Hello something is definetely odd on my installation apt-get asked me to autoremove a lot of files, I said yes without thinking too much and my trinity control center disappeared. So I run sudo apt-get install kubuntu-desktop-trinity but I obtain Err http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-v3.5.13/ubuntu/ lucid/main libkmime2-trinity 4:3.5.13-1ubuntu0+ax3~lucid 404 Not Found etc etc This looks very bad. I tried of course apt-get update but it did not help this is in my source.list file (as indicated in the wiki) deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-v3.5.13/ubuntu lucid main deb-src http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-v3.5.13/ubuntu lucid main deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-builddeps-v3.5.1 3/ubuntu lucid main deb-src http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-builddeps-v3.5.1 3/ubuntu lucid main what is now the problem, because 2 days ago the installation went smooth.
