Eu queria instalar o Temurin JDK 8 e 11, instalei-os seguindo estas etapas
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
Mas não tenho certeza se isso está 100% certo e como faço para gerar o arquivo .jinfo, isso é necessário?

Você pode usar oRepositório Adoptium Debian/Ubuntu
Adicione a chave GPG do Eclipse Adoptium
wget -O - https://packages.adoptium.net/artifactory/api/gpg/key/public | sudo apt-key add -
Adicione o repositório apt 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
Instale a versão do Temurin que você precisa
sudo apt update # update if you haven't already sudo apt install temurin-8-jdk sudo apt install temurin-17-jdk
Configurar a versão padrão
sudo update-alternatives --config java

Extraí o script do pacote deb AdoptOpenJDK original e da versão modificada 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
