Mageia RPMS can't be added to the package manager

Hello,

I'm trying to add the Trinity desktop to a Mageia 2 installation, but the urpmi.addmedia command will hang for a minute or so and then fail thus:

[root@jupiter ~]# |urpmi.addmedia trinity-main-noarch http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity/rpm/mga2/trinity-...

adding medium "trinity-main-noarch"

...retrieving failed: curl failed: exited with 28

This has happened for all the repos listed on the Mageia install instructions page I've tried so far.

Looking at the package archives I've built for myself, the following files are missing from media_info:

changelog.xml.lzma files.xml.lzma info.xml.lzma

Any suggestions?

Thanks, Tim W
