Hello,

sage -p THE_PACKAGE

is the *good* way. But there is a permission problem related to your Sage installation. How did you install Sage by yourself? You used the ubuntu ppa?

A sided remark: if you are working within the repository /tmp/ with Sage you will always get into troubles.

in Ubuntu.

I downloaded the package as a zip file and unzipped it. I then changed into
/home/user/abelfunctions-master and ran

tar cjf abelfunctions.spkg
/home/user/Downloads/abelfunctions-master/abelfunctions/

I then tried

sage -p -c abelfunctions.spkg

but it complained

Error: no write access to build directory
/usr/lib/sagemath/local/var/tmp/sage/build.

So I tried

sudo sage -p -c abelfunctions.spkg

What is the correct way to install this package?
