[Trisquel-users] Re : Verifying Trisquel download : md5 and sha256 OK, but GPG failed because key not found

The question remaining is why remove the execute permission from the files,  
and not from the directory.

You cannot execute a directory. For directory the "x" permission means  
"traversing the directory".

For more information on file permissions:
$ info File permissions
