Arduino Port Not detected and can not run it as root

Question

I have two Ubuntu one is 18.04 and another is 20.04, also i have some problem with Arduino boards,i have tried this instruction(pin connections and ...):

But, the Arduino IDE can not detect the STM32f013c8t6 board with Arduino, so i tried to find the USB connection of the port by using this post commands of its answers, as you can see below:

sudo usermod -a -G dialout $USER
 ls -al /dev/USB*
ls: cannot access '/dev/USB*': No such file or directory

And by trying some others post instructions :


lsusb

Bus 001 Device 005: ID 0bda:0821 Realtek Semiconductor Corp.

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

and by trign the lsb -v -d command i get the below result:

so can not see the port connection on the Arduino which has been installed by snap as you can see below :

Also, tried to run Arduino as root user but i get below error:

sudo arduino

So i guess this is not working because of installing the Arduino by snap and trued to fix it by sudo snap connect arduino:removable-media command but i get the mkdir: cannot create directory '/run/user/0': Permission denied error again, so i asked here:

Update1:

Based of the first comment i tried the sudo journalctl -fand get the below results:

sudo journalctl -f

Also i have installed the last Arduino version by this link and is is running by sudo arduino command but is til have this problem!.

Update2:

It is strange i have seen the below post which is saying the ST-link V2 programmer could be fake and have some wrong pin connection, and if possible i like to ask, what would be happening if i change the 2,4,6 pins configuration based of that post? as you can see below:

Update 3:

I have checked the ST-Link V2 and the pins was labeled correctly. so the problem is not from the wrong st-link pins system!. Thanks.

Your guesses are wrong. usermod changes system files that are only consulted at login. — waltinator, Jun 13 '21 at 15:44
Your guesses are wrong. Watch sudo journalctl -f as you connect the Arduino. It's probably /dev/ttyUSB*. — waltinator, Jun 13 '21 at 15:47
ST-LInk may not be recognized as ttyUSB and it is normal. You have to find specific guide for setting up ST-Link on Ubuntu. As starting point you can use this document. For more reproducible results please install Arduino IDE using ubuntu-make and remove snap version (if any). — N0rbert, Jun 13 '21 at 16:17

Based ofN0rbert Comment,The problem exist by snap version of Arduino which is said here:

So I have done the below step:

1- I have installed the last Arduino version by this link.

2-Based of this document, I have installed the STM32CubePrg

3-Selecting the below setting and codes for test :

#define LED_BUILTIN PC13
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(2000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}

4- Switch the BOOT 0 header from the '0' position to the '1' position before connecting the FTDI board to the computer for flashing the bootloader as said on this video from this post:

Thank.
