@arunksoman thanks for the steps
but the thing is I don't have issues with port now, I was curious how it got resolved without going through the usual steps but by using sudo command. -
@Abhay What did you mean by usual steps?

@arunksoman by usual steps I meant adding our user to the group.
ie the step
sudo usermod -a -G dialout <username> -
@Abhay I think most probably you might have done this earlier while installing Arduino.

@arunksoman thanks,
I will look more into it. Thanks again
