Using the normal apt upgrade command I have had a bit of a party upgrading to Version 4.1.1-1 with missing Python 3 Modules in particular python3-serial, python3-configobj, python3-mysqldb, python3-pil this last one causing the graphs not to be created, I am left with this error:

Should I be concerned? I have searched with apt search cheetah and found that I have python-cheetah/oldstable,now 2.4.4-4 armhf [installed]

No python3-cheetah though.

Install python3-cheetah.

(python-cheetah is for Python2)

You did not say what operating system you are using, but python3-cheetah is not available on all systems. In particular, it is not available for Debian 9.

In that case, you must either use Python 2, or use pip to install a python3 version of Cheetah.

sudo apt install python3-distutils
sudo apt install python3-pip
sudo pip3 install cheetah3
