Ubuntu/Python/3.14

Install with DeadSnakes PPA

Dependency:

apt update ; sudo apt -y install software-properties-common

Add Deadsnakes and install python 3.14

sudo add-apt-repository ppa:deadsnakes/ppa
  # respond to prompts
  # OR
  yes | sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update

# sudo apt install python3.14
## BETTER, should also install virtual-env
sudo apt -y install python3.14-dev python3.14-venv
## EVEN BETTER, 
sudo apt -y install python3.14-dev python3.14-venv python3.14-full

python3.14 --version

(dup) For development, virtuan env (dup above)

# sudo apt install python3.14-dev python3.14-venv

For a more complete installation including the ensurepip, Tkinter IDE and other utilities, you can use:

sudo apt install python3.14-full

# ensurepip 
python3.14 -m ensurepip --version

Pip 3.14:

# First, try and see if pip responds
sudo python3.14 -m pip --version

If it is happy, try upgrading it:

sudo python3.14 -m pip install --upgrade pip

If it fails to upgrade, or there is an issue, or if Pip was previously installed, but is sad:

sudo apt -y remove python3-pip

## OR try force upgrading it
sudo python3.14 -m pip install --upgrade --ignore-installed pip

If Pip was not previously installed:

## not needed
# mkdir ~/.src ; cd ~/.src
# mkdir pip3.14 ; cd pip3.14

# system wide
curl -sS https://bootstrap.pypa.io/get-pip.py | sudo python3.14

# Ubuntu 26
sudo apt install python3-pip
sudo python3.14 -m pip install --upgrade --ignore-installed --break-system-packages pip

# or user only:
curl -sS https://bootstrap.pypa.io/get-pip.py | python3.14

Verify:

sudo python3.14 -m pip --version
python3.14 -m pip --version

sudo pip3.14 --version
pip3.14 --version

sudo which pip3.14
which pip3.14

Upgrade:

sudo python3.14 -m pip install pip --upgrade
# or
python3.14 -m pip install pip --upgrade

sudo python3.14 -m pip --version
python3.14 -m pip --version

List

python3.14 -m pip list

venv: (requires pip)

python3.14 -m venv -h

# check if pip is working
python3.14 -m ensurepip
  #   /usr/bin/python3.14: No module named ensurepip
  # if this fails with the above, install pip and python3.14-venv ^

cd ~ ; rm -rf .test-venv ; mkdir .test-venv ; cd .test-venv ; python3.14 -m venv venv

Version checks:

pip --version
pip3.14 --version
python3.14 -m pip --version

pip3.14 script

Dead-Snakes doesn't install the pip3.14 script for reasons (as you will see...) You can manually install, by copying the python 3.12 version, and changing the shebang header from python3 to python3.14. Only useful as a convenience for regular users, not for root.

cd /usr/bin
cp pip3.12 pip3.14
sed -i "s/python3/python3.14/" pip3.14

Note, calling pip directly as root will error out, but at least as users you can call it to install local packages

pip3.14 install pip --upgrade
 ERROR: Cannot uninstall pip 24.0, RECORD file not found. Hint: The package was installed by debian.

/usr/bin/pip3.14

#!/usr/bin/python3.14

from pip._internal.cli.main import main
if __name__ == "__main__":
    sys.argv[0] = re.sub(r"(-script\.pyw|\.exe)?$", "", sys.argv[0])
    sys.exit(main())

Alternatively, you could also just create an alias:

alias pip3.14="python3.14 -m pip"
