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.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • The sudo apt-get update error is normal it just means that there is a small error that just prints out those messages, and for cmake did you try downloading and installing manually. cmake.org/download for more info for how to do that askubuntu.com/questions/355565/… – Peyto Feb 25 '17 at 7:22
  • @Peyto The OP would do better to fix his repository than to risk further conflict by trying manual installations. – L. D. James Feb 25 '17 at 7:56

    Will you edit your question and append the output of this command: egrep -v "^#|^$" /etc/apt/sources.list.d/*;egrep -v "^#|^$" /etc/apt/sources.list – L. D. James Feb 25 '17 at 8:09

    If you are using Ubuntu 16.04, why do you have yakkety repositories in your sources? – Zanna Feb 25 '17 at 9:43

You can try:

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

apt bug explained here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=810796

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.

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.
