Advanced Search C Drive

I guess the subject really says it all... I have a PPC laptop that I have installed Ubuntu Servver 6.06 on it.
When I try to get the drbl files, I receive the error:
failed to fetch http://free.nchc.org.tw/drbl-core/dists/drbl/Release Unable to find expected entry stable/binary-power-pc/Packages in Meta-Index file (malformed Release file?)
Reading package lists... Done
E: Some index files failed to download, they may have been ignored, or old ones used instead

So I tried the apt-get install drbl command
Reading Package Lists... Done
Building Dependency Tree... Done
E: Couldn't find package DRBL

Any suggestions?
