Hash fail after apt-get update

[Coxeroni]

Since yesterday I am getting the following error after updating the package list:

Code: Select all

W: Size of file /var/lib/apt/lists/partial/mirror.et.uni-paderborn.de_raspbian_r
aspbian_dists_wheezy_main_binary-armhf_Packages is not what the server reported
7368242 9454002
W: Failed to fetch gzip:/var/lib/apt/lists/partial/mirror.et.uni-paderborn.de_ra
spbian_raspbian_dists_wheezy_main_binary-armhf_Packages  Hash Sum mismatch
 
E: Some index files failed to download. They have been ignored, or old ones used
 instead.

Deleting that file and changing the mirror didnt change anything.
Am I the only one with that problem and how to solve it?

Thanks in advance

Seems like a problem with the mirror you are using. Either wait a bit to see if it clears up or use a different mirror.

i'm getting this too. i'm also getting a 404 Not Found when trying to install motion but i don't know if this is related or not since i'm a bit new to repositories and such

Failed to fetch http://mirrordirector.raspbian.org/rasp ... _armhf.deb 404 Not Found

when looking in the above directory i see that libpq5_9.1.5-1_armhf.deb must have been replaced with libpq5_9.1.5-2_armhf.deb on 21/09/12.

does someone need to be notified of this or is it just one of those things that i just have to wait for?

thanks.

btw. i did apt-get update beforehand, yes.

Can you try running apt-get update again.

[t-47]

no change unfortunately...

atp-get update...

W: Failed to fetch gzip:/var/lib/apt/lists/partial/mirrordirector.raspbian.org_raspbian_dists_wheezy_main_binary-armhf_Packages Hash Sum mismatch

apt-get install motion...

Well theres your problem, you aren't getting the updates package lists because of a hash sum mismatch.

However I don't think it's a problem on our end because if it was we would be getting a lot more complaints. Probablly something messing with the data in transit.

How do you connect to the internet?

[plugwash]

Please try the following

apt-get install apt-transport-https ca-certificates

Then point your sources.list at https://archive.raspbian.org/raspbian and try running apt-get update again.

Please try the following

apt-get install apt-transport-https ca-certificates

Then point your sources.list at https://archive.raspbian.org/raspbian and try running apt-get update again.

Will try that this evening, thanks.
Still news from my side:
The problem only occurred while I was connected to "my" VPN server. I disconnected, ran apt-get update and everything was fine...
So in my case there must be an issue either with the VPN itself or with the VPN and apt, which I don't have a clue what could be wrong there.

thanks a lot plugwash. that did the trick nicely

kind of irrelevant now but since you asked... i connect to the internet via wifi through virgin media and i don't use a vpn. i'm using a fresh install of the 2012-09-18 Wheezy image which had no changes at the point of getting that error.

I've just had exactly the same problem. I tried to change the sources.list to point to https (after aptitude install apt-transport-https), but that failed.

I've managed to resolve it by deleting the following and re-running aptitude update:

Code: Select all

/var/lib/apt/lists/partial/mirrordirector.raspbian.org_raspbian_dists_wheezy_main_binary-armhf_Packages*

I had the same problem and I tried deleting from the "partial" directory with no success. There is a bad mirror and I have no idea which one it is but it may be geographically constrained which would limit the persons experiencing the problem.

Here is what I did as a workaround:

Edit: /etc/apt/sources.list
Replace

Code: Select all

deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi

with

Code: Select all

deb http://distribution-us.hexxeh.net/raspbian/archive/raspbian/ wheezy main contrib non-free rpi

or some other appropriate value from the following list: http://www.raspbian.org/RaspbianMirrors

then

Code: Select all

sudo rm -f /var/lib/apt/lists/*
sudo rm -f /var/lib/apt/lists/partial/*
sudo apt-get update

Hey mage7223,

thanks, for your solution. This works fine for me

I can't access etc/.... it says permission denied.
so i used nano/etc..., but still as i tried to save the changes it says: [ Error writing /etc/apt/sources.list: Permission denied ]
help please!

[plugwash]

You need to be root when making the changes.

[plugwash]

There is a bad mirror

Unfortunately that doesn't explain the problems you are getting. The dists directory is served directly by mirrordirector.raspbian.org, it is not redirected to mirrors.

[Iceshadow]

Thanks you all, it workls fine now

[crlsgomez]

You need to be root when making the changes.

how do I do it as root?

I fought with this for the better part of two days.

Make your life easy and just reinstall the OS.
