Hash-sum mismatch on apt-get

[maarten2001]

I always get the "Hash-sum mismatch" error, and I have no idea why. Here is the log:

And I don't know if everyone has this problem. I tried to reinstall Raspbian more then 5 times, but that didn't help. I am using NOOBS, but when I use the Raspbian image with Win32 Disk Imager I get the same errors. What I like to know is if you have these problems too, and how to fix this.

[maarten2001]

Is no one having this issue?

[DougieLawson]

apt-get is working OK for me with the English mirrors.

I assume you've tried again in case it was a transient error.

[maarten2001]

I am trying for 4 days now and it still doesn't work. Can you tell me how I cange the mirror? (And which mirror you are using?)

[rpdom]

One of the most common reasons (other than a bad mirror) for this sort of error is lack of space on your filesystem.

First check how much free space you have with "df -h /". If the available space seems fine, you can manually verify what is being downloaded with a few commands:

Code: Select all

pi@raspi:~$ cd /tmp
pi@raspi:/tmp$ # Download the gzipped Packages file first (you don't need to type this comment line)

You can see that in my case the 8d9e...3a74 value matches, so my download is good.

Give it a try and let us know what you get as a result.

Yes! It works now! I just plugged in my wifi adapter i bought and it works!

[Harold]

I had the exact same Hash Sum mismatch on the armhf_Packages. Tried all availables fixed (removing partial downloaded packages, etc...). Tried different raspbian version (jessy). Tried an 'supported' SD-card (Adata 8GB) and multiple other SD-cards.

All with the same result!

So the next thing I tried was using the SD-card I made (the Adata one) in another Raspberry PI. First it gave me the same Hash Sum mismatch error. But after removing all partially downloaded packages (rm -rf /var/lib/apt/lists/partial) and then doing an 'apt-get update & apt-get upgrade' it worked!!!

Now I was finally also able to do an firmware upgrade (rpi-update). But its the wrong Raspberry PI that I'm updating

So my conclusion is that there is something wrong with the ethernet connection of my first Raspberry PI. I ones used XBMC on it and had issues when tying to watch HD movies on it (artifacts in the video). Must be because this Raspberry PI has problems with its ethernet connection.

I'm going to ask for an RMA from RS Componets for this Raspberry PI. Hope that they are going to swap it for a 100% working version.

Have you tried a wifi adapter yet? It fixed it for me..

I had the same problem. I gave up and switched to arch

[entekathukal]

Hi,

I got it working from the following....

Do these commands..............

Code: Select all

sudo apt-get clean
sudo rm /var/lib/apt/lists/partial/*
sudo nano /etc/apt/sources.list

delete everything and add the following lines to your sources.list file...........

Code: Select all

deb http://archive.raspbian.org/raspbian wheezy main contrib non-free
deb-src http://archive.raspbian.org/raspbian wheezy main contrib non-free

use this command for public key.............

Code: Select all

wget http://archive.raspbian.org/raspbian.public.key -O - | sudo apt-key add -

Then do ..............

Code: Select all

sudo apt-get update

Done!!! Sorry for my bad English.....

[SeaDude]

Had this same issue (which landed me on this page!).

My fix was looking carefully at the mirror url within the sources.list file. Somehow the mirror url showed an extra "http:" in front of the url. I removed the additional characters, saved the file, and sudo apt-get'd just fine.

Might help someone!

[Lope]

I had the same problem, researched it, tried all the suggested fixes for failed apt stuff, like this
rm /var/lib/apt/lists/partial/*
wget https://archive.raspbian.org/raspbian.public.key -O - | sudo apt-key add -
(make sure you use https! I see a lot of suggestions to get raspberry pi public keys with http. very insecure!)

anyway. After I kept getting hash sum fails I just updated to jessie. Just change wheezy to jessie in your /etc/apt/sources.list file

[pfmelamed]

You can do:

sudo rm /var/lib/apt/lists/* -vf

sudo apt-get update

And Go...

Doesn't work. I think that somehow the ethernet chip is corrupted or that there is a bad connection on the board somewhere. This thread is old, but the problem still occurs on the newest version of raspbian.

sudo rm /var/lib/apt/lists/* -vf

This solved the issue I was having with Stretch. Fresh image right off the website yesterday (12/27/2017) sudo apt-get update would fail with hash-sum mismatch.

It now updates fine. (And very quickly)

Thanks!

[John Mc]

I too was having the hash sum mismatch errors when I tried to apt-get update the copy of 2017-11-29-raspbian-stretch I downloaded earlier today.

I tried the

Code: Select all

sudo rm /var/lib/apt/lists/* -vf

command as recommended above. Things seemed to change, and the downloads progressed differently than before, but I still get the mismatch error.

Here is what I'm seeing now:

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

Also can someone explain what that "sudo rm /var/lib/apt/lists/* -vf" command is actually doing? Is it safe to assume no functionality is lost by removing these items?

[John Mc]

Well, not sure what was going on. Multiple attempts at apt-get update filed with the "hash sum mismatch" error. I noticed that the actual downloaded size was much smaller than the expected file size. I also noticed that my internet connection had slowed to a crawl (despite the fact that all the kids were in bed and their various devices shut down).

Unplugged my DSL modem, waited a couple of minutes and plugged it back in. My internet connection is now much faster (speed tests show expected speeds). Apt-get update worked normally (I suspect the update was timing out due to my poor connection??), but apt-get upgrade had an error. I've tried several times, including going back to

sudo rm /var/lib/apt/lists/* -vf
sudo apt-get update
sudo apt-get upgrade

Still getting errors on upgrade when it gets to the pythin3 upgrade:

Should have looked a bit more first. Found the solution to the python3 upgrade problem in this thread:
python-scrollphathd upgrade problem

(note minor typo in the first of the 2 commands mentioned: "archive" should be "archives")

[sparson]

I was having this problem, it turned out to be a bad usb wifi causing it.

I've tried the fix above, i.e. sudo rm /var/lib/apt/lists/* -vf
and then doing another apt-update, but still the same result.

So downloading the file to /tmp with :-
wget http://archive.raspberrypi.org/debian/d ... ackages.gz

and then getting the hash: -

wget -O - -q http://mirrordirector.raspbian.org/rasp ... ch/Release | grep main/binary-armhf/Packages.gz

comparing that I get: -

md5sum Packages.gz
dc9b089480ad12149d673b1667bc8f25 Packages.gz

And I've tried the same on an Opensuse machine as well, as a cross check to make sure my wifi and SD card are ok, same results on the Opensuse machine.

Any help appreciated.

After struggling with this issue for several hours, running all the commands prescribed here, I decided to reboot my router and voila!

I can't understand what the matter was, but I guess I can get back to work now
