user8355: I have just got Induino R3. I have installed Arduino on my Ubuntu. I tried blink example but it shows error serial port COM1 not found
I think i need to select proper option from serial port. But i can't click on it! 
P.S. I am completely new to Arduino

user8393: Not 100% sure of the specific differences between your board and a normal Arduino[clone], but I've never seen serial devices referenced in Ubuntu via COM# labels(Granted I've only used or needed to use serial type devices in the last year, so I could be a bit under experienced).
Anyhow, usually I find serial devices available at /dev/ttyXXX. On my Lubuntu 14.04 installs, my USB connected Arduinos all show up as /dev/ttyACM#. I have an FTDI programmer I usually use on wifi routers which generally shows up as /dev/tty#.
Rule of thumb in Linux, everything is a file somewhere.
