The follow error occurs when running apt-get update:

A error occurred during the signature verification.
The repository is not updated and the previous index files will be used.
GPG error: http://za.archive.ubuntu.com precise Release.
Failed to fetch http://za.archive.ubuntu.com/precise/Release

I am running the update from a fresh install. The only configuration change I made was to change the network from DHCP to static.

Here is the error output from the apt-get update command:

Here is my /etc/apt/sources.list file:

    What will the mv and mkdir commands attempt to do? I am updating from a fresh install with a manual network configuration afterwards. – Hendré Oct 26 '16 at 11:15
  • mv for move and mkdir for make directory – Naresh S Nash Oct 26 '16 at 11:22

    That is not what I meant. :) What will the commands do to the apt system. – Hendré Oct 26 '16 at 11:24

It appears the URL for fetching your package list is wrong. Please check /etc/apt/sources.list if the address is http://us.archive.ubuntu.com/ubuntu/ ; to me it appears as if the entries in your sources.list miss the ubuntu/ part.

  • else if you have an gui, just try the solution in the comment by M.Beccera – db429 Oct 30 '16 at 16:49
  • The URLs cannot be wrong. I made no edits to the sources.list file. This happens after a fresh install. The only configuration I made was to change the network configuration from DHCP to static. – Hendré Oct 31 '16 at 6:21
  • @Hendre pls just check your etc/apt/sources.list - I believe you, you did not change anything, yet simply run cat /etc/apt/sources.list and we will see. Because your system rightfully complains that it can not find the file under that url, because the file is not there. – db429 Nov 1 '16 at 10:37
  • I updated the question with sources.list output. – Hendré Nov 1 '16 at 11:03

    okay I googled "apt hash sum mismatch" and mostly all solutions that came up are a variation of @Naresh S Nash's solution; his commands in a simple term move the apt list-cache to /tmp and then forces to get them again, thereby it will also pull new hash sums. – db429 Nov 1 '16 at 15:01
