Ubunto python 3.10 to python3.12 설치

 

Ubunto python 3.10  upgrade  to python3.12 

 - 파이썬의 업그레이드와 이전 버전의 파이썬 삭제하여 정리하는 방법을 정리 합니다.

 

Step 1: Update CA Certificates

sudo apt update 
sudo apt install --reinstall ca-certificates -y 
sudo update-ca-certificates

 

 

Step 2 :  PPA (Personal Package Archive)  Repository

$ sudo apt update && sudo apt upgrade -y
$ sudo apt install software-properties-common -y
$ sudo add-apt-repository ppa:deadsnakes/ppa

 

 

Step 3: Use Manual Source Instead of

# use apt-repository install with apt

sudo apt update 
sudo apt install python3.12 -y


or

# Step 3: Use Manual Source Instead of add-apt-repository

# 1.Create a new .list file:
echo "deb http://ppa.launchpad.net/deadsnakes/ppa/ubuntu $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/deadsnakes-ppa.list

# 2. Import the GPG key:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6A755776



# installation with source
wget https://www.python.org/ftp/python/3.12.0/Python-3.12.0.tgz
tar -xvf Python-3.12.0.tgz
cd Python-3.12.0
./configure
make
sudo make install

 

 

Step 4:   apt install python3.12 -y

sudo apt update sudo apt install python3.12 -y


python3.12 --version

* manual .list + GPG key method step by step (avoiding add-apt-repository

 

 

Step 5:   Optional: Set Python 3.12 as default

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

 

 * /usr/bin/python3.12
   /usr/bin/python3 -> /etc/alternatives/python3
   /etc/alternatives/python3 -> /usr/bin/python3.12*  

 

 

 

Step 6: Clean old packages

sudo apt autoremove -y

* Since apt told you some packages are no longer required : for free space.
