Hi Tim!
Thank you, I did
removed
/var/lib/apt/lists/ppa.quickbuild.pearsoncomputing.net_trinity_trinity*
and it works. Now I'm happy installing :-)

Great! I have also spoken with the trinity.lv mirror maintainer and he
has corrected the configuration issue, so the full mirror system will be
back online shortly.
Thank you for letting us know about the problem!
Tim
