Java 11 to 8: update-alternatives: error: no alternatives for mozilla-javaplugin.so












0















I have Java 11 and 8 in my Ubuntu 18.04, side by side.
I mean to set Java 8 as the default.



What I get:



$ sudo update-java-alternatives --set /usr/lib/jvm/java-1.8.0-openjdk-amd64
update-alternatives: error: no alternatives for mozilla-javaplugin.so
update-java-alternatives: plugin alternative does not exist: /usr/lib/jvm/java-8-openjdk-amd64/lib/IcedTeaPlugin.so


How can I fix this?



I am not sure if using (see this)



sudo update-java-alternative —jre-headless -s java-1.8.0-openjdk-amd64


is ok.



This is the opposite change from



update-alternatives: error: no alternatives for mozilla-javaplugin.so
