Ubuntu Uninstall clean software (including configuration files)

Var/cache/apt/archives occupying huge space

I am in the process of cleaning up my system. and I see a lot of space occupied by this folder /var/cache/apt/archives (1.5GB). Is it absolutely necessary to keep all these archives?

You don ' t need to keep them around if you don't want them. Executing a

sudo apt-get clean

would clean the directory.
