 ==== Package management ====
-[[https://www.howtogeek.com/63997/how-to-install-programs-in-ubuntu-in-the-command-line/|apt-get tutorial]] if you are more used to Fedora/RedHat ''yum''/''dnf'' and //rpm// packages
+=== How does it work ? ===
-  * Install the **aptitude** package manager: ''apt-get install aptitude''
+  * **Ubuntu applications** are distributed through package files in **//Debian// format** (''.deb'' files) that are found in [[https://help.ubuntu.com/community/Applications#Software_repositories|software repositories]]
-    * [[https://doc.ubuntu-fr.org/aptitude|details]] (fr)
-  * Install the **synaptic** package manager: ''aptitude install synaptic''
-    * [[https://doc.ubuntu-fr.org/synaptic|details]] (fr)
+  * High level package management tools such as ''aptitude'' or ''synaptic'' rely on ''apt'' which, itself, relies on ''dpkg'' to manage the packages in the system
+    * The ''apt'' tool merges functionality of ''apt-get'' and ''apt-cache'' and by default has a fancier colored output format, making it more pleasant for humans. For usage in scripts or advanced use cases, ''apt-get'' is still preferable or needed
+    * ''apt*'' tools and ''dpkg'' are pre-installed on Ubuntu
+    * [[https://www.debian.org/doc/manuals/debian-faq/pkgtools.en.html#aptitude|aptitude]] can be used on the command-line or through a **text-based interface**
+      * You do not need to have an [[other:x_conf|X server]] running to use ''aptitude'', therefore aptitude can be used in the early stages of a Linux installation, or on a remote Linux computer
+    * [[https://www.debian.org/doc/manuals/debian-faq/pkgtools.en.html#synaptic|synaptic]] is a graphical package manager
+      * You need to have an [[other:x_conf|X server]] running in order to use it
-=== Useful commands ===
+  * All the details can be found in [[https://www.debian.org/doc/manuals/debian-faq/pkgtools.en.html|The Debian package management tools]]
+=== What about snap ? ===
+FIXME [[https://snapcraft.io/docs|Snap documentation]]
+=== Installing extra package managers ===
+  * Installation: ''sudo apt install aptitude synaptic''
+    * It may install lots of dependencies, but that's to be expected if no other packages have been installed yet\\ <code>$ sudo apt install aptitude synaptic
