E: Unable to locate package ros-kinetic-desktop-full on Ubuntu 16.04

Question

I know that there are already several questions similar to this, but none of its solutions worked for me. Hence, after a lot of web searching and trying out different stuff, I simply decided to open a Stack Overflow question myself.

Basically, I had ROS Kinetic working on my Ubuntu 16.04 machine and it suddenly started giving me several errors when I tried to build my catkin workspace. After trying several stuff, I decided to uninstall ROS with sudo apt-get remove ros-* and install it again, according to the tutorial http://wiki.ros.org/kinetic/Installation/Ubuntu .

I leave below the full execution of the installation commands:

I already tried using curl and the different links they suggest on the tutorial to setup my keys, but the end result was the same. If I try sudo apt-get install ros-desktop-full , I get:

tomas@tomas-TOSHIBA:~ $ sudo apt-get install ros-desktop-full

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.
 ros-desktop-full : Depends: ros-desktop but it is not going to be installed
                    Depends: ros-perception but it is not going to be installed
                    Depends: ros-simulators but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Running sudo aptitude install ros-desktop-full also did not work. If I execute sudo apt-get install ros-desktop , it says that ros-desktop has unmet dependencies. If I try to install those dependencies, they also have unmet dependencies.

Would really appreciate if anyone could help me. Thanks!

For all those suffering from the same problem, I was not able to solve it and ended up reinstalling Ubuntu on my computer. After this, everything worked correctly.

My advice would be to just reinstall Ubuntu right away, I would have lost less time if I had done it immediately.
