This issue has been solved. I didn't change to trusty when I updated Ubuntu.
I now have the following lines in my /etc/apt/sources.list file: deb http://cran.utstat.utoronto.ca/bin/linux/ubuntu trusty/ and deb http://mirror.pnl.gov/ubuntu/ trusty-backports main restricted universe I also installed the keys described on http://mirror.las.iastate.edu/CRAN/ but I'm not sure if I needed them or not. Thanks for the help. Austin On Sat, Jun 13, 2015 at 5:33 PM, Michael Rutter <[email protected]> wrote: > Austin, > > You need to cc r-sig-debian in order to see the replies.
