Uninstall default-jdk
4
I'm on a fresh Ubuntu 18.04 install. I did a sudo apt-get install default-jdk. Result:
java --version
openjdk 10.0.2 2018-07-17
OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.1)
OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.1, mixed mode)
Now I did sudo apt-get purge default-jdk. Result:
java --version
openjdk 10.0.2 2018-07-17
OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.1)
OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.1, mixed mode)
Why is OpenJDK still there?
apt uninstall openjdk

default-jdk in 18.04 has the following description:
Description: Standard Java or Java compatible Development Kit
This dependency package points to the Java runtime, or Java compatible
development kit recommended for this architecture, which is
openjdk-11-jdk for amd64.
The results of apt-cache depends default-jdk are as follows:
default-jdk
Depends: default-jre
Depends: default-jdk-headless
Depends: openjdk-11-jdk
The results of apt-cache rdepends default-jdk show that openjdk-11-jdk does not depend on default-jdk. default-jdk points to a Java runtime or Java compatible development kit, but uninstalling default-jdk does not uninstall either of these packages.
To remove the packages installed by default-jdk, run the following command:
sudo apt remove openjdk-11-jre-headless openjdk-11-jre openjdk-11-jdk-headless openjdk-11-jdk

Aftersudo apt-get install default-jdkI useapt list --installed | grep openjto see that the packages openjdk-11-jre-headless, openjdk-11-jre, openjdk-11-jdk-headless and openjdk-11-jdk are installed. I useapt list --installed | grep openjagain after asudo apt-get purge default-jdkto see that all 4 packages are still there. Aftersudo apt-get autoremovethe 2 jdk packages are gone but the 2 jre packages are still there!

oh I should add that in the meantime I have done asudo apt-get install openjdk-8-jdk(which has solved my actual problem which I haven't described). So maybe that's the reason why he keeps the jre11 packages despite an autoremove? Which would be weird because why would OpenJDK8 want to have those packages. Anyway, now I have both, default-jdk and openjdk-8-jdk. I switch between the two viasudo update-java-alternatives.
