I had the same error and I solved it. First remove ros using the command: sudo apt-get remove ros-*
If you have created any workspace you have to remove that too. If you have added setup scripts to you .bashrc then remove that too. For that use the command: gedit .bashrc and then remove all the last commands with ros and your workspaces. After doing these steps, use the commands: sudo apt-get clean and sudo apt-get autoclean This will solve the error. -- 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 a release if ros packages are 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
