I'm learning ubuntu from scratch as I do really like it, and in "hard" mode, only ssh access. I've managed to solve a lot of questions along the path but not this one.

When I was trying to install some package, I got unmet dependencies of that package (no matter which one, I've tried some and all of them show the same issue) and from webmin (package I downloaded, use sudo apt-get install webmin_1.810_all.deb but I did not install yet as it was showing unmet dependencies).

As I do get the webmin unmet dependencies with all packages I try this:

sudo apt-get install

and it also show the webmin unmet dependencies:

Leyendo lista de paquetes... Hecho

Creando árbol de dependencias

Leyendo la información de estado... Hecho

Tal vez quiera ejecutar «apt-get -f install» para corregirlo.

Los siguientes paquetes tienen dependencias incumplidas:

 webmin : Depende: libnet-ssleay-perl pero no está instalado

          Depende: libauthen-pam-perl pero no está instalado

          Depende: libio-pty-perl pero no está instalado

          Depende: apt-show-versions pero no está instalado

E: Dependencias incumplidas. Pruebe de nuevo usando -f.

So the question is, what's going on here? why I'm getting this, if the package was not installed? How do I remove this?

EDIT: changed language into english, used the answer proposition of solution and I get this:

sudo apt-get -f install

[sudo] password for administrador:

Reading package lists... Done

Building dependency tree

Reading state information... Done

Correcting dependencies... Done

The following extra packages will be installed:

  apt-show-versions libapt-pkg-perl libauthen-pam-perl libio-pty-perl

  libnet-ssleay-perl

The following NEW packages will be installed

  apt-show-versions libapt-pkg-perl libauthen-pam-perl libio-pty-perl

  libnet-ssleay-perl

0 to upgrade, 5 to newly install, 0 to remove and 3 not to upgrade.

1 not fully installed or removed.

Need to get 427 kB of archives.

After this operation, 1,734 kB of additional disk space will be used.

Do you want to continue? [Y/n]

Ok, I know this was caused by webmin unfinished install, so the question then is, how do I uninstall an unfinished installation of webmin, or how do I remove this dependencies if I don't want to install webmin (aka, using the "apt-get -f install")?

Thanks in advance.

PD: this server was restarted several times after the "try" of install webmin. Also, don't know if this is needed info but I'm using ubuntu server 14.04.5

sudo dpkg --configure -a

sudo apt-get autoremove

sudo apt-get clean

sudo apt-get update

If it doesnt work

sudo apt-get autoremove <package name>

Or
sudo apt purge

Try this

I had the same issue.

The "universe" repositories were commented out in my /etc/apt/sources.list

To fix:

Edit and remove the "#" in the front of these lines:

deb http://us.archive.ubuntu.com/ubuntu/ <distro> universe

deb-src http://us.archive.ubuntu.com/ubuntu/ <distro> universe

deb http://us.archive.ubuntu.com/ubuntu/ <distro>-updates universe

deb-src http://us.archive.ubuntu.com/ubuntu/ <distro>-updates universe

Then:

apt update

apt full-upgrade -y

gdebi <package name> or apt install <package name>
