Comment 11 for bug 1926938

I built a container for building mainline kernels. It build debs by default, but it can also build signed source packages, but unfortunately the sources are too big to be used with a PPA (they fill up the disk during build).

There is another issue with building mainline on focal, and that's the kernels require pahole >= 1.16 (from dwarves package). The groovy version of dwarves can be installed on focal, or you can use my PPA here: https://launchpad.net/~tuxinvader/+archive/ubuntu/lts-mainline

I was hoping to push my kernels to that PPA, but as I said - they're too big for launchpad.

If you want an easy(ish) way to compile your own mainline packages you can use this: https://hub.docker.com/r/tuxinvader/focal-mainline-builder
