Excellent guess! So… I rarely use pip, so those bits took a few tries…
Anyhow;
bcm2709_/root# apt install python3-pip -y
python3-pip is already the newest version (23.0.1+dfsg-1).
bcm2709_/root# apt install libfreetype6-dev
The following NEW packages will be installed:
libbrotli-dev libfreetype-dev libfreetype6-dev libpng-dev libpng-tools
bcm2709_/root# exit

And all the .png files showed up in ~/weewx-data/public_html with the rest
of the .html’s.
So, I checked several of my RPi’s, mostly running RPi-OS Bullseye, and it
was a mix of what I found with:
apt search libfreetype6
So… it sounds like this needs to be a dependency check somewhere. “apt
search libfreetype6” certainly isn’t the fastest
to return results. Hope that helps.
Thx as always, Chris
