I see you're using Ubuntu, not Raspberry Pi OS. However I have seen a similar issue when installing motion on Raspberry Pi OS. I think I had to create the directory and set ownership manually to get it to work.
Code:
sudo mkdir /var/log/motionsudo chown motion:motion /var/log/motionsudo systemctl start motion.service
