Eu sou um novato do Ubuntu e gostaria de instalar o zlib1g-dev no Ubuntu 16.04.3 LTS.
O comando:
sudo apt-get install zlib1g-dev
ressurge no seguinte erro:

Reading state information... Done

Estou pesquisando, mas não sei como consertar isso.

Acabei de ter o mesmo problema ao tentar instalar algumas dependências para compilar o Ruby.
A maneira mais fácil de sair dessa miséria é anotar o pacote e a versão na segunda à última linha: zlib1g e 1:1.2.8.dfsg-2ubuntu4 , em seguida, emita o seguinte comando:
$ sudo apt install zlib1g=1:1.2.8.dfsg-2ubuntu4
Isso fará o downgrade de zlib1g para a versão exigida e a instalação deverá ser bem-sucedida posteriormente.
Tente examinar com isto:
sudo aptitude install libssl-dev
Receba a mensagem:
The following packages have unmet dependencies:
zlib1g-dev : Depends: zlib1g (= 1:1.2.8.dfsg-2ubuntu4) but 1:1.2.8.dfsg-
2ubuntu4.1 is installed.
The following actions will resolve these dependencies:
Keep the following packages at their current version:
1) libssl-dev [Not Installed]
2) zlib1g-dev [Not Installed]
Accept this solution? [Y/n/q/?]
Então 'e' e faça downgrade do seu zlib1g-dev.
Isso resolve o seu problema?
