Failure to bind to port usually always means what the error message say:

[00:03:10] [Server thread/WARN]: The exception was: io.netty.channel.unix.Errors$NativeIoException: bind(…) failed: Cannot assign requested address
[00:03:10] [Server thread/WARN]: Perhaps a server is already running on that port?

Some service or server software is allready using that port. Use the information here https://www.cyberciti.biz/faq/what-process-has-open-linux-port/ to check what is running on that port.

This tells me you have the 10.0.0.101 value in the server.properties field.

In almost 99% of cases, you do not want to fill out this field to match the IP address of the machine. Instead, leave it empty, so it listens on “all” interfaces, 0.0.0.0.

Of course,

This suggests you may also/alternatively have a server actually running a server, but since you’re saying it happens in your fresh install, etc. etc., I’d say you should clear out that server-ip field and try it again.

thanks! got it. so do i just port forward and my buddies should be able to join with my public ip???

Yep, port-forwarding is all you should need to do at this point.
