The Sage you installed using sudo apt install sagemath uses the system Python.
So you can simply use
pip install package_name
Hopefully in the future we can make it so that
sage --pip install package_name
also works in the case when Sage is installed via a package manager such as apt,
or at least prints out a helpful message telling the user to use pip
instead of sage --pip or sage -pip.
