E: Some index files failed to download. They have been ignored, or old ones used instead.

I googled about this issue and found some related ones but none of those solutions worked for my case.

Note:- I am using Ubuntu version 15.10.

Please help. I am new to linux.

    Oh, so ubuntu 15.10 has reached its EOL stage. Thanks alot for saving my time. :( Although I already wasted a lot while surfing. – Phantom Coder Nov 21 '17 at 19:39

    It would be fastest to back up your data to an external drive and reinstall. – chaskes Nov 21 '17 at 19:40
