Snapcraft: Redirect all snapcraft.io links in CLI messages

[medubelko]

Background

Earlier this year, we fully migrated the Snapcraft docs from snapcraft.io/docs to documentation.ubuntu.com/snapcraft.

The CLI messages weren't updated during the migration. Several of them still contain links to snapcraft.io.

This will affect the behaviour of Snapcraft itself, so this would be a good opportunity to make a low-risk change to a product's code!

Request

Update all the references to snapcraft.io/docs in the CLI code to instead point to the corresponding pages in documentation.ubuntu.com/snapcraft.

Run the integration test suite, and test the build for yourself.

Guidelines

Before you begin, review the Snapcraft contribution guidelines.

Many of these pages were renamed, and the URL patterns are different, so you'll need to account for any differences. The redirection map of snapcraft.io to RTD pages is in the snapcraft.io repo.

Some pages were retired during migration. If a CLI command links to one of those pages, consult with me or @jahn-junior to determine a good replacement.

@medubelko I would love to work on this issue.

Firstly, I would work on updating all the old references of ssnapcraft.io/docs to the new reference documentation.ubuntu.com/snapcraft.

Howvever, am not so clear on what you meant about: If a CLI command links to one of those pages that has been retired.

Could you provide more highlight on this?

Hi @KrownWealth, I've assigned this item to you. For faster discussion, it's easier to reach me on Matrix. You can find me through the public CODA room.

Could you provide more highlight on this?

Of course! Some of the links on https://snapcraft.io/docs/ were taken down, and now redirect to the home page of https://documentation.ubuntu.com/snapcraft. That means the page no longer exists, and has no modern replacement (= retired). If a CLI message contains a link to a retired Discourse page, we need to determine whether to provide an alternative, or whether the link should be removed.
