I think this branch was pulled before your PR merged. Needs a bit of conflict resolution then you can work the patch. I'd expect howto/bugs.rst from main doesn't contain a GitHub Issues: link name.

Sorry for suggesting this earlier.

Turns out I don't think sphinx supports name reference link sharing as it does with document anchor :ref:s.

We'd either need to embed the link directly like so:

Suggested change

	2. `Report an upstream cloud-init bug<open issues>` on GitHub.
	2. `Report an upstream cloud-init bug <https://github.com/canonical/cloud-init/issues>` on GitHub.

or just use separate "named links" in LINKS: as we currently have in the file anyway.
Let's defer to use what we have and avoid inline representation of links. I prefer if we are all down in designated LINKS: section for readability.

I think sphinx isn't going to support the named LINKS: sharing as it does with :ref:. So let's still with the unique/duplicated named links instead of inline link definitions.

Thank you for this @holmanb but I think duplicated LINKS: is better than inline link definitions at the moment. If you disagree we can go for inline links or a different approach and re-open this PR.
