    Synaptic Package Manager Complete Removal Function

    Does the complete removal function in Synaptic Package Manager also remove any dependencies that the main program called in?

    Thanks.

    No, it does not remove dependencies (you have to do that manually). The complete removal removes the program's configuration files. This is similar to:

    Code:
    sudo apt-get remove --purge application-name
    replacing application-name with the name of the app (--purge removes the config files).

    Re: Synaptic Package Manager Complete Removal Function

    Is there a way to find out which extra dependencies the program called in (not the ones that are already on my system)? I tried searching that program again in the package manger and when the installation window comes up no dependencies are listed. I also tried checking the properties of that program that clicking on the dependencies tab and it listed a lot of dependencies but it doesn't have any date (installed date) associated with it so I'm clueless as to what to remove because I don't want to remove dependencies existed there previously before that program called it. By the way the program i'm talking about here is midori.

    Thanks

    Re: Synaptic Package Manager Complete Removal Function

    you can remove dependencies that are no longer needed by other programs:

    from the man page of apt-get:
    autoremove
    autoremove is used to remove packages that were automatically
    installed to satisfy dependencies for other packages and are now no
    longer needed.
    autoremove is an option with apt-get:

    sudo apt-get autoremove

    Also can be done with Synaptic. Click the Status button, and choose "installed (auto removable)". Those can be selected and marked for removal.

    Hi I looked around the web about the command sudo apt-get autoremove and I see some people had issues after doing it? Issues where they can't log in and where system files being deleted? So i'm a bit scared to try that command. Did you have any experience with that command?

    Only a few times. You can run a simulation which will show you what would happen:

    Run autoremove in simulation mode:

    Code:
    apt-get -s autoremove
    no sudo is necessary with a simulation (-s option). It will tell you what packages would be removed. If you decide to go ahead, run

    Code:
    sudo apt-get autoremove

    Hey thanks so much for that -s option! Oh man that would come handy in so many situations.
    I tried it and it only showed three dependencies so I'm not even gonna bother with removing anything.

    If you are concerned, I would say that since we have so much disk space now, leaving the dependencies installed has little downside. Generally, they are not big files anyway.

    I was concerned but now that i know it's only three I don't mind. I go crazy when things are cluttered and there're things that I don't need any more. Real world and in the virtual world.
    I'll just leave them installed. I have 123GB left anyways.
    Thanks for your time.

    I've been using sudo apt-get autoremove since I started using Ubuntu with 11.04. I haven't noticed any ill-effect.

    One request: when you post something like "I see some people had issues after doing it", please do share a few links if possible.
    Shortened urls: See point #11 here. And clicking on them could be risky.
