I have linux mint, equivalent to ubuntu 16.04. I changed my graphic card and I uninstall the nvidia drivers to install the amd ones, but I installed drivers for ubuntu 18.04 instead of 16 and now I can't remove it, and I can't install or upgrade anything else.

When I type: # amdgpu-pro-uninstall

noik@noik-mint ~ $ amdgpu-pro-uninstall

Package 'amdgpu-core' is not installed, so not removed
You might want to run 'apt-get -f install' to correct these:

Then I try with: # sudo apt-get -f install

If I type: sudo apt-get purge amd*
Or I type: sudo apt-get autoremove
The same result than amdgpu-pro-uninstall upgrade appears.

What else can I do?

I couldn't solve it with commands, I solve it with Synaptic Package Manager, filtering by broken packages and "mark for complete removal".

There are four simple steps involved in the installation of the AMDGPU-Pro Driver: Download, Extract, Install and Configure. The instructions to perform the installation are intended for an Ubuntu installation of 16.04, and should take less than 10 minutes to complete. Before installing the driver, a quick note on how to check if your system already has AMDGPU-PRO installed. In addition, the recommended best practice is to bring the system up-to-date before starting the driver installation, with:

sudo apt update
sudo apt dist-upgrade
sudo reboot
