For developers who want to prepare their project for the latest Python releases, here’s how to install the current Python 3.15 pre-release in all current Ubuntu releases.<\/p>\n

Python 3.15 is so far in the development stage, which features explicit lazy imports for faster startup times, frozendict<\/code> and sentinel<\/code> built-in types, a dedicated profiling package for organizing Python profiling tools, new PyBytesWriter<\/code> C API to create a Python bytes object, and more. See the what’s new<\/a> page for details.<\/p>\n

How to Install Python 3.15 (Pre-release So far)<\/h3>\n

Python is easy to install in Ubuntu by either using the popular Deadsnakes PPA or building from the source. Choose either one that you prefer.<\/p>\n

Option 1: Install Python 3.15 from PPA<\/h4>\n

For Ubuntu 22.04, Ubuntu 24.04, Ubuntu 26.04 and their derivatives such as Linux Mint 21\/22, the Deadsnakes PPA<\/a> has made the packages for all supported CPU architecture types: amd64, arm64\/armhf, ppc64el, and s390x.<\/p>\n

1.<\/b> First, press Ctrl+Alt+T<\/b> on keyboard to open terminal. Then paste the command below and hit run to add PPA:<\/p>\n

sudo add-apt-repository ppa:deadsnakes\/ppa<\/pre>\n
Type user password (no asterisk feedback) when it asks and hit Enter to continue.<\/i><\/p>\n
\"\"
\n2.<\/b> Then refresh package cache. It should be done automatically during adding PPA, though Linux Mint user may need to do this job manually by running command:<\/p>\n
sudo apt update<\/pre>\n
3.<\/b> Finally, run command to install Python 3.15:<\/p>\n
sudo apt install python3.15-full<\/pre>\n
As you see in the screenshot, this command will install Python 3.15 as well as the dbm database, Tk applications, and pyvenv binary support.<\/p>\n
You may also install idle-python3.15<\/code> package for the default IDE using Tkinter, or replace python3.15-full<\/code> with python3.15<\/code> for the minimal install.<\/p>\n
\"\"<\/p>\n
Option 2: Compile and install Python 3.15 from source<\/h4>\n
Don’t trust third-party repositories or you’re running Ubuntu 20.04 or Ubuntu 18.04 that PPA does not support? It’s easy to build Python from the source tarball.<\/p>\n
1.<\/b> First download the source tarball from its ftp download page:<\/p>\n
\n
Python FTP Download Page<\/a><\/div>\n<\/div>\n
2.<\/b> Then open ‘Downloads’ folder, extract the source tarball, finally right-click on source folder and select “Open in Terminal”.<\/p>\n
\"\"<\/p>\n
3.<\/b> When terminal opens, run the command below to install the dependency libraries for building the source:<\/p>\n
sudo apt install wget build-essential libreadline-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev libffi-dev zlib1g-dev<\/pre>\n
Then, run commands below one by one to configure and build Python:<\/p>\n
.\/configure --enable-optimizations<\/pre>\n
sudo make -j8 && sudo make altinstall<\/pre>\n
Verify:<\/h3>\n
Once installed Python 3.15, verify by running command:<\/p>\n
python3.15 --version && pip3.15 --version<\/pre>\n
Set Python 3.15 as default (for PPA package)<\/h3>\n
NOTE: If you built Python 3.15 from source via the steps above, then it should be already set as default. Try running python3 --verison<\/code> to verify!<\/b><\/p>\n
It’s NOT recommended to set non-preinstalled Python package as default for Python3, because it may break some applications.<\/p>\n
If you insist, try to set python3.15<\/code> as default by running the commands below one by one:<\/p>\n
