How to manage sofware

Being based on Debian, AIMS Desktop uses the APT (Advanced Package Tool) to manage software.

Software and its dependencies on AIMS Desktop is managed via packages, for each program on your computer, there is at least one package. Packages can be installed, removed or upgraded.

Here we will show you how to manage software using APT in the command line. APT needs root (administrator) privileges, so you need to run it using the sudo command.

For example, if you want to install the program “meld”, you would use apt install:

$ sudo apt install meld
The following NEW packages will be installed:
Do you want to continue? [Y/n] y

If you would like to remove that package, you can use apt remove:

$ sudo apt remove meld
The following packages will be REMOVED:
Do you want to continue? [Y/n] y

APT’s remove tool plays it safe, and doesn’t automatically remove configuration files or data that may have been created for a package in the system. If you’d like to remove that as well, you can use the purge command. This does not affect any data in your home directory.

$ sudo apt purge meld
The following packages will be REMOVED:
Do you want to continue? [Y/n] y

You will notice an asterisk next to the package name, this indicates that the package will be purged, as apposed to a normal removal.

Security updates and other important software updates happen regularly. To update the list of the available packages for your system, you can run apt update. To install any available upgrades, you can run apt upgrade:

$ sudo apt update
Hit:1 stretch InRelease
Get:1 stretch/updates InRelease [62.9 kB]
$ sudo apt upgrade
The following packages were automatically installed and are no longer required:
  libnfsidmap2 libtirpc1
  Use 'sudo apt autoremove' to remove them.
The following packages will be upgraded:
Do you want to continue? [Y/n] y

In the example above, apt points out that two of the installed packages are no longer required. They might have been installed as dependencies of packages that have been previously removed. To remove them, use the apt autoremove command:

The following packages will be REMOVED:
  libnfsidmap2 libtirpc1
Do you want to continue? [Y/n]


GNOME Software is a graphical front-end that supports APT. It makes it easier to find and install software if you’re still new to the system.

How to use file templates

In previous versions, you could right-click anywhere in the file manager and create a new blank file. In the current version, this has been extended so that you can create any kind of file as a template for a new file. This could be a shell script, document, blank file or any other kind of document that you create on a regular basis.

To do this, all you need to do is place new documents as template files in your Templates directory.


Then, those documents will be available when you right-click in the file browser:
