I have downloaded eclipse neon 64 bit from eclipse's official website. I followed the steps mentioned in How to install Eclipse, but wasn't able to install eclipse. So, I did some more research and I found How to Install The Latest Eclipse in Ubuntu 16.04, 15.10. When, I run eclipse-inst (the 3rd step in the second link), I get a length error on my screen about which I have no idea. The error that I get is here error when i run ecipse-inst.
Please help me to find a solution for this problem. I am very new to linux (I had installed ubuntu just 2 days ago). Thank you.
