It appears that ROS is currently installed. Each ROS release is very strict about the versions of Ubuntu it supports, and Ubuntu upgrades can fail if that guidance isn't followed. Before continuing, please either uninstall ROS, or ensure the ROS release you have installed supports the version of Ubuntu to which you're upgrading.

For ROS 1 releases, refer to REP 3:

For ROS 2 releases, refer to REP 2000:
