When I accidentally typed the FTP server name in capital letters during upgrade,
anaconda complained that it contains invalid characters. Is there any reason for
it to do that?
I could not reproduce this behavour. Could you explain in more detail the screen
you are entering the server name into, as well as the exact server name you used?
I typed FTP.BETA.redhat.com. But may be something else went wrong - I didn't
attempt to reproduce it.
I also can't reproduce this. If you can reproduce it, please feel free to reopen
