I've been trying to solve this issue recently and have some inquiries on my mind. Is it similar to the functionality of git clone? Could you offer alternative resources or links beyond what's provided in the documentation that can be used with kraft pkg pull?

[craciunoiuc]

There are two methods, ssh and http

With ssh, it's only git, with http it's archive + git.

Git-way means it uses a go-git library to fetch sources with history.
Archive-way means you just fetch files for a given tag/branch like you would do from the github UI.

status update:

This happens because the package name needs to be used and that one does not match the url provided, so further investigation is needed
