Hash sum mismatch (only for openjdk-11-jdk)

I was installing Java yesterday. I had faced lot of problem. I had fixed most of them. But I had changed Hash that's what I think. I don't remember which command I had executed since I had executed lots of command and visited lots of site. Now, whenever I go to install something I get an error which says `Hash Sum mismatch`. 

```bash
sudo apt install openjdk-11-jdk

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
```

I had tried to update my system with --fix-missing. I got no error. I had tried following commands

```bash
sudo apt-get update
sudo apt-get update --fix-missing
sudo apt-get upgrade
```

I got no error. I am just getting that error whenever I try to install something.

I had cleaned my system and updated yesterday. 

```bash
sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
sudo apt-get update --fix-missing
```

I had removed some files also. 
```bash
sudo rm -rf /var/lib/apt/lists/*
```

I think `clean` and above command had done same process.  https://askubuntu.com/a/41618/1439690

I have recently installed a random application in my system called Audacious. I got no error for that. But I only get the error for openjdk-11-jdk. Even if you look at output of that installation than you will notice my system is saying they need 37.2 MB `37.2 MB/264 MB` while the package is 264 MB.
