Many developers and programmers might be looking for Microsoft Windows fonts. It is a third part codec for Ubuntu. So sometimes installation will not succeed because third part packages will have some Hash Sum mismatch.
( Hash Sum mismatch :- Ubuntu validates all packages and software which are not in its repository using a Hash value. If this value is not authenticated we cannot install it using apt-get install command or Ubuntu Software center and need to install manually )
So I have provide all methods of installation.
1. Using terminal
Run below command as sudo
$ sudo apt-get install ttf-mscorefonts-installer
2. Using Ubuntu Software Center
Enter ttf-mscorefonts-installer and accept EULA agreement
