I am unable to install NaSC the math for humans software from elementary OS.
The terminal gives the following errors:

Hi,
firstly, you have “broken packages”, to fix that, run the following terminal command (Ctrl +Alt + t):
sudo dpkg --configure -a
followed by
sudo apt-get install -f
“unmet dependencies”, to cure that, try changing your software sources download location to “Main server” (Where it states “Download from”).
Update your system sources list with:
sudo apt-get update
You can look for the packages here if the above doesn’t help and install them before you try and install the package (NaSC) again (make a note of the package name and search for the Ubuntu packages!):

Let us know how you get on!.

Please do
sudo dpkg – configure -a
sudo apt-get install -f
the problem is package dependencies
please install libgranite stable version
