I have a Ubuntu 16.10 64 bit machine.

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

When I run sudo apt-get update I get the following error.

You can try:

sudo apt-get -o 'Acquire::http::No-Cache=true; Acquire::http::Pipeline-Depth=0;' install NAMEHERE

From system settings select software & updates. It will take some time for update your OS from server for India, after system update done try to install software what you want.

Remove the repository entry causing the problem.

The problems you are having is a result of installing a repository ahead of your Ubuntu version. This causing the unmet dependencies breackage you are seeing.

The resolution is to remove the offending repository entry. You can identify this by the yakkety reference in your error message:

Err:1 http://us.archive.ubuntu.com/ubuntu yakkety/main amd64 cmake amd64 3.5.2-2ubuntu1

Remove that entry, then update your repository cache with:

$ sudo apt update
$ sudo apt upgrade

If you need to install something that is made for a newer OS release, you will have to manually compile it and it's neccesary dependencies.

Alternatively you can look for a PPA that is made for your Ubuntu installion, which you have indicated as Ubuntu 16.04.
