jupyter: the notebook server could not be started because no available

i am trying to start a jupyter notebook on localhost:8888 (the default), but all i get is this:

$ jupyter-notebook --debug

(...repeats...)
[C 23:02:00.987 NotebookApp] ERROR: the notebook server could not be started because no available port could be found.
[D 23:06:42.909 NotebookApp] Exiting application: jupyter-notebook

i tried various different ports, both much lower and much higher, as starting points, and raised the number of retries, but the result is always the same.

it has been suggested to look if jupyter is already running (ps aux|grep jupyter) and check the ports (sudo netstat -tnlp) - but it is not running, and none of the ports seems to be in use.

searching permutations of the error messages does not bring up more.

i feel i am missing something obvious...
