The script is asking you to use apt-get, which is not a Fedora tool - Fedora uses dnf.
You might try "dnf install python3-i2c-tools", to see if it helps with the I2C
communications.
But really, the path of least resistance is to use the OS they wrote their
tools for.

Good advice. I tried but adding the uart option didn't work. I suspect we have
two problems overlaid. It coudl be a problem with the python version in

You can enable the serial port by adding this line:
enable_uart=1
in the file /boot/efi/config.txt and rebooting the Pi. If that doesn't
work for you, you might consider temporarily loading a copy of Raspbian on an
SD card just to do the fan setup, since that is what the hardware manufacturer
expects you to be using.
After configuring the fan, then put your Fedora SD card back in. The
manual you linked to says that the settings are stored in EEPROM, so they
should be remembered when you switch back to Fedora.
