Thanks for the hint. I installed scilab from scratch like this: sudo apt install -t bionic-proposed scilab
To make sure that all packages comes from -proposed. Now when it is called from its graphical launcher, it flashes for a second then closes. It runs when it is called from the terminal. http://bugzilla.scilab.org/show_bug.cgi?id=14682 ** Bug watch added: Scilab bugtracker #14682 http://bugzilla.scilab.org/show_bug.cgi?id=14682 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1807602 Title: Scilab does not start on disco and bionic-proposed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/scilab/+bug/1807602/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
