I run two versions on Ubuntu.
One native on an Atom PC and the other in a VMWare virtual machine using an Ubuntu VM appliance.
Everything worked but I could never get Graphs to load the images and it seems it was a well known problem with collectd and Ubuntu 20
I came across this thread and ran both
echo "LD_PRELOAD=/usr/lib/python3.8/config-3.8-aarch64-linux-gnu/libpython3.8.so" | sudo tee -a /etc/default/collectd
sudo systemctl restart collectd
and they are now both working happily.
I wholehaeartedly agree.
