teleport@16 (new cask)

[timhillgit]

This PR introduces a versioned cask of Teleport from https://goteleport.com/ . Homebrew already has the newest version of this application as a cask. However, teleport operates with both a server and a client. A server with an old version (e.g. 16, this cask) won't accept a connection from a client with a newer version (e.g. 17, the most recent). So it would be useful to be able to install an older version of the client.

Important: Do not tick a checkbox if you haven’t performed its action. Honesty is indispensable for a smooth review process.

In the following questions <cask> is the token of the cask you're submitting.

After making any changes to a cask, existing or new, verify:

• The submission is for a stable version or documented exception.
• brew audit --cask --online <cask> is error-free.
• brew style --fix <cask> reports no offenses.

Additionally, if adding a new cask:

• Named the cask according to the token reference.
• Checked the cask was not already refused (add your cask's name to the end of the search field).
• brew audit --cask --new <cask> worked successfully.
• HOMEBREW_NO_INSTALL_FROM_API=1 brew install --cask <cask> worked successfully.
• brew uninstall --cask <cask> worked successfully.

Hmm, CI on teleport is failing because teleport@16 doesn't exist. Which is true, it doesn't yet. I'm assuming we'd still want to merge this as is but I can split up the PR if that's easier.

Does teleport support this version of their platform still?

15 is eol this month, and 16 is not yet, few months more.

[SMillerDev]

Should have a disable! then

Does Teleport 16 receive any updates, or is it just support until September 2025?

[timhillgit]

I don't believe there are any minor updates planned, but there could be patch releases.

We will need to split the teleport changes into a followup PR.
