Path `GAP.jl/` exists and looks like the correct package. Using existing path.

Thank you for taking the time to report this. However, there is really nothing we can do about this: the file being downloaded is hosted on GitHub, so any unexpected 404 error is due to GitHub having a (hopefully temporary) issue, and/or something on the network is having an issue (e.g. your ISP, firewall, etc.). Moreover, the download is performed by Julia, so we have no control over that in any way either (e.g. to force a retry or something like that).
