Thank you. An error occurred while uploading the sketch

Install arduino on Nano pi m4 and asus thinkerboard with os armbian and arduino uno wifi rev2 board connected to USB Arduino allways complains with : avrdude : usbdev_open() : cannot open device : Permission denied avrdude : jtag3_open_common() : Did not find any device matching VID 0x03eb and PID list : 0x2145 Nevertheless I belong to group dialout and permissions on /dev/ttyACM0 are crw-rw---- Tried everything what was explained on internet about the topic but without any result !! The same issue on the ASUS Thinkerboard !! When I do "Get board info" then arduino detect the board correct !! ( BN:Arduino Uno Wifi Rev2 , VID:0x03eb,PID:0x2145,SN:56008C7BBC944... )
