Question

I am Linux Mint user.I am dealing with Arduino Yun.I am compiling Arduino program.After that I am uploading to Arduino Yun.Then I get these error.Can you help me?

Answer 1

I was struggling with this issue for quite a while earlier today and all the solutions I found online didn't help. All of the error messages I was receiving were exactly identical to the ones on forums like this.

Then I realized that I made the most embarrassing mistake which was my cable wasn't properly plugged in.

So, please, before you scour the web over an hour trying every solution on the internet, please make sure your cables are plugged in correctly.
