Slow update speed on Kali Linux

How to fix slow update speed on Kali Linux ?

Not only you but most people face this problem after installing Kali Linux. Though the solution is much simpler than you think.

You just have to update your mirrors in Kali Linux

Open terminal and type

sudo nano /etc/apt/sources.list

You can use any text editor you want (like vim)

After this your sources.list file will open 

deb https://mirrors.ocf.berkeley.edu/kali kali-rolling main non-free contrib

deb-src https://mirrors.ocf.berkeley.edu/kali kali-rolling main non-free contrib

Just add above two lines. Delete any previous sources (if exist) otherwise you will get duplicate sources error when you will run update command next time.
