How can I update BOSS Linux by terminal only?


In the directory /etc/apt/ and /etc/apt/sources.d/ you will found many .list file. Open them as root in vim or nano or gedit and replace all 'anokha' by 'unnati' and all 'eduboss-3.0' by 'eduboss-4.0'. Then run, sudo apt-get update if any error occurs, then reboot the system first and then run, sudo apt-get update sudo apt-get upgrade But before doing these make sure you are backed up every important document because you are upgrading to the latest release it may cause system break.

Good luck.


write the following command in the terminal "sudo apt-get upgrade". It will upgrade all the packages and install them automatically and after installation is completed restart your computer.

    That is unlikely to work until the apt-get update has completed successfully, and the OP is illustrating a situation where it's not. – roaima Sep 10 '17 at 13:11
