A few days ago I got some time to set up Kali Linux on VMware everything seems fine until I tried to update it using apt-get update I get this annoying error

E: Some index files failed to download. They have been ignored, or old ones used instead.
the problem clearly must be in the sources.list file of Kali Linux … I have tried to fix it in many ways but I always end up where I started Hash Sum mismatch is showing up over and over, things seem too complicated for me but the fix was simple really simple ! and here it is,
update your Repositories in sources.list file to :
deb http://http.kali.org/kali kali-rolling main non-free contrib
Save and close the file
Clean, update, upgrade and dist-upgrade your Kali installation
apt-get clean && apt-get update && apt-get upgrade -y && apt-get dist-upgrade -y
apt-get hash sum mismatch
It is estimated that many people have encountered this problem.
The main idea is: some of the network providers you use will set up some transparent caches to increase the internal speed of the network and reduce the traffic of exports. Some files you obtain are not real files on the source server, but are obtained from the cache When some of the verification information obtained in the cache is inconsistent with the source, it naturally prompts that the verification has failed and cannot be updated.
This problem is actually related to the format design of the apt software repository. The newly released version of the software warehouse is updated more frequently. The files in the cache should be updated synchronously. Unfortunately, because of the speed of multiple mirror sites, the cache cannot guarantee consistency.
When the network provider is strong enough to not set up a transparent cache, this problem does not exist. This is why some people report that the use of wireless network cards (mobile, Unicom’s 3g network) is all OK, and it is not enough to switch back to Great Wall Broadband or Broadband.
The above is the real cause of the problem.
My home network is broadband communication, there is no doubt that this network ISP will definitely set up transparent cache.
The solution is simple, just bypass the cache and go directly to the site.
How to bypass this cache set by ISP is the same as bypassing the Great Wall firewall.
I found a free ssh service proxy,
and then installed a proxychains, set up your proxy in /etc/proxychians.conf to
use proxychains sudo apt-get update to
update normally (no matter which source you update, domestic or foreign)
if You don’t think the proxy is fast enough, just update the source index and sudo apt-ge install xxx directly when installing the software. There is no problem installing various software in the software center.
The fundamental solution to this problem is related to the format design of the apt repository.
However, ISPs in Europe and the United States seem to have good networks and fewer caches. There are not many people who raise this issue. Therefore, it is unpredictable whether they will improve the design.
There is another situation that will naturally be resolved, that is, after the source index is gradually stabilized, your ISP’s cache will be consistent with the real data, and the update will naturally be fine.
It must be updated frequently when new versions are released. It is estimated that most of the new version control cannot wait.
The above is about the real cause of Hash Sum mismatch problem when updating the source index, and the solution, I hope it will be helpful to all friends
can you help me it dont work for me
uninstall the package that are casing the error …
if you don;t know it just copy and past the error code in here and i will tell you what to do

E: Unable to fetch some archives, maybe run apt-get update or try with –fix-missing?”
This is my sources.list:
“# See https://www.kali.org/docs/general-use/kali-linux-sources-list-repositories/
#deb http://http.kali.org/kali kali-rolling main contrib non-free
# Additional line for source packages
deb http://http.kali.org/kali kali-rolling main contrib non-free
#deb https://assets.checkra.in/debian /
#deb https://assets.checkra.in/debian /”
You can contact me on here but there’s probably a bigger chance of me answering on Discord (depending on when someone answers).
Discord: Emport#6532
This is how it worked for me.
Remove all the lines starting from deb and paste the below lines in sources list.
sudo nano /etc/apt/sources.list
Update the below lines:
deb https://http.kali.org/kali kali-rolling main contrib non-free
deb-src http://http.kali.org/kali kali-rolling main contrib non-free
Save & Exit out of the Nano.
Run the below command and you should be good to go.
sudo apt-get clean && apt-get update && apt-get upgrade -y && apt-get dist-upgrade -y && apt autoremove -y
