[BUG] Error: couldn't open socket: connection refused

[maxalonsox]

When I open core, core-daemon doesn't work

max@max-pc:~$ core-gui
Connecting to "core-daemon" (127.0.0.1:4038)...
This feature requires a connection to the CORE daemon.

Failed to connect to 127.0.0.1:4038!

Have you started the CORE daemon with '/etc/init.d/core-daemon start'?
  (Error: couldn't open socket: connection refused)

I try with

max@max-pc:~$ /etc/init.d/core-daemon start
starting core-daemon
/etc/init.d/core-daemon: 41: cannot create /var/run/core-daemon.pid: Permission denied
/etc/init.d/core-daemon: 38: cannot create /var/log/core-daemon.log: Permission denied
unable to start core-daemon, see /var/log/core-daemon.log

It tells me that I have permissions denied, so

max@max-pc:~$ sudo /etc/init.d/core-daemon start
starting core-daemon

It seems to work, but when I open core, again...

max@max-pc:~$ sudo core-gui
Connecting to "core-daemon" (127.0.0.1:4038)...
This feature requires a connection to the CORE daemon.

Have you started the CORE daemon with '/etc/init.d/core-daemon start'?
  (Error: couldn't open socket: connection refused)

(The gui still works but when using something I need the daemon for a popup comes up informing me of this)

And if I try with sudo core-daemon...

max@max-pc:~$ sudo core-daemon
Traceback (most recent call last):
  File "/usr/local/bin/core-daemon", line 16, in <module>
    from core import constants
ModuleNotFoundError: No module named 'core'

Desktop :

• OS: Ubuntu 20.04.4 LTS
• CORE Version 6.3.0
• EMANE Version 1.5.1

Version is too old to really provide current support for, but there is a disconnect for however you installed CORE.
