openjdk-8 установлен неправильно
Я случайно установил openjdk-9-jre-headless, когда я действительно хотел openjdk-8-jre-headless, используя
sudo apt install openjdk-9-jre-headless
Когда я понял это, я сделал
sudo apt remove --purge openjdk-9-jre-headless
sudo apt install openjdk-8-jre-headless
Теперь у меня здесь странная ситуация: [ 119]
~$ java --version
The program 'java' can be found in the following packages:
* default-jre
* gcj-5-jre-headless
* openjdk-8-jre-headless
* gcj-4.8-jre-headless
* gcj-4.9-jre-headless
* openjdk-9-jre-headless
Try: sudo apt install <selected package>
Но:
~$ sudo apt install openjdk-8-jre-headless

openjdk-8-jre-headless is already the newest version (8u131-b11-2ubuntu1.16.04.3).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Что мне здесь делать?

Я уже пробовал

Хорошо, я понял это:
sudo apt remove --purge openjdk-8-jre-headless
sudo apt autoremove
sudo apt install --reinstall openjdk-8-jre-headless
Теперь я получаю как ожидалось
~$ java -version
openjdk version "1.8.0_131"
OpenJDK Runtime Environment (build 1.8.0_131-8u131-b11-2ubuntu1.16.04.3-b11)
OpenJDK 64-Bit Server VM (build 25.131-b11, mixed mode)

ОП решил это, сначала удалив java8, а затем переустановил. Тем не менее, это не всегда выполнимо, если у вас уже есть java-зависимости, например, работающий сервер apache или некоторые другие вещи требуют времени выполнения java. В этом случае сначала удалите java9, затем выполните следующее, непосредственно запустив update-alternatives:
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/java-1.8.0-openjdk-amd64/bin/java" 1
измените путь к java8, если необходимо.
