S3 Perl Module

Hello, I use Virtualmin Gpl on 2 small servers with Debian9. For data backup I use the function under> Virtualmin> Backup other restore> Amazon S3

On the two servers, this works fine after installing Perl xml :: simple.
Now I have set up a new server and would like to use S3 again as a backup solution. After installing evon xml :: simple I receive the error message:

The Perl module S3 :: AWSAuthConnection needed to communicate with Amazon’s S3 service is not installed

This message came with no other server I have set up so far. I tried to install the module. But this module does not exist on Cpan.

In the forum I can only find posts from 2006 by this is described as a bug.

What can I do? Would be grateful for help
