This looks like as if the webinterfaces or Moonraker have not been installed properly.
Try repeating their installation. My advice would be using KIAUH.

3

I did do a reinstall. I’ll try again.

4

reinstalled a second time and same result.

5

Log in via SSH and post the output of

ls -al ~/printer_data/logs/

If you use a recent KIAUH, make sure not to use the v6 alpha version. In the dialog at KIAUH’s start say “No” (2) when asked for it.

6

reinstalled using option 2, and same result.
Here are the other results

Did you even install Klipper via KIAUH?

What does happen when you issue the command:

sudo service klipper restart
8

yes I used KIAHU. I issued the command. Same result.

This is strange. Somehow your installation seems messed up, which can be a pain to diagnose remote.
I suggest to start over:

  • Use a server version for your host. The desktop versions often do things that interfere with Klipper
  • Follow Installing Klipper with KIAUH to install Klipper. Do not use the v6 alpha version.
10

how do i use a server version?

11

https://ubuntu.com/download/server

12

OK. I thought you meant a server version of Klipper.

13

So I tried the server version,but it was too over my head. So i reinstalled Ubuntu and now I have this for my logs.

moonraker.log (132.2 KB)

This

[mcu]
serial: /dev/serial/by-id usb-1a86_USB_Serial-if00-port0

cannot be correct.
Refer to Installing Klipper with KIAUH and in particular chapter 5

potentially I could be

serial: /dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0

Note that Desktop versions introduce additional points of failure. So be sure to check OS Sanity Checks and Fixes

Finally worked. Thanks for your help.
