Error when trying to install a few packages on ubuntu

Question

I've installed a few packages and got the following message

The package system is broken If you are using third party repositories then disable them, since they are a common source of problems. Now run the following command in a terminal: apt-get install -f

I tried executing apt-get install -f but it does nothing.

Answer 1

Try executing the following commands and try installing them again:

sudo apt-get clean
sudo apt-get autoremove
sudo apt-get update
sudo apt-get upgrade
sudo apt-get -f install
