    Re: How uninstall softwares included in LUbuntu ?

    Look, Ubuntu is Linux for humans and that include non geeks, instead of scratching your head over apt-get, apt, purge and all these business that takes a few posts to explain, Lubuntu comes with gui package manager. Search for synaptic, find the application you want to remove, right click and choose remove or completely remove (that is the same as purge) and it will show you what other packages it will remove and so you can decide whether to go ahead or not. If it removes a lot of other stuffs then you'd better keep it because something it removes maybe vital to the system. That's it.
    Sorry, it is just nonsense to tell a new user to read man apt-get just to remove some packages.


    Edited: or muon, which is basically the same as synaptic. Lubuntu used to come with synaptic but maybe the qt version comes with muon, so use that.

    I use 3G connection and not has the MODEM driver installed that is the because of my choice to backup all packages.

    @ActionParsnip
    "Each package is installed with dpkg. This is abstracted with ap(-get) which manages deps for you. Each package can be uninstalled using the dpkg command or apt(-get) command. Each package doesn't need its own uninstaller like in Windows. Each package knows it's contents so when you tell the system to uinstall a package it removes those files and runs any post uninstall sripts."

    What ? I use Windows and unhappily has softwares that need to use unninstallers to remove all files. Linux not need unninstallers for any software installed ?

    "Please note that uninstalling an application does NOT remove the per-user configuration in each user's $HOME folder."
    In Linux any software will allways use $HOME to configuration ? If yes allways is an folder with the name of software ?

    Packages contain information about all the programs and settings they will use. The package manager understands this and that is who we both install and remove programs.

    There are multiple types of settings for most packages:
    • system-wide settings, usually stored in /etc/ somewhere.
    • per-userid settings, always stored in $HOME somewhere. Each userid has a different $HOME.


    When a package is
    • removed through the package manager, it removes the programs and libraries for that package. It leaves the system-wide and per-userid settings.
    • purged through the package manager, it removes the programs, libraries, AND system-wide settings for that package. It leaves the per-userid settings.


    The package manager isn't important. They each have these capabilities. 1 warning. Do not use dpkg directly to install or remove packages. Only use the package managers, so dependencies are addressed.

    Examples of package managers: synaptic, "software center", apt, apt-get, aptitude, and I guess muon. Each different desktop environment flavor can have their own, so there may be more. I tend to use apt and apt-get. They have slightly different capabilities which are handy, but end-users can use GUIs and accomplish the same things, just slower (the time to launch, search, click, click, click, ok).

    Simple tools have no config files in HOME, but many big applications have. They are usually in $HOME/.appname or in $HOME/.config/appname or something like that. Note that files/directories with a name starting with a dot are hidden files/directories. File management tools won't show them, unless asked for.

    About the only case where you have to run dpkg is when you want to fix the package manager if it's so far broken that apt no longer works. In all other cases apt will call dpkg for you.
