Some Valid Versioning usage in External Feeds (GitHub Nuget) will result in Package Not Found in Feed

[millerjn21]

Prerequisites

• I have verified the problem exists in the latest version
• I have searched open and closed issues to make sure it isn't already reported
• I have written a descriptive issue title
• I have linked the original source of this report
• I have tagged the issue appropriately (area/*, kind/bug, tag/regression?)

The bug

Using a GitHub Nuget external feed, some versioning will result in The package was not found in the feed. An example of this is #.#.#-AAA-####-AAAAA-AAAAA.###. This versioning is valid semver, but Octopus fails to pull in the details of the package on the release page. However, the package still deploys correctly. I would expect this behavior is not limited to GitHub Nuget feeds, but that is what I discovered and tested it on.

What I expected to happen

I would expect the release page to be able to find the package and get the information.

Steps to reproduce

1. Create an external Nuget GH feed
2. Push a package with versioning like the above example or below screenshot.
3. Add the package to a step and create a release
4. See the error

Screen capture

Affected versions

Octopus Server: Latest at time of writing (2021.1.6460)

Workarounds

Change the versioning schema of your package or ignore the error, as the package will still deploy correctly.
