sudo apt-get update failes with an Hash Sum mismatch error

Question

As can be seen on the title, I got the "Failed to fetch... Hash Sum mismatch" Error. I have tried this method:

1. Deleting /var/lib/apt/lists/* does not work...

2. Thinking, if I'm behind a proxy, I tried fixing "Hash Sum Mismatch" like this:

   By Creating a file /etc/apt/apt.conf.d/99fixbadproxy with this content

   Acquire::http::Pipeline-Depth 0;

   Acquire::http::No-Cache true;

   Acquire::BrokenProxy true;

3. I tried several other solutions provided on askubuntu however, it doesn't work.

Have a look at my error on the terminal.

Answer 1

This solution finally worked out for me:

1. sudo rm -rf /var/lib/apt/lists/*
2. sudo apt-get update -o Acquire::CompressionTypes::Order::=gz
3. sudo apt-get update && sudo apt-get upgrade

Answer 2

Well, this might be the issue of caches within your ISP. These packages are distributed across multiple locations for making available globally, due to such this packages sometimes not get the updates at a given time in some location so thus you faced this hash sum error.

I would recommend you to perform this action via changing proxy address/ VPN which will change the IP.
