apt-get update query

Trying to load 3.5.13.1 on a friends machine so add deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-v3.5.13/debian squeeze main deb-src http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-v3.5.13/debian squeeze main deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-builddeps-v3.5.1… squeeze main deb-src http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-builddeps-v3.5.1… squeeze main to sources.list then apt-key adv --keyserver keyserver.quickbuild.pearsoncomputing.net --recv-keys 2B8638D0 goes on OK then apt-get update shows the other repositories but not any trinty ones. Installation does not work Other machines with Trinity loaded do not show Trinity repositories although they do show new Trinity stuff with apt-get upgrade and Synaptic. Any ideas? John Campbell
