Hi I have a new installation of Hugo using snap install and when I try to do Hugo server, it gives me an error saying  
port 1313 already in use, attempting to use an available port  
panic: runtime error: invalid memory address or nil pointer dereference  
[signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x12f0db7]

While I tried looking into similar posts in the same forum, those solutions did not help.

The difficulty here is that it does not go and take a new available port … instead, it gives this huge error.

Can you help?

It used to work nicely when I had Hugo 55. Now that I have updated to Hugo 58, I am getting this error.

hi,

this happens if you start **hugo server** twice.

I can’t help with @prabhakar_shanmugam’s question, but want to let you all know that I have no problem running `hugo server` twice on Windows using hugo v0.58.3. I just tested it and here’s an excerpt from the second instance of `hugo server`:

```auto
port 1313 already in use, attempting to use an available port
Building sites …
 : 
 :  
Web Server is available at //localhost:63987/ (bind address 127.0.0.1)
Press Ctrl+C to stop

```

Good luck debugging this!

Hi

Thanks for the reply.

I restarted the system to be sure if thats not the case.

In a fresh restart and a fresh terminal i tried and I still get the same.

How to ascertain this and how to delete / kill the other hugo instance.

On a second thought, could it be because I installed Hugo using snapcraft.

Thanks again

Hi

I uninstalled hugo that i installed through snap  
I reinstalled using the deb file download from github  
It workssss!!!

I thank you again for your time.

May be its the snap install that made it corrupt. I am not sure.
