Please file a bug report with your upstream.  Help your distro not
confuse any more poor users.

This would have been spotted right away if you had sent us the output
of gpsdebugingo run as root.  Get a copy here:

https://gpsd.io/gpsdebuginfo

Please do that next.  That will save a lot of back and forth asking you
what versions of things you have, etc.

How did you install gpsd?  That is NOT part of the default gpsd install!
I assume you got a package from somewhere?  Somewhere that is not us?

Sudo?  Sudon't"

We hope.

Ambitious to start with, but looks OK.

Those line numnbners don't work for me/  Are you using a really old gpsfake?

> Does this error mean anything to you?

Yeah, it looks like you are using a Python2 program under Python3....

Can you try the lates gpsd release (3.24) or gsd from git?
You already showed you package has problems, this looks like anouther one.
