If all else fails, try this link. I do not have the board but have for some devices had to install udev rules. This is covered at the end of the article.https://majenko.co.uk/blog/diagnosing-arduino-problems-linux
# echo 'SUBSYSTEM=="usb", MODE="0660", GROUP="insert_your_group"' > /etc/udev/rules.d/00-usb-permissions.rules# udevadm control --reload-rules
Hello again,I restarted my Fedora 29. Then I tested blink sketch on «Arduino uno wifi rev2» with the same error:avrdude: usbdev_open(): cannot open device: Permission deniedavrdude: jtag3_open_common(): Did not find any device matching VID 0x03eb and PID list: 0x2145S'ha produït un error mentre s'enviava el programari.Thanks for your help.What can I do ?Carles.
still cannot upload a simple blink example into it.
there is not enough information found on Arduino website regarding the board and issue.
avrdude: usbdev_open(): cannot open device: Permission deniedavrdude: jtag3_open_common(): Did not find any device matching VID 0x03eb and PID list: 0x2145Errore durante il caricamento dello sketch.
avrdude: usbdev_open(): WARNING: failed to set configuration 1: Device or resource busyavrdude: WARNING: invalid value for unused bits in fuse "fuse5", should be set to 1 according to datasheetThis behaviour is deprecated and will result in an error in future versionYou probably want to use 0xcd instead of 0xc9 (double check with your datasheet first).

My first problem with this brand new board:
I have the same problem using the uno wifi rev2 with Windows 10 edu and arduino IDE 1.8.9(Windows Store 184.108.40.206)I can upload sketches over usb and have SimpleWebServerWifi running. The problem is uploading sketches when the cable is disconnected.There is a connection and I can ping (pathping from command prompt): Tracing route to arduino-d148.home [192.168.1.186] over a maximum of 30 hops: 0 Huginn-win.home [192.168.1.150] 1 arduino-d148.home [192.168.1.186] Computing statistics for 25 seconds...
