Thanks for the contribution @ruffsl ! Would you mind rebasing your branch on the latest from master?

Note that it needs to be a rebase, not an "update". After a rebase there should still only be one commit in your branch, and no merge commits.

Would you mind amending your commit message to include Change-type: patch in the footer?

Also I suggest looking at this commit as an example as there may be some dependencies files that need updating.

as there may be some dependencies files that need updating.

I'm not sure how to go about this. Is there a script of some sort to auto update those partial templates here?

[ruffsl]

ping @klutchell , PR rebased. Looks like CI is passing.

Great! I think the only thing that is missing now is the custom templates for ubuntu@noble.

A good starting point is to look at the existing templates for jammy, and create an identical corresponding template for noble.

./contracts/sw.os+hw.device-type/ubuntu@jammy+raspberrypi400-64/dependencies.tpl
./contracts/sw.os+hw.device-type/ubuntu@jammy+coral-dev/dependencies.tpl
./contracts/sw.os+hw.device-type/ubuntu@jammy+raspberry-pi2/dependencies.tpl
./contracts/sw.os+hw.device-type/ubuntu@jammy+raspberrypi3-64/dependencies.tpl
./contracts/sw.os+hw.device-type/ubuntu@jammy+raspberrypi0-2w-64/dependencies.tpl
./contracts/sw.os+hw.device-type/ubuntu@jammy+raspberrypi4-64/dependencies.tpl
./contracts/sw.os+hw.device-type/ubuntu@jammy+revpi-core-3/dependencies.tpl
./contracts/sw.os+hw.device-type/ubuntu@jammy+raspberrypi3/dependencies.tpl

Then a quick check to see if the names of any packages in those templates have changed between jammy and noble.

Once that is done I can open a draft PR on the base-images repo to point to your contracts branch and see if everything generates!

[ruffsl]

Ok, I've duplicated the templates for ubuntu@noble. None of the package names seems to have changed, including:

Thanks for the contribution! Next we can wait for the auto-bump of this contracts change in the base-images repo and try a manual deployment of some of the new images for testing.
