How to Install Python 3.12 on Ubuntu 22.04

-
python 3.12 installation

Ubuntu 22.04 ships with Python 3.10 by default. Since I needed Python 3.12 for newer features and compatibility, I installed it manually. Here’s how I safely set it up alongside the system Python.

Step 1: Update your system

sudo apt update
sudo apt upgrade -y

Step 2: Install Python 3.12 and tools

sudo apt install -y python3.12 python3.12-venv python3.12-setuptools python3.12-dev
  • python3.12: The main Python 3.12 interpreter.
  • python3.12-venv: Enables creation of virtual environments using python3.12 -m venv.
  • python3.12-setuptools: Provides tools to build and install Python packages (replacement for deprecated distutils).
  • python3.12-dev: Includes headers and libraries needed to build Python C extensions and compile native modules.

Step 3: Set python3 to point to Python 3.12

If your system still points to an older version, you can use update-alternatives to switch. 

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.12 2
sudo update-alternatives --config python3

You will see a prompt like this:

There are 2 choices for the alternative python3 (providing /usr/bin/python3).

  Selection    Path                Priority   Status
------------------------------------------------------------
* 0            /usr/bin/python3.12   2        auto mode
  1            /usr/bin/python3.10   1        manual mode
  2            /usr/bin/python3.12   2        manual mode

Press <enter> to keep the current choice[*], or type selection number: 2

Step 4 (Optional): Set the python command to point to Python 3.12

sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.12 2
sudo update-alternatives --config python

You will see a prompt like this:

There is 1 choice for the alternative python (providing /usr/bin/python).

  Selection    Path                Priority   Status
------------------------------------------------------------
* 0            /usr/bin/python3.12   2        auto mode
  1            /usr/bin/python3.10   1        manual mode
  2            /usr/bin/python3.12   2        manual mode

Press <enter> to keep the current choice[*], or type selection number: 2


Step 5: Verify your Python versions

python3 --version
Python 3.12.3

python --version
Python 3.12.3
Location: Calgary, AB, Canada

How to Set Up Vaultwarden (Bitwarden) on Synology NAS (Best Free Alternative to LastPass)

-
Image
Have you ever felt overwhelmed managing passwords for all your websites? I used to use the same password across multiple sites , which wasn’t secure. To manage them better, I started using LastPass for years. However, in 2019, they changed their pricing policy — now it’s free only for one device for 30 days, and you have to pay to use it across multiple devices . If you're looking for a powerful and free password manager, Vaultwarden is one of the best alternatives to LastPass. What is Vaultwarden? Vaultwarden (formerly known as Bitwarden_RS) is a lightweight, open-source implementation of the Bitwarden server API written in Rust . It is fully compatible with official Bitwarden clients and is ideal for low-resource environments. Example: On a Synology DS916+, Vaultwarden uses 0% CPU and only 64MB of memory while running. My Setup NAS Model : Synology DS916+ DSM Version : DSM 7.1-42661 Update 1 Docker Image : vaultwarden/server Ins...
