I want a list of applications which I have installed only using  sudo apt-get install   and nothing else. I came across this post:   but the answer lists all installed packages (including ones which were pre-installed and weren't installed using   sudo apt-get install   ).

I'd like to get a list of packages installed manually by apt or aptitude and be able to find out whether a foobar package was installed manually or automatically. Is there any neat way of doing that from the command line?

I'm trying to find what packages I have installed from a repository using terminal commands.  I found a post somewhere saying I could use aptitude search "?origin (&lt;repository&gt;) ?installed", but I couldn't get it working. I tried searching for a packages that came from ppa:ubuntu-wine/ppa and got nothing with these:  aptitude search "?origin (http://ppa.launchpad.net/ubuntu-wine/ppa/ubuntu/) ?installed" aptitude search "?origin (http://ppa.launchpad.net/ubuntu-wine/ppa/ubuntu/) ?installed" aptitude search "?origin (http://ppa.launchpad.net/ubuntu-wine/ppa/ubuntu/ raring/main) ?installed"   It would be nice if I could get something that works with PPAs.

apt-cache search returns list of available packages. In my case I would like to look at  the list of files that would be installed on my PC in case I install the package usb-creator-gtk.  Something like dpkg-query -L does for an already installed package.   Thanks for help.

I read about the new fancy progress bar which was added to apt 1.0 in  and how to enable it . However on running sudo apt-get update, I did not see the fancy progress bars. On reading the second link again, the solution explicitly requires you to use sudo apt update.  Hence my question is the difference between apt and apt-get. I thought they were one and the same.

Is there any difference between     sudo apt-get purge &lt;package-name&gt;   and    sudo apt-get remove &lt;package-name&gt;     ?  I often see people recommend one or the other.  In other words, what does apt-get purge remove that apt-get remove doesn't?

After doing a man apt-get and cursory Google search it's not clear how I find new programs to install (from the internet) using apt-get (which is amazingly powerful and simple coming from another Linux distro).  I'm using Ubuntu Server 8.04 LTS (an inherited system used for some random work), so no GUI.  Anyone have quick advice here?

I do not want packages to be installed under /. (sudo apt-get install ...).   The reason why I need to do this is that:  My '/' is mounted with my SSD(16GB) and my hard disk(500GB) is mounted at '/home'.   I have already installed my Ubuntu 12.04 on that SSD. There is not much free space under '/' now.

Is there a way to cherry pick packages from a ppa repository you add? That is, to exclude some from updating while including others?  For example, I want just the chromium-browser package from  but not the others. So I don't want my sudo apt-get upgrade to have that ppa's other (besides chromium-browser) packages install over my existing ones, just that one.   I realize this is a license to shoot myself in the foot if I misread dependencies and exclude ones that are needed to ones that I included, but I know for a fact in this case that the other packages are not dependencies for that one.  Is this at all possible? Maybe there is some whitelist/blacklist file or something?

I'm having some difficulties exactly understanding how the the whole update thing work in Ubuntu and good practice for installing software.  I understand I have a  /etc/apt/sources.list file where all my repositories are listed, and that these repositories are queried when I use apt-get update - to later be used with e.g. apt-get upgrade.  This makes perfect sense and I recently installed spotify by adding deb http://repository.spotify.com stable non-free to this "sources" list.    But then I got confused...  When I went to download Google Chrome I merely had to download and grab a .deb file, and Chrome installed with no problem... but I don't see any new entry in /etc/apt/sources.list...  So how does apt-get update know where to query concerning Chrome updates?  Has it somehow been added to one of the already listed repositories in the sources file?  I would like all my installed software to be encompassed by the update function.

When running:  sudo apt-get install quickly   To install quickly I get this output:  Reading package lists... Done Building dependency tree        Reading state information... Done E: Unable to locate package quickly   Why the error and how can I install it then?

Is it possible to get a list of packages that were most recently installed through apt-get?

I am wondering what sudo apt-get update does?  What does it update?

I'm contemplating writing a script that does this:   Goes through each file in /usr/lib Does a dpkg -s search on each file. Reports a list of "orphan" files not belonging to any .deb package.   The idea is that over time, I've installed a lot of make install software and I'd like to get a list of leftover files from manually installed software I've since deleted.

I just typed   sudo apt-get remove python2.6   I didn't realized that this command will uninstall the whole packages from my computer. Is it possible to uninstall the ubuntu without CD. Or how can I fix this big mistake?

I've searched the net for such information and found different command lines, like these ones:  sudo apt-get remove application sudo apt-get remove application*  sudo apt-get remove --purge application sudo apt-get remove --purge application*  sudo apt-get purge application sudo apt-get purge application*   So, what is the correct way? Is it necessary to use that "*"?  After that, I also found these commands:  sudo updatedb sudo locate application sudo rm -rf (file/folder name)
