Where is coreutils in ubuntu - marginal?

The coreutils is significant Essential: yes, so it is constantly consisted of in an installment, and also dpkg will certainly advise you in an instead non - ignorable means if you attempt to remove it. Plans do not need to proclaim dependences on crucial plans, unless they require a certain variation (as an example, dpkg (an additional crucial plan) relies on coreutils (>= 5.93-1) in Ubuntu 10.04).

It is a dependence of both the bit and also dpkg so I'm rather particular it'll get on ubuntu - marginal.

aptitude search '~E'
