I checked the duplicate questions with

Hash Sum mismatch

And ran these commands

sudo rm -rf /var/lib/apt/lists/*

sudo apt-get update

Things ran okay till I tried to install apache2 using the command 

sudo apt-get install apache2

Which is when I get a Hash Sum Mismatch and also Bad header line Bad header data

I also checked the question to use internet through a proxy address.

The IP 192.168.1.151:808 in the error code is a proxy address for accessing the internet. I am using it by mentioning the following lines in the /etc/apt/apt.conf file

Acquire::http::Proxy "http://192.168.1.151:808";
Acquire::https::Proxy "http://192.168.1.151:808";
Acquire::ftp::Proxy "http://192.168.1.151:808";

How can I install apache2 without any errors?

Using sudo apt-get install software instead of sudo apt install software fixes the problem.

  • I just got the same thing with emacs25, but sudo apt-get install emacs25 resulted in the same Hash Sum mismatch. (I also tried deleting the files in the lists directory first.) I just upgraded from 16.04 xenial to 18.04 bionic, so the upgrade removed emacs24. – Trey Nov 30 '18 at 22:19
