The link is old and dead, it would be best to remove the repo.
Just download/install the latest version (8.1.1) of AdobeReader for Linux;
http://www.adobe.com/products/acrobat/readstep2.html
Get the rpm version, to install type as root from where the downloaded file resides;
rpm -Uvh AdobeReader_enu-8.1.1-1.i486.rpm
