rosdep install broken

[ValerioMagnago]

It was not possible to resolve automatically the ros dependencies by running:

λ › rosdep install --from-path ./src --ignore-src                                 
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
vesc_driver: Cannot locate rosdep definition for [serial]

Ros is not able to solve the serial dependency

λ › rosdep resolve serial
ERROR: no rosdep rule for 'serial'

but ros-noetic-serial is a valid ROS package and can be installed via apt.
