Hello!
It appears as if Amber is on it's way. What is Amber? Amber is the code name for the new stable version of PureOS. As one can see from the PureOS changes mailing list, Matthias has added Amber to debootstrap; https://lists.puri.sm/pipermail/pureos-changes/2019-August/000414.html I look forward to testing it on my Librem 15. I've already tested it a bit in a Docker container (see deets in pureos-dev chat on matrix.)
Speaking of the PureOS changes mailing list, there is now a bridge from Laniakea to Matrix. Ask Matthias or myself for an invite.
In discussing the new Buster based version of Amber internally, I note that there continues to be interest in having Green be the stable version of PureOS. I worry that if we don't use Green, lots of users who would benefit from stability will get a huge update once we move back to a rolling release. Right now, using a Docker image of an updated Green, I note there are 114[0] packages waiting to be updated if I switch over to Debian Testing, and that is just for a minimal image. I imagine those who have a lot more packages installed will see a lot more updates. This might get messy quickly.
Fortunately I beleive that Matthias and I have a plan that will work and be minimaly invasive to users. The plan is to _append_ the various Amber suites to /etc/apt/sources.list and have users update that way.
There are some new Docker images for 'green' and 'landing' available here: https://cloud.docker.com/u/pureos/repository/docker/pureos/green I plan to create one for Amber and Purple as well. I'm automating the process to build these images since updated images will likely get consumed in other parts of our CI/CD.
Lots of testing coming up to ensure Amber is easy to update to.
Feedback most welcome.
Cheers,
Jeremiah
