help for AdmIRC

I installed centos with webmin hours I install the server irc but if I go in modules webmin and I try to install AdmIRC me returns this :

Installing the module non riuscita : Archive module Invalid : tar: This does not look like a tar archive tar: Skipping to next header tar: Read 8830 bytes from /tmp/.webmin/showfiles.php?group_id=79267 tar: Error exit delayed from previous errors

what can I do?

That URL points to a download page–not the actual module. You need to keep clicking until you get to the page where it allows you to select a link that mentions a "direct link". For example, the file you need can be downloaded from:

This link may not be the best mirror for you, but it’s a small file, so probably fine, no matter where you are.

Ok thanks hours trying
