lts-mainline-longterm >=6.1.16 build failed

The builds are failing because the kernel build now requires rust packages which aren't available in Jammy, but they are being back-ported. The rust bindgen-0.56 package is currently in proposed. When that package makes it through to the universe repo I'll resubmit the latest kernel build.

This may be the end of the line for focal though.

Sadly. Does 5.15 now also require rust? I ask because from some version 5.15 on the focal stopped loading normally, the interface is there, but most of the peripherals do not work, because of this I had to switch to 6.1

Concerning focal the 5.15 kernel is officially supported via hwe so you do not have to build it your self or use the ppa

This may be the end of the line for focal though.

Even for 6.1? Were some rust dependencies introduced in the change from 6.1.15 to .16?

It looks like the bindgen package has arrived in jammy and 6.2.6 has had a successful build.

WRT focal: the early versions of 6.2 were built without rust, so I've updated the script to back-out those dependencies on 6.2 kernels for focal, and 6.2.6 is building now. I'm not sure what this will mean for 6.3 and newer kernels. It's likely that focal users will have to stick on the latest longterm series of 6.1.x, because the 6.2 kernel will only have a short support period.

In any case Jammy is the current LTS and it's been out for almost 12 months, it's time to upgrade people ;-)

The 6.1 kernel is the release that added Rust support, but the rust dependencies in Ubuntu kernels were added in the 6.2.3/6.1.16 time frame, so 6.1.16+ is also failing. I can remove the rust dependency from the 6.1 series kernels, and track that LTS as the final focal kernel. All newer kernels are going to require rust.

Looks simple. What are the pitfalls of this method?

@TuxInvader I tried to build the image on the last version of builder and still get the following error on the launchpad:

The following packages have unmet dependencies:
 sbuild-build-depends-main-dummy : Depends: rustc-1.62 but it is not installable
                                   Depends: rust-1.62-src but it is not installable
                                   Depends: rustfmt-1.62 but it is not installable
                                   Depends: bindgen-0.56 but it is not installable

What am i doing wrong?

I'm trying to build because I can't install the version from your repository, it gives an error about incompatible dependencies linux-generic-6.01 and linux-headers-6.1.19-060119-generic

[TuxInvader]

It should be fixed now. The change to remove the rust dependencies broke the rename process.The 6.1.19 package should be fixed on my PPA too.

[TuxInvader]

This is still an issue. The bindgen-0.56 package has not made it into universe yet, and is still in proposed for Jammy. I may need to disable rust in jammy while we wait for it to progress through the verification process. Ubuntu bug is here: https://bugs.launchpad.net/ubuntu/+source/rustc-1.62/+bug/1993183

@TuxInvader what happened with 6.1 builds for focal ?

[TuxInvader]

The Ubuntu repos aren't syncing the changes from mainline builds anymore so I had no working tags to checkout. I fixed the issue by adding support for kernel.org as a git source and applying the ubuntu crack.bundle. I need to update the docs and submit the changes to thise repo, but there are now images available.
