[Ak1815]

Brothers, I am running sudo apt update and getting Hash Sum mismatch error:

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

I have only showed you the code from where the error starts..

I know nothing about Hash Sum Mismatch, it will be helpful if you guys will make me understand about the solution.

[Mr_Magoo]

Looks like either the download was corrupted, or the package maintainer included incorrect hashsums.

Try:

1. sudo apt clean
sudo apt purge {package}
   ... where {package} is whatever package you're attempting to install (just to be sure there's not some problem caused by it already being installed).
   Download and attempt the installation again.

2. If you still get the error, you'll have to contact the package maintainer to see if they've messed up the hashsums.

[Ak1815]

Thank You so much for the response.

The first solution didn't work. Here is the output of the command:
sudo apt purge Index of /zorinos/apps/ubuntu focal/main i386 Packages
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package Zorin OS in Launchpad
E: Unable to locate package focal
E: Unable to locate package i386
E: Unable to locate package Packages

Also, I don't know how to contact the package maintainer.
I am desperate to use Zorin OS as my main OS.

The error (Hash Sum Mismatch) is associated with this link: Index of /zorinos/apps/ubuntu focal/main i386 Packages [46.8 kB]

Also I tried to update the system through the Software Updater.
Here are the images:

As you can see when the updater completes checking the link in which the error occurs in the terminal, it says Failed to download repository information.

I think their is only problem with this link which I have given above.
Please help because I love Zorin OS

[Storm]

Is it Zorin 15.3 you are using?

[Ak1815]

No it is Zorin OS 16.1 Core

[Storm]

Why do you have 32-bit repository in your list?

[Ak1815]

I am unable to understand, means What ?

[Storm]

i386 is 32-bit

Got to software center and click on the burger menu. Pick Software and Updates. Under Other Software, try tick/untick the offensive repoisories.

[Ak1815]

In the about section it is showing 64 bit.

Offensive Repositories meaning the one in which I am getting the Hash Sum Mismatch ?

[Storm]

Yes, try untick the i386 repositor(ies).
Zorin 16 only comes as 64-bit where Zorin 15 comes both as 32 and 64 bit. That's why I was asking.

[Ak1815]

Please tell me which one

[Storm]

Okay check;

cat /etc/apt/sources.list
ls -a /etc/apt/sources.list.d

[Ak1815]

Here are the output:

[Storm]

Okay. No indication of 32-bit in the source.list
Try untick this one (you can always enable it again).

[Ak1815]

Yes, I did. But after unticking, I clicked on close and it showed 'Refreshing Software Cache'. Then this came up.

[Storm]

Try do the same with that.

[Ak1815]

means ?

I ran the sudo apt update command .
Here is the output:

[Storm]

Untick it in your source.list

[Ak1815]

what is source.list I don't know..

[Storm]

Sourcelist is the list of different repositories that you downloading software and updates.
