Error: failed retrieving file when trying to install bottles

[TNE]

In general, errors like these can be expected, but even these should be fixed now. In this case, pacman will simply pick another mirror in the mirrorlist.

The issue in the original post is that the download of a .sig file failed, which is a bigger deal, but that should be fixed now:

From r2.garudalinux.org : The requested URL returned error: 404 | Ok I am stupid,so can I get step by step the way fix this

This issue has now been fixed. The cause was a faulty regex on the chaotic-aur router level that existed there for months now, but only actually became an issue ever since r2 launched for Garuda. Should be all good now, give it a go!
