I'm trying to install PostgreSQL on ubuntu 16.10, I'm running following commands:



$ sudo apt-get update


After executing this command, I get some errors like: E: Failed to fetch http://ams2.mirrors.digitalocean.com/ubuntu/dists/yakkety-backports/universe/binary-all/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.



Then I run:



$ sudo apt-get install postgresql postgresql-contrib


and get:



Reading package lists... Done
Building dependency tree 
Reading state information... Done
E: Unable to locate package postgresql
E: Unable to locate package postgresql-contrib


Any ideas?






apt software-installation updates 16.10 postgresql

          How do so many people here on Academia.SE, and in general, afford lavish higher education programs?

          Clash Royale CLAN TAG #URR8PPP up vote 45 down vote favorite 7 I graduated last year with a BS in Computer Science. I do not come from a particularly wealthy family, (very low middle class), and was only able to afford my education via school loans/scholarships and working low-wage jobs, with no support from my family or anyone else. I realize some scholarship/loan programs extend into grad school. But I don't think those cover all costs. Now I'm lucky enough to have a decent-paying salary in industry, along with benefits and living on my own, and I'm thinking one day (sooner rather than later) I'd like to try my hand at research or continue my degree, but these things cost money, in addition to my regular living expenses.
