Please run scilab with full debugging enabled and paste (or attach) the full output in this bug. In order to do so, run the following command in a terminal:
$ bash -x /usr/bin/scilab Also, I noticed that your original report mentioned that you linked default-java to java-8-oracle. This should not be necessary as you have default-jre-headless installed and it should have created the /usr/lib/jvm/default-java by itself. So please check that /usr/lib/jvm /default-java is correctly linked to openjdk-11 directory - if it is not, please remove the manually created link and reinstall the default- jre-headless package. $ ls -l /usr/lib/jvm/default-java /usr/lib/jvm/default-java -> java-1.11.0-openjdk-amd64 And it should belong to default-jre-headless: $ dpkg -S /usr/lib/jvm/default-java default-jre-headless: /usr/lib/jvm/default-java -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1834265 Title: scilab fails to start missing java-8-oracle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/scilab/+bug/1834265/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
