Guys, thanks so much. I did
read the instructions but I got thrown by this line:
This directory contains a subdirectory called "DEBS". Change directory to the "DEBS" directory.
That seemed like double-talk to me and I figured there had to be an easier way. Hence I thought of the GDebi installer.
Anyway, I decided to go back and uninstall the version I had attempted to install and get the Libreoffice from the Ubuntu Software Center (which I probably should have done in the first place).
Thanks for all the help and sorry for all my thick-headedness.
