strange we got a 404 downloading one of the packages:

error: could not download 'https://ziglang.org/builds/zig-linux-x86_64-0.14.0-dev.2465+70de2f3a7.tar.xz': the HTTP server replied with unsuccessful response '404 Not Found'

probably a temporary problem (looks like it's working now on master: https://github.com/marler8997/zigup/actions/runs/13330938692)

Other problem is the CI is looking for the PDB on windows. We could exclude the PDB but is there a way we can still keep it around?

error: path 'zigup.pdb' is not found

I think this is happening due to the strip option, I am not very familiar with windows, but from what I have searched, a .pdb is a file that holds debug information, right? And since the stripping process removes debug info, it might be it.

If keeping debugging information on windows is useful, we could set strip to false when build target is windows, what do you think?

From a cursory look it looks like setting strip to true means no pdb. That's ok though, not a big deal. I've pushed a commit to your branch that removes the PDB, we'll see how the CI does with it.

Since the CI seems to be working fine now, I will mark the PR as ready for review, and then if anything new seems wrong, we can keep working on it!
