Well I did some research and see I am/was not the only one having
trouble with the msttcore fonts. I tried some of the suggested ways I
read about but still getting the msttcorefont error. So I am asking
for any help or suggestions to fix this. Not sure if it is affecting
my packages I installed or not, but I guess if worse comes to worse, I
will wipeout Ubuntu and reinstall it, which I am not looking forward
to.
