sudo dpkg -i bsu_3.0.2-1_amd64.deb
If you wish to install on a 64 bit machine with Plplot, the command is:
sudo dpkg -i bsu_3.0.2-1+plplot_amd64.deb
If you wish to install static built executables (ONLY Gnuplot version), the command is:
sudo dpkg -i bsu_3.0.2-1+static_amd64.deb
These packages should work for both AMD and Intel cpu's. As an alternative to ”dpkg -i“, I recommend using the ”gdebi“ command, as it checks for dependencies. For example:
sudo gdebi bsu_3.0.2-1+plplot_amd64.deb
