* python 3.9 설치

# add-apt-repository ppa:deadsnakes/ppa

# apt update

# apt install wget software-properties-common

# apt install python3.9

4.) (NOT Recommended) To use Python 3.9 as the default python3, run commands:

 

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 1

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.9 2

 

* ppa 관련 에러가 나타날 경우 해당 ppa 제거

sudo add-apt-repository --remove ppa:webupd8team/ppa

sudo apt update

Ubuntu 19.04 Error 404 Not Found [IP: 91.189.95.83 80] error on apt update

 

For Ubuntu 16.04 and Ubuntu 18.04, replace python3.8 in the code with system’s default python3 version..
And you can then switch between the two Python3 versions via command:

 

sudo update-alternatives --config python3

 

NOTE: Due to known bug, terminal won’t open if you changed python3 symlink. An workaround is recreate a symlink via command (Replace python 3.8 with your system default python3 version):sudo rm /usr/bin/python3; sudo ln -s python3.8 /usr/bin/python3Uninstall:

To uninstall the Python3.9 packages, run command:

sudo apt remove --autoremove python3.9 python3.9-minimal

Installing Python 3.9 Using Source Code

You also have one more option option to install Python 3.9 using source code. We don’t recommend to install Python 3.9 packages from source code. But in some cases you may need to install Python from source code.

So follow the below instructions to install Python 3.9 using source code on Ubuntu 20.04 Linux system.

1. First of all, install essential packages for compiling source code. Open a terminal and execute following commands:
2.  
3. sudo apt install build-essential checkinstall
4. sudo apt install libreadline-gplv2-dev libncursesw5-dev libssl-dev \ libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev libffi-dev zlib1g-dev
5. Now, download the Python 3.9 source code from official download site. Switch to a relevant directory and use wget to download source file.
6. cd /opt
7. sudo wget https://www.python.org/ftp/python/3.9.0/Python-3.9.0.tgz
8. Next, extract the downloaded archive file and prepare the source for the installation.
9. tar xzf Python-3.9.0.tgz
10. cd Python-3.9.0
11. sudo ./configure --enable-optimizations
12. Python source is ready to install. Execute make altinstall command to install Python 3.9 on your system.
13. sudo make altinstall

    make altinstall is used to prevent replacing the default python binary file /usr/bin/python.

14. The Python 3.9 has been installed on Ubuntu 18.04 system. Verify the installed version:
15. python3.9 -V
16. Python 3.9.0
17. Remove the downloaded archive to free space
18. sudo rm -f /opt/Python-3.9.0.tgz

Conclusion

In this tutorial, you have learned to install Python 3.9 on Ubuntu 20.04 using Apt and source code. You can try Python examples via command line.
