Download a Package Without Installing

Use the download option to download any given package without installing it. For example, the following

command will only download the “nethogs” package to the current working directory.

moxa@Moxa:~$ sudo apt-get download wget

Check a Package’s Change Log

The changelog flag downloads a package’s change log and displays the version information of the package

that is installed:

moxa@Moxa:~$ sudo apt-get changelog wget

Check Broken Dependencies

The check command is a diagnostic tool used to update a package cache and check for broken dependencies.

moxa@Moxa:~$ sudo apt-get check

Search and Build Dependencies

The build-dep command searches the local repositories in the system and installs the build dependencies for

a package. If the package does not exist in the local repository, it will return an error code.

moxa@Moxa:~$ sudo apt-get build-dep wget

Auto Clean Apt-Get Cache

The autoclean command deletes all .deb files from /var/cache/apt/archives to free up a significant

volume of disk space:

moxa@Moxa:~$ sudo apt-get autoclean

Auto Remove Installed Packages

The autoremove sub command is used to automatically remove packages that were installed to satisfy

dependencies on other packages, but are no longer required. For example, the following command will remove

the installed package wget, including all its dependent packages:

moxa@Moxa:~$ sudo apt-get autoremove wget
