Dear Maintainer,

   * What led up to the situation?

I was trying all pip3 subcommands.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

$ pip3 debug
Traceback (most recent call last):
  File "/usr/bin/pip3", line 11, in <module>
    load_entry_point('pip==20.0.2', 'console_scripts', 'pip3')()
