Trying to do the following always fails:
wget https://freefilesync.org/download/FreeFileSync_10.23_Source.zip
The repo currently downloads FreeFileSync from a mirror, as evidenced in https://github.com/flathub/org.freefilesync.FreeFileSync/blob/master/org.freefilesync.FreeFileSync.yml but I'd be more comfortable downloading it from the original source location.
Thank you.
