After upgrading to 16.04 I tried to use "sudo aptitude update" at the command line and got the error that the command was not found. What do I need to do to be able to use it again?

Hot tip: You don't need 'apt-get' in 16.04, only 'apt'. Example:

sudo apt install aptitude

You can always use

sudo apt-get update
sudo apt-get upgrade

to update your system, but if you like using aptitude

sudo apt-get install aptitude

should install aptitude.


Seems https://launchpad.net/ubuntu/xenial/+source/aptitude is available.

Just open your terminal and type sudo apt-get install aptitude

Then try again.

Thank you.
