core-daemon not running #656

Hello,

I'm installing for the first time CORE in a virtual machine with Ubuntu 20.4.

I executed the following steps:

sudo apt install update
sudo apt upgrade
sudo apt dist-upgrade
git clone https://github.com/coreemu/core.git
cd core
./setup.sh
inv install

Then tried to run core-daemon executing:

sudo systemctl enable core-daemon
sudo systemctl start core-daemon
core-daemon

The problem is that it shows an error indicating that the port is already used.

Error - core-daemon:cored - error starting main server on: localhost 4038
OSError: [Errno 98] Address already in use.

But if I run the core-gui-legacy, it opens the legacy gui and in terminal it shows that core-daemon was connected.

I was hoping someone could help me figuring out what's wrong with current the gui or if I'm installing something incorrectly.

Thank you!

If you are already running the service, then that starts core-daemon, so you would not need to do 3 and run core-daemon again. So that makes sense that it would complain about the port already being used.

Since you are running the service and the core-daemon is already running, then the GUI can connect. So it all sounds about right.

Got it! It makes sense.

I'm starting to learn how to use this tool. How would I know that the gui is working?
I'm linking two routers. If I hit run, the legacy version shows a red rectangle turning green for each item and enables the two node tool. Using the current gui, the only thing that changes is the Run button to Stop. The two node tool doesn't appear.

Thanks for your help!

The new GUI would not turn to a stop icon and present an error about the failure to start. So turning to stop without an error, is a good outcome.

Hey, I am also new and have followed the same installation guide. Everything is fine.
However, after running the season in GUI, when I try to ping a address, the run command hangs. Also, the run window looks different than the GUI I found on some youtube tutorials.
Is there any suggestions?
Thanks in advance.

Hello,

I was currently trying to install CORE on my virtual ubuntu version 20.04.5.

I have executed the following command:

git clone https://github.com/coreemu/core.git
cd core
./setup.sh
inv install

I am getting the following error:

installing core virtual environment ... |Encountered a bad command exit code!

Command: 'cd daemon && poetry install --no-dev'

Exit code: 1

Stdout:

1184│
1185│ return decode(output)
1186│
1187│ def execute(self, bin, *args, **kwargs):

Stderr:

Can anyone suggest to me what I should do?

This will happen usually related to trying to build a python dependency from source, and you are missing system packages to build it.

You can run the command given manually to see the specific error, or run the install again with the -v to see all output

@bharnden Thank you for your quick response. After running the install again with -v the output us like:
