Je ne parviens pas à installer JRE et JDK sur Ubuntu 18.04 LTS

Je ne peux pas installer à la fois le JRE et le JDK. Tout d'abord, je n'ai pas essayé d'installer le JDK, mais je suppose que si je le faisais, cela ne fonctionnerait pas car vous devez installer le JRE.

Deuxièmement, je ne peux pas installer JRE, j'ai suivi beaucoup de tutoriels tels que https://www.lifewire.com/install-Java-on-ubuntu-4125508 , et le Java et javac les commandes ne fonctionnent pas. Il dit: Command 'Java' not found, but can be installed with: ... et je ne suis pas sûr de ce que openjdk est. Aidez-moi, s'il vous plaît.

P.S. J'ai aussi cherché des questions sur Ask Ubuntu, mais aucune d'entre elles n'a été utile.

P.P.S. Voici le journal:

modifier/P.S. Pour ceux qui pensent qu'il s'agit d'un doublon, vous vous trompez. Je n'utilise pas de machine virtuelle, j'ai essayé et essayé encore jusqu'à ce qu'elle réussisse, et elle l'a fait. Mon problème est que le JDK n’a pas été installé. Je l'ai découvert lors de l'installation de NetBeans et aucun JDK n'était installé, mais le JRE était installé.

JDK inclut JRE avec, vous n'avez donc besoin que de JDK pour les deux.

Votre session de terminal indique que le téléchargement du programme d’installation du JDK Oracle Java 8 a été corrompu (sha256sum mismatch jdk-8u171-linux-x64.tar.gz). Pour résoudre le problème et installer à nouveau:

Sudo rm /var/cache/Oracle-jdk8-installer/*.tar.gz
Sudo apt-get update
Sudo apt-get install --reinstall Oracle-Java8-installer

Si vous installez jdk, vous n'avez pas besoin d'installer jre.

Qu'est-ce qui se passe si vous faites juste

Sudo apt-get install default-jdk
