first hurdle is actually building that code. https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1632072 makes it really hard for no apparent reason - i assume Ubuntu people never see this because it's been around for a while and always installed...

the other issue is missing dependencies in Debian. so far i have tried removing ubuntu-drivers-common from ubuntu-release-upgrader build-deps. the apt-clone dependency version is also too high in both source packages, 0.2.2 seems enough.

a rather naive patch, necessary because python-launchpadlib is missing from debian jessie:

with all of this, i could install the packages, but obviously, nothing is working:

probably a problem with the python-apt interface...

that's actually true: i'm running the latest debian stable (jessie), but i suspect it's not really doing what i think it should be doing. :) indeed, this is looking at Ubuntu-specific "meta-release" files:

obviously, something needs to come up that will make that work in debian. that, or it should be possible to hardcode a specific release to upgrade to manually.

i am rather surprised to see that the DistUpgrade library is shipped separately from the regular APT mechanisms. it also seems mandatory in the new do-release-upgrade script, which is unfortunate... it seems to me there would be room for a stable DistUpgrade library that would be shipped with every release normally, and maintained as usual.. hooks and other things could accomplish the deltas needed to settle any quirks.

anyways, i'm done looking at this for the day, but hopefully a future project will enable me to clean that up and merge this into debian eventually.

i have opened this discussion on debian's side of things as well: https://wiki.debian.org/AutomatedUpgrade

This is the issue that I faced when I was running https://bapehoodie.co/ project but then I took an informative article which helped me to fix this problem.
