I'm currently working on a project that utilizes compiling an embedded Linux image using BuildRoot for a BeagleBone Black OBC, and am pulling my hair out for an issue I don't know how to approach to solve.
The Linux project I am trying to build is called KubOS, and like I mentioned is using BuildRoot v2019.2.2. I've followed the required steps for generating the makeconfig file for my particular board, and for the first half of the build process everything seems to be fine.
Unfortunately, when trying to build some of the packages that are included in the final build, I reach a point where BuildRoot is trying to find a dependency that no longer exists.

Initially, it asks for my GitHub credentials, which I have confirmed are correct, and once entered it fails to clone the repository due to missing a "personal access token". I understand that this means it needs an ssh key registered to my GitHub account, so I've generated an SSH key for my user and registered it, and can confirm I am able to clone repositories using that account. However, repeating the process to clone it still fails, and through following the git repository link that it's trying to pull (https://github.com/osakared/qwt.git/), it appears that it has been removed at some point by the author. and cannot be found.
My question: How can I remove the package from BuildRoot so that it does not compile it in the final image, or how can I point BuildRoot to another git repository it can use instead?
I'm at odds with how to start solving this issue, as I do not have enough experience with BuildRoot and compiling Linux images from scratch to figure out where to start looking. I have searched through both the KubOS project and BuildRoot files to find where this package is defined and if I can change its reference to some other repository or even remove it, but have been unsuccessful.
I'd be happy to add any more details in future edits if they are needed.
