r-base installation fails on Ubuntu 14.04
Problems are showing up with libgfortran3 and liblapack3.
Results of apt-cache policy are below. FYI no part of R is currently
installed on my system. Thanks.
root at bwud:/etc/apt# apt-get install r-base-core
...
The following packages have unmet dependencies:
r-base-core : Depends: libgfortran3 (>= 4.3) but it is not going to be
installed
Depends: liblapack3 but it is not going to be installed or
liblapack.so.3
Recommends: r-recommended but it is not going to be
installed
Recommends: r-base-dev but it is not going to be installed

If something 'blocks', do a 'apt-cache policy nameofthatpackage' to see where it came from. Worst case, uninstall components (carefully) as suggested here. By removing R and pieces you should not be able to brick your system. PPAs are great, but they are /not/ tested against each other as the distro core is. Dirk
