That download is an old beta release compiled for an old version of RedHat. I may be wrong but I don't think it would be likely to work with Sid and since Adobe is ending support for that reader in 2 years it is unlikely you will see a new version for Linux. Also, I believe that RedHat used Gnome by default and that could also bring about compatibility issues with KDE. Sorry for the bad news.

Good news though, you may be able to get this working with Firefox. Try this
LINK. Let us know if you get it working.
