Failed to install R14 on PCLOS

I am using David Hare's excellent Exe but also wanted to try R14 on PCLinuxOS as I am a long-time fan of that distro. I found instructions to install at: https://wiki.trinitydesktop.org/PCLinuxOSInstall I did wonder, could it really be that easy? Well, apparently not. Unfortunately, but not totally unexpected. I have found computers and computing to be an incredible time sink. :-) I received error messages ending with these: === Hit http://ftp.nluug.nl pclinuxos/32bit/xfce4 release Err http://ppa.quickbuild.pearsoncomputing.net trinity-r14/RPMS/i386 pkglist 404 Not Found Ign http://ppa.quickbuild.pearsoncomputing.net trinity-r14/RPMS/i386 release Hit http://ppa.quickbuild.pearsoncomputing.net trinity-r14/RPMS/noarch pkglist Hit http://ppa.quickbuild.pearsoncomputing.net trinity-r14/RPMS/noarch release Failed to fetch http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity/rpm/pclinuxos/tr… 404 Not Found Reading Package Lists...

[root@localhost andy]# === Any help appreciated. This is my first time attempting this so I am a complete novice; very complicated or technical info would be lost on me. I did visit the repo link listed in the installation instructions using Firefox, http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity/rpm/pclinuxos/ (which was redirected) and saw "pkglist.i586", etc., but nothing for i386. I'm not sure what "noarch" means, but that was also there, but no i386. Is that the problem or did I do something wrong? I attempted several times, but of course I did much the same thing each time so if I'm doing something wrong I just repeated it. Thanks for reading, Andy
