[Bug 1373598] Re: apt-get update fails, hash sum mismatches with de.archive.ubuntu.com

Sat May 7 07:06:31 UTC 2016

I've been having the same problems while running apt-get update,
including 'hash sum mismatch' and 'BADSIG' errors. I tried the
following:

1. Downloading updated keys
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys <KEY_NAME>
sudo apt-get update

2. Clean cache then update (some report success with repeated cycles of this)
sudo apt-get clean
sudo apt-get update

3. Clear out the list files completely, or just the partials
sudo rm -f /var/lib/apt/lists/*
sudo rm -f /var/lib/apt/lists/partials/*
sudo apt-get update

4. Clear out the status file as it may be corrupted
sudo rm /var/lib/dpkg/status
sudo touch /var/lib/dpkg/status
sudo apt-get update

5. Disable proxy to ensure direct download from the mirror
sudo apt-get -o Acquire::http::No-Cache=true -o Acquire::BrokenProxy=true -o Acquire::http::Pipeline-Depth=0 update

6. Try changing to another mirror in "Software & Updates"
I tried the following:
* ubuntu.ctu.edu.vn           (Vietnam     - failed - my original mirror)
* ubuntu.01link.hk            (Hong Kong   - failed)
* archive.ubuntu.com          (Main        - failed)
* mirror.switch.ch            (Switzerland - failed)
* mirror-fpt-telecom.fpt.net  (Vietnam     - success - a mirror hosted by my current ISP)

TL;DR Only changing the mirror was able to solve this problem for me.

Title:
  apt-get update fails, hash sum mismatches with de.archive.ubuntu.com

Status in apt package in Ubuntu:
  Confirmed
Status in ubuntu-release-upgrader package in Ubuntu:
  Invalid

Bug description:
  1. Release: 
  Description:	Ubuntu 14.04.1 LTS
  Release:	14.04

  2.  not a package. The whole distro is broken.

  3. I always expect apt-get update to work, at least with Ubuntu's own
  repositories.

  4. "apt-get update" failed, and later "apt-get dist upgrade"

  It started with this when doing a normal "apt-get update"

  W: Failed to fetch http://de.archive.ubuntu.com/ubuntu/dists/trusty-
  updates/main/source/Sources  Hash Sum mismatch

  W: Failed to fetch http://de.archive.ubuntu.com/ubuntu/dists/trusty-
  updates/main/binary-amd64/Packages  Hash Sum mismatch

  W: Failed to fetch http://de.archive.ubuntu.com/ubuntu/dists/trusty-
  updates/universe/binary-i386/Packages  Hash Sum mismatch

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

  When doing a dist-upgrade, I then got this:
  E: mkinitramfs failure cpio 141 gzip 1

  And later this at the end:

  E: Sub-process /usr/bin/dpkg returned an error code (1)
