Whenever trying to install any software and update manger,

I get an error stating

Package operation failed
The installation or removal of a software package failed

When I run sudo apt-get update I got this result:

conan51xd@conan51xd-Lenovo-B470:~$ sudo apt-get -f install
[sudo] password for conan51xd:
