[Bug 1089070] Re: Could not open file /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_quantal_main_binary-amd64_Packages - open (24: Too many open files)

[Julian Andres Klode]

Check that you have less files in /var/lib/apt/lists than ulimit -n has
a value. You probably have too many repositories or too low a ulimit.
Otherwise, open a new bug with ubuntu-bug/apport.
