16.04: No texhash? Adding .cls files

[trinityman]

I tried to run sudo texhash in advance of installing a cls file, and the command is not found. Additionally, I have no idea where the texmf tree is (kpsewhich -var-value=TEXMFHOME gives me /home/username/texmf, which does not exist), so I don't know how I can install new packages or class files. TeX Live Manager does not work after install either.

• I have it in /opt/texbin/texhash. The scripts should add /opt/texbin to your $PATH in /etc/environment.
• You can create the directory /home/username/texmf/tex/latex and copy the cls file there
