Let's say you're using Ubuntu 13.04 (Raring Ringtail, released in April 2013) and it just went End-of-Life on you, because it's supported for only 6 months, and the deprecated packages are taken down after 12 months.

You'll probably figure this out the hard way. When you run sudo apt-get update, it will eventually report these errors:

Ign http://archive.ubuntu.com raring-updates/universe Sources/DiffIndex
Err http://security.ubuntu.com raring-security/main Sources
  404  Not Found [IP: 91.189.91.15 80]
Err http://security.ubuntu.com raring-security/universe Sources
  404  Not Found [IP: 91.189.91.15 80]

When hotfixes need to be applied and deployed to production:

Make sure that the hotfix branch is branched off from the production branch and not the development branch.
Send a pull request for the production branch. The production branch isn't protected for merges like the development branch, so you can merge them yourself (useful in cases of emergency and no one us there to approve your PR) but if possible, as someone to merge the code for you.
Send a pull request to the development branch so the pull request exists in both branches.
In case the PR does not merge cleanly with development please branch off from the hotfix branch, fix the merge conflicts, and then merge that into development

Note that the production branch doesn't need to have its own canonical history; only development has that property. This means that in case the production branch becomes fully out of sync with development it is not forbidden to just delete "bad" production branch and just recreate i
