I'd reported a similar problem at Bug #1637781. I uninstalled all ros- indigo packages while leaving ros-jade installed, but still got "Could not calculate the upgrade" when attempting to upgrade 14.04 LTS to 16.04 LTS.
So this may be a problem with ros-jade as well as the older ros-indigo. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1611737 Title: Can't upgrade from 14.04 to 16.04 if ros-indigo-desktop-full or ros- indigo-perception installed from ROS servers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1611737/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
