Linux - GIGA - Can not open DFU device

Hi,
I setup new release of arduino IDE 2.3.4 on Mint.
GIGA is recognized on /dev/ttyACM1 and I can not access it, IDE can not upload data:

dfu-util: Warning: Invalid DFU suffix signature
dfu-util: A valid DFU suffix will be required in a future dfu-util release
dfu-util 0.10-dev

dfu-util: Cannot open DFU device 2341:0366 found on devnum 15 (LIBUSB_ERROR_ACCESS)
dfu-util: No DFU capable USB device available
Failed uploading: uploading error: exit status 74

this port have full right and I am in the right group (dialout) with access:
crw-rw-rw- 1 root dialout 166, 0 Feb 7 07:28 /dev/ttyACM0
crw-rw-rw- 1 root dialout 166, 1 Feb 7 07:37 /dev/ttyACM1
crw-rw---- 1 root dialout 188, 0 Feb 7 07:49 /dev/ttyUSB0

I do not have access to ACMx but have access to USBx and Arduino Uno.
How to solve it?
Regards

Hi @viayner. In order for Arduino IDE to upload to the Arduino board, your user account must have write permission for that device. Standard user accounts don't have this permission by default. This error can occur when you attempt an upload without the necessary permissions. So it is necessary to configure your system to allow the upload. This is done by creating a special file. Arduino provides a script that will create the file for you.

I'll provide instructions you can follow to run that script:

  1. Open the following URL in your web browser:
    https://github.com/arduino/ArduinoCore-mbed/blob/main/post_install.sh
  2. Click the downward pointing arrow icon ("Download raw file") at the right side of the toolbar:
  3. Wait for the download to finish.
  4. Open a command line terminal in the folder that contains the downloaded file.
  5. Type the following command:1
    chmod +x post_install.sh && sudo ./post_install.sh
    
  6. Press the Enter key.
  7. If prompted for it, enter your Linux account password and press the Enter key.

The command should complete successfully. Now try uploading again, just as you did before. Hopefully the error will no longer occur.

Although outdated, this approach will work for boards like the UNO R3 that are uploaded to via a serial port. However, that is not the case with the GIGA R1 WiFi board. Uploads to the GIGA R1 WiFi are instead done via the DFU (device firmware upgrade) mechanism, and so being in the dialout user group is not sufficient.

well im using wndows 10 and same dfu problem
but warning but it uploads
