Need to get 84.1 MB of archives.
After this operation, 11.3 kB of additional disk space will be used.
E: You don't have enough free space in /var/cache/apt/archives/.
NOTE: I tried bleachbit, sudo apt-get clean, autoclean, etc even dpkg -i --configure -a? and I looked at my root.disk and it says 0.0kb of free room(I think( I don't say verbatim)?) I think there is a bug that causes this problem or I destroyed my system. I have a Dell Vostro 1400 notebook from 2007 with a 1.8Ghz cpu with XD/NX support in the bios enabled, I am not able to fix my problem for my knowledge base is primitive when compared to people with higher experience on Ubuntu Forums. Anything will help. I am still able to use the system and have wifi enabled on Ubuntu OS. Nothing seems to work when I try to apply the security updates it still throws that error.
