Ubuntu-> Package Management->aptitude

Like Apt-get, Aptitude is the most powerful package management tool in Debian and its derivative systems. Unlike Apt-get, aptitude is better at dealing with dependency issues. For example, when aptitude deletes a package, it also deletes the packages it depends on. This way, the system will not be left with useless packets, the whole system is cleaner.

For example: If you use the sudo apt-get install Libncurses5-dev command, the following problems may occur:
"The following packages have dependencies that are not satisfied:
Libncurses5-dev: dependent: libncurses5 (= 5.6+20071124-1UBUNTU2) But 5.7+20090207-1UBUNTU1 is going to be installed
E: Unable to install the package "

Can be replaced with aptitude install can be installed successfully.

It's important to note that Apt-get and aptitude don't mix, because they don't know what's going on in between.

Here are some common aptitude commands.

Command	Role
Aptitude Update	Update the list of available packages
Aptitude Upgrade	Upgrade the available packages
Aptitude Dist-upgrade	Upgrade your system to a new release
Aptitude Install Pkgname	Install package
Aptitude Remove Pkgname	Delete Package
Aptitude Purge Pkgname	To delete a package and its configuration files
Aptitude search String	Search Packages
Aptitude Show Pkgname	Display Package Details
Aptitude Clean	To delete a downloaded package file
Aptitude AutoClean	Delete Expired package files only

Of course, you can also use aptitude in text interface mode.
