I’ve been running OctoPi but don’t have a camera to run Octolapse. Fortunately, I have an unused Amazon Deeplens as an alternative. Deeplens runs on Ubuntu 16, and is more powerful than a RaspberryPi. So, running OctoPrint is a matter of installing some packages. Whole process should take less than half an hour.
Here are steps to run OctoPrint on Amazon Deeplens.
If you don’t have a power supply. Then purchase an 5V-4A power supply.

Detailed Instructions:
Set up OctoPrint on port 8080:

root@Deepcam:/home/aws_cam# apt install python3.7
root@Deepcam:/home/aws_cam# apt-get install python3.7-venv -y
root@Deepcam:/home/aws_cam/OctoPrint# apt install python3.7-dev
aws_cam@Deepcam:~$ mkdir OctoPrint && cd OctoPrint
aws_cam@Deepcam:~/OctoPrint$ python3.7 -m venv venv
aws_cam@Deepcam:~/OctoPrint$ source venv/bin/activate
(venv) aws_cam@Deepcam:~/OctoPrint$ pip install pip --upgrade
(venv) aws_cam@Deepcam:~/OctoPrint$ pip install octoprint
(venv) aws_cam@Deepcam:~/OctoPrint$ sudo usermod -a -G tty aws_cam
(venv) aws_cam@Deepcam:~/OctoPrint$ sudo usermod -a -G dialout aws_cam
aws_cam@Deepcam:~$ sudo ufw allow 8080
(venv) aws_cam@Deepcam:~/OctoPrint$ ~/OctoPrint/venv/bin/octoprint serve --port 8080
Set up OctoPrint to auto start on boot
aws_cam@Deepcam:~$ wget https://github.com/OctoPrint/OctoPrint/raw/master/scripts/octoprint.service && sudo mv octoprint.service /etc/systemd/system/octoprint.service
aws_cam@Deepcam:~$ sudo vi /etc/systemd/system/octoprint.service
