Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libgnutls-dev : Depends: libgnutls30 (= 3.4.10-4ubuntu1) but 3.4.10-4ubuntu1.4 is to be installed
                 Depends: libgnutls-openssl27 (= 3.4.10-4ubuntu1) but 3.4.10-4ubuntu1.4 is to be installed
                 Depends: libgnutlsxx28 (= 3.4.10-4ubuntu1) but it is not going to be installed
                 Depends: nettle-dev but it is not going to be installed

                 Depends: libidn11-dev (>= 1.31) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

A mensagem de erro (xxx existe mas xxxx + a versão deve ser instalada) não faz sentido algum. Não há nada para ser instalado além dos pacotes listados.

sudo apt install -f resulta em nada:

Answer 1

A versão atual do libgnutls-dev no xenial é 3.4.10-4ubuntu1.4 .

Parece que você desativou o repositório xenial-updates .

• Na área de trabalho, abra Software & amp; Atualizações ( software-properties-gtk ), vá para a aba Atualizações e confira xenial-security e xenial-updates .

• No servidor, você deve ter a seguinte linha em /etc/apt/sources.list :

  deb http://archive.ubuntu.com/ubuntu xenial-updates main restricted universe multiverse 
  

E tente instalá-lo novamente.
