I would like to add that the proposed workaround to downgrade the openjfx packages is NOT a solution because no security updates will be available. The correct solution is to provide an openjfx-8 package as proposed by the TO or to roll back the openjfx package to version 8. The current openjfx package breaks the openjdk-8 package for Java FX applications and is unnecessary because openjfx-11 is a jar only solution that does not require package management by Ubuntu but can be fetched via maven or alike.
While this is not fixed, the packages have to be put on hold for updates sudo apt install \ openjfx=8u161-b12-1ubuntu2 \ libopenjfx-java=8u161-b12-1ubuntu2 \ libopenjfx-jni=8u161-b12-1ubuntu2 sudo apt-mark hold \ openjfx \ libopenjfx-java \ libopenjfx-jni -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799946 Title: OpenJFX-11 does not work with OpenJDK-8 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjfx/+bug/1799946/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
