Cómo instalar correctamente Temurin JDK con alternativas de actualización

Quería instalar Temurin JDK tanto 8 como 11, los instalé siguiendo estos pasos

wget https://github.com/adoptium/temurin8-binaries/releases/download/jdk8u312-b07/OpenJDK8U-jdk_x64_linux_hotspot_8u312b07.tar.gz
tar xzf OpenJDK8U-jdk_x64_linux_hotspot_8u312b07.tar.gz

sudo mv jdk8u312-b07/  /usr/lib/jvm/temurinjdk-8-hotspot-amd64

sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/temurinjdk-8-hotspot-amd64/bin/java" 1081
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/temurinjdk-8-hotspot-amd64/bin/javac" 1081

Pero no estoy seguro de si esto es 100% correcto y ¿cómo genero el archivo .jinfo?

Puedes usar elRepositorio Adoptium Debian/Ubuntu

  1. Agregue la clave GPG de Eclipse Adoptium

    wget -O - https://packages.adoptium.net/artifactory/api/gpg/key/public | sudo apt-key add -

  2. Agregue el repositorio apto de Eclipse Adoptium

    echo "deb https://packages.adoptium.net/artifactory/deb $(awk -F= '/^VERSION_CODENAME/{print$2}' /etc/os-release) main" | sudo tee /etc/apt/sources.list.d/adoptium.list

  3. Instale la versión de Temurin que necesite

    sudo apt update # update if you haven't already
sudo apt install temurin-8-jdk
sudo apt install temurin-17-jdk

  4. Configurar la versión predeterminada

    sudo update-alternatives --config java

Extraje el script del paquete deb AdoptOpenJDK original y modifiqué la versión que uso como:

wget https://github.com/adoptium/temurin17-binaries/releases/download/jdk-17.0.1%2B12/OpenJDK17U-jdk_x64_linux_hotspot_17.0.1_12.tar.gz

mkdir -p /usr/lib/jvm

sudo tar -xvvf OpenJDK17U-jdk_x64_linux_hotspot_17.0.1_12.tar.gz -C /usr/lib/jvm/

sudo ./java-alternative install /usr/lib/jvm/jdk-17.0.1+12
sudo ./java-alternative set /usr/lib/jvm/jdk-17.0.1+12
…
sudo ./java-alternative remove /usr/lib/jvm/jdk-17.0.1+12

Código fuente del script:

#!/bin/sh

if [ ! -d "$jdk_base_dir" ]
then
    echo "Invalid java directory. Choose one of: ";
    ls -1d /usr/lib/jvm/*
