Hi,
thank you for the report, the git://git.proxmox.com/git/mirror_ubuntu-kernels was slightly behind, so it didn't yet contain the newest required tag. The issue should be fixed now thanks to @fabian!
What distro can I use to build kernels? Right now I'm using proxmox itself, latest, which looks to be working well, but I assume you build on a debian distro. Can you share what version if so? Debian 13.5?
Found the dev pages so will follow that. Thanks again for the fix.
