Re: GPSD not running under LINUX Mint 21.1

Perhaps the output of "sudo lsof -i :2947" would help?

I'm no expert, but on Ubuntu that gives:

COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
systemd    1 root  271u  IPv6  45144      0t0  TCP ip6-localhost:gpsd (LISTEN)
systemd    1 root  272u  IPv4  40283      0t0  TCP localhost:gpsd (LISTEN)
gpsd    2704 gpsd    4u  IPv6  45144      0t0  TCP ip6-localhost:gpsd (LISTEN)
gpsd    2704 gpsd    5u  IPv4  40283      0t0  TCP localhost:gpsd (LISTEN)

confirming that gpsd has use of that socket.

Trying to use any software that needs GPSD to read the NEMA data won't work, and I cannot get GPSD to start up. Starting GPSD with either ~$gpsd or ~$sudo gpsd both yield the error "gpsd:ERROR: can't run with neither control socket nor devices". Starting GPSD with sudo gpsd -D 5 -nN /dev/ttyATM0, gives the following output:
gpsd:INFO: launching (Version 3.22)
gpsd:IO: opening IPv4 socket

gpsd:ERROR: can't bind to IPv6 port gpsd, Address already in use
gpsd:ERROR: maybe gpsd is already running!
gpsd:ERROR: command sockets creation failed, netlib errors -1, -1

I've check processes and GPSD isn't running either. Has anyone have an idea as to why this isn't working?

I'm running with Kernel: 5.15.0-67-generic x86_64 bits at this time.
