eliran [1] filed a deletion request for gtk-theme-windows-server-2003 [2]: The Windows Server 2003 repository seems to be missing for B00merang- Project on GitHub. A Windows Classic theme from a neighboring repository is downloaded instead which naturally raises a hash mismatch error. I found that a Windows Server 2003 theme can be found in the Windows-95 repository of the same user at https://github.com/B00merang-Project/Windows-95/
Please consider updating or deleting this package [1] https://aur.archlinux.org/account/eliran/ [2] https://aur.archlinux.org/pkgbase/gtk-theme-windows-server-2003/
