Just installed a new Grml system, annoyingly from a bit too far outdated image so aptitude fails to handle everything at once…
Here is the error:
Aha, too many open files.. So I had to install everything piecewise in a disturbing manner..
iptables 1.4.6-2 -> 1.4.10-1 before
xtables-addons-common 1.23-1 -> 1.26-2 is a bad idea and fails for some reasons. So try to do it the other way round.
