# /etc/apt/apt.conf.d/02no-cache # Disable apt caches. Apt stores two caches in /var/cache/apt/: srcpkgcache.bin is # rather useless these days, and pkgcache.bin is only needed for faster lookups # with apt-cache (software-center has its own cache). Removing those two buys 26 MB # for the price of apt-cache taking an extra two seconds for each lookup. # An image build needs to rm /var/cache/apt/*.bin. However, the next apt-get update # would bring it back, thus the caches need to be disabled in the configuration. Dir::Cache { srcpkgcache ""; pkgcache ""; }
