I'm on Ubuntu 18.04LTS, which is based on Debian 10 (/etc/debian_version =
buster/sid). So, I would have thought that it should be there. Anyway, I
did install it with pip3:
$pip3 install cheetah3
...
Successfully installed cheetah3-3.2.5
and it still won't allow me to install the python3 version of weewx
$ sudo apt-get install weewx
...
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
...
The following packages have unmet dependencies:
weewx : Depends: python3-cheetah but it is not installable
E: Unable to correct problems, you have held broken packages.
So, I'm not sure what's happening. Well, I think I'll use this an excuse
to update to ubuntu 20.04LTS. Maybe the problem will fix itself with the
OS upgrade.
