Problem:

I can not install the latest Adobe flash plugin (version 10) in Asianux 2.0 SP3.

Reason:

The latest version of Adobe flash plugin (version 10) is designed for new systems shipped with glibc > 2.4.  Asianux 2.0 SP3 is not a new system, it is the update of Asianux 2.0 and does not provide glibc > 2.4, so you have to install a previous version of flash plugin.

Solution:

You can download version 9 from below URL, it works with Asianux 2.0 SP3.
