=== "Linux users"
For reasons that are not entirely clear, installing the correct version of Python can be a bit of a challenge on Ubuntu, Linux Mint, and otherUbuntu-derived distributions.
For reasons that are not entirely clear, installing the correct version of Python can be a bit of a challenge on Ubuntu, Linux Mint, Pop!_OS, and other Debian-derived distributions.
In particular, Ubuntu version 20.04 LTS comes with an old version of Python, does not come with the PIP package manager installed, and to make matters worse, the `python` command points to Python2, not Python3.
On Ubuntu 22.04 and higher, run the following:
Here is the quick recipe for bringing your system up to date:
```
sudo apt update
sudo apt install -y python3 python3-pip python3-venv
sudo update-alternatives --install /usr/local/bin/python python /usr/bin/python3.10 3
```
```
sudo apt update
sudo apt install python3.9
sudo apt install python3-pip
cd /usr/bin
sudo ln -sf python3.9 python3
sudo ln -sf python3 python
```
On Ubuntu 20.04, the process is slightly different:
You can still access older versions of Python by calling `python2`, `python3.8`,
etc.
```
sudo apt update
sudo apt install -y software-properties-common
sudo add-apt-repository -y ppa:deadsnakes/ppa
sudo apt install python3.10 python3-pip python3.10-venv
sudo update-alternatives --install /usr/local/bin/python python /usr/bin/python3.10 3
```
Both `python` and `python3` commands are now pointing at Python3.10. You can still access older versions of Python by calling `python2`, `python3.8`, etc.
Linux systems require a couple of additional graphics libraries to be installed for proper functioning of `python3-opencv`. Please run the following:
`sudo apt update && sudo apt install -y libglib2.0-0 libgl1-mesa-glx`
3. The source installer is distributed in ZIP files. Go to the
