Problem uploading the code into an Arduino Uno I was trying to upload code for a blinking LED. It is a new Arduino Uno board. Any further help will be appreciated.I got the following error:

Info.: OS- Ubuntu 16.04
Software: Arduino IDE 1.8.5

I could not see any port.
I have tried dialout. But still it is not working.
I also have a confusion, i.e. the Programmer menu shows AVRISP mkll.

If anyone wants any information, please do comment.
Error:

An error occurred while uploading the sketch
avrdude: ser_open(): can't open device &quot;COM1&quot;: No such file or directory`
Ubuntu and other Linux operating systems don’t name the serial ports “COM1” or similar. 

They use special files like

/dev/tty.[something]


The [something] depends on the USB device driver. The IDE should list available serial ports in the Port selection menu.
