Thanks for reporting. >From the package publishing history it looks like it was removed because the package hadn't been ported to QT5, see https://launchpad.net/ubuntu/+source/scidavis/+publishinghistory or https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=894581 for more details. (Looks like it was first removed from Debian, and then Ubuntu followed).
So it looks like a QT5-version of scidavis could be readded to the current development version of Ubuntu, and perhaps from there backported to 18.04. ** Bug watch added: Debian Bug tracker #894581 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=894581 ** Package changed: ubuntu => scidavis (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1769303 Title: scidavis package not in bionic repository To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/scidavis/+bug/1769303/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
