to US, that can be changed to other countries — and when it is empty, the apt-spy2 feature is not turned on?

Thanks so much for your contribution!

[rake5k]

Good questions, @jlumbroso!

• It might be a good idea to make this feature an opt-out one, I highly agree. To keep the action's configuration interface simple, I did not come up with it in the first iteration.
• Good catch! The error handling is just not there yet. I will bring up one, just let me know if I should invest in that as Allow fails in Remove large packages #8 would definitively be a viable solution in my opinion, since it does not bring in additional complexity like this one here.
• Honestly, this change absolutely relies on naïvely trusting on some comments inside somewhat related GitHub issues. I did a quick research and found that the GH runners are actually located in the US. Therefore, hard-coding the country can be ok, even if it would be better to get that information dynamically, as this might change in the future.

Thank you a lot for this GH action, I heavily rely on it 🙏🏻

Hello @rake5k,

Just wanted to follow-up and see why you had closed this PR?

I think the option of picking a different mirror for the packages is still a useful one, but I was looking into adding the configuration we discussed:

• setting to turn on/off alternate mirrors (defaults to "false")
• setting to select country code (defaults to US)

Do you not think this feature is useful anymore?

Thank you!

[rake5k]

Hi @jlumbroso,

Please excuse my unexpected closing of this PR, I thought it was not relevant anymore after merging #16. If you are still considering this change, I will implement your suggestions, of course. This weekend I am a little busy though, I hope to get on it soon (next week probably).
