Hi everyone, I tried to do an Ubuntu maverick install of trinity, and followed the instructions here : 1) added to sources.list : deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity/ubuntu maverick main deb-src http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity/ubuntu maverick main deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-builddeps/ubuntu maverick main deb-src http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-builddeps/ubuntu maverick main 2) sudo apt-key adv --keyserver keyserver.quickbuild.pearsoncomputing.net --recv-keys 2B8638D0 But then, apt-get update gives me : Ign http://ppa.quickbuild.pearsoncomputing.net maverick Release.gpg Ign http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity/ubuntu/ maverick/main Translation-en Ign http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity/ubuntu/ maverick/main Translation-fr Ign http://ppa.quickbuild.pearsoncomputing.net maverick Release.gpg Ign http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-builddeps/ubuntu/ maverick/main Translation-en Ign http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-builddeps/ubuntu/ maverick/main Translation-fr Ign http://ppa.quickbuild.pearsoncomputing.net maverick Release Ign http://ppa.quickbuild.pearsoncomputing.net maverick Release Ign http://ppa.quickbuild.pearsoncomputing.net maverick/main Sources Ign http://ppa.quickbuild.pearsoncomputing.net maverick/main i386 Packages Ign http://ppa.quickbuild.pearsoncomputing.net maverick/main Sources Ign http://ppa.quickbuild.pearsoncomputing.net maverick/main i386 Packages Ign http://ppa.quickbuild.pearsoncomputing.net maverick/main Sources Ign http://ppa.quickbuild.pearsoncomputing.net maverick/main i386 Packages Ign http://ppa.quickbuild.pearsoncomputing.net maverick/main Sources Ign http://ppa.quickbuild.pearsoncomputing.net maverick/main i386 Packages Err http://ppa.quickbuild.pearsoncomputing.net maverick/main Sources 404 Not Found Err http://ppa.quickbuild.pearsoncomputing.net maverick/main i386 Packages 404 Not Found Err http://ppa.quickbuild.pearsoncomputing.net maverick/main Sources 404 Not Found Err http://ppa.quickbuild.pearsoncomputing.net maverick/main i386 Packages 404 Not Found I surely must be missing something, but what ?
