Hi all.
Guys please help!
What I did on ubuntu trying to load in the Arduino Ide to the Board.
All compiles well, but when you send to the Board, then writes this error:
avrdude: ser_open(): can't open device "/dev/ttyUSB0": Permission denied
ioctl("TIOCMGET"): Inappropriate ioctl for device
Problem uploading to board.
What I just tried: I added your user to dialout, open the administrator folder and assigned to ttyUSB0 rights for all to read and write, create a separate file describing the other rules for this interface, just through the console using chmod appointed rights to a+rw, and so on, yet nothing helped!
Very hope for your help, there has to be a way to program the Board program on ubuntu.

I did so on xubuntu16:
sudo tar-xvf arduino-1.8.4-linux64.tar.xz -C /opt/
cd /opt/arduino-1.8.4/
chmod +x install.sh
./install.sh
Dobavlenie the user to the group dialout:
sudo usermod -a-G dialout prog1
P. S. the work of the M0 and Leonardo prevents modemmanager , I delete it.
sudo apt-get remove modemmanager

What I just tried: I added your user to dialout

that's right. After add need relogin (logout and login, you can do su - $USER) - and all should earn. To check-in the output of the command groups in the terminal in which you run avrdude should appear in the group dialout.

opened using the administrator folder and assigned to ttyUSB0 rights for all write and read

just using the console using appointed rights chmod a+rw

permissions are assigned automatically when the device file is created udev'ohms.

create a separate file describing the other rules for this interface
