The version of botocore currently available in Debian stable (buster) is too old to know about IMDSv2. In order to continue deploying to Debian stable I need to build a stable backport from the version available in testing, so I thought I might as well go ahead and create an official one instead of just a local build. This seems like something that would impact a lot of users who are using AWS.
I was able to build the stable backports package by following the instructions here, but I can't upload it since I'm not a Debian Developer. I'm pretty new to the Debian contribution process, so could someone tell me what my next step(s) should be to get this backport rolling?
I tend to think you have done everything just fine. What you need now is a sponsor who uploads your package to Debian backports. I am CCing the Debian Cloud team where there should be someone with more of a context to it all and likely also a volunteer.
