Using the kernel manager configuration GUI to build a modified kernel from a template fails at the “Retrieving sources” stage. From my limited understanding, it appears to be throwing a 404 error when attempting to retrieve the relevant .asc signature file for the compressed archive.

It attempts to use 7.0.10-2 which is the previous release. The latest version is 7.0.11-1 which released yesterday. If it is simply failing to find the .asc file from the 7.0.10-2 release, presumably building from the 7.0.11-1 release would not cause this error because the .asc file is present for that release.

Initially I assumed it was a connection issue on my end, but I was able to successfully force-reinstall all packages (after clearing the package-cache). Which is presumably a much more network-heavy task. I have attempted to build this multiple times, a few hours apart, each time clearing the package-cache and making sure all packages are up to date. The template itself is unlikely to be a factor because it is the same one I always use, saved from Cachy’s own kernel manager program, and has worked perfectly for all previous builds.
My system is otherwise up to date but this currently leaves me without functional 3d graphics drivers, as I intentionally removed the builtin to avoid partial upgrade (the builtin open nvidia causes a recursive dependency whenever there is a graphics driver update).
I imagine there’s a saner method of avoiding partial upgrades than uninstalling the builtin, performing a clean upgrade, and then baking them back in to a new kernel every time there’s a graphics driver update. But I should probably ask about that in a separate topic.
