/var/lib/apt/lists huge in 12.04 - Ask Ubuntu

i noticed /var/lib/apt/lists huge. it's large 86mb. seems little big. normal, if not. should do?

thanks

when run sudo apt-get update (or use refresh button in package manager), list of packages downloaded ubuntu servers. these files stored in /var/lib/apt/lists/.

you can safely remove contents of directory recreated when refresh package lists. if remove files, not run apt-get update fetch lists, commands apt-cache fail provide information (since cache empty).

to shrink directory , speed fetching package lists, consider disabling repositories not need (see how remove repository?). includes ppas (see how can ppas removed?)
