Cleaning up Ubuntu 14.10,14.04,13.10 system

We have already discussed Cleaning up a Ubuntu GNU/Linux system and this tutorial is updated with new ubuntu versions and more tools added.

If you want to clean your ubuntu machine you need to follow these simple steps to remove all unnecessary junk files.

Remove partial packages

This is yet another built-in feature, but this time it is not used in Synaptic Package Manager. It is used in the Terminal. Now, in the Terminal, key in the following command

sudo apt-get autoclean

Then enact the package clean command. What this commnad does is to clean remove .deb packages that apt caches when you install/update programs. To use the clean command type the following in a terminal window:

sudo apt-get clean

You can then use the autoremove command. What the autoremove command does is to remove packages installed as dependencies after the original package is removed from the system. To use autoremove tye the following in a terminal window:

sudo apt-get autoremove

Remove unnecessary locale data

For this we need to install localepurge.Automagically remove unnecessary locale data.This is just a simple script to recover diskspace wasted for unneeded locale files and localized man pages. It will automagically be invoked upon completion of any apt installation run.

Install localepurge in Ubuntu

sudo apt-get install localepurge

After installing anything with apt-get install, localepurge will remove all translation files and translated man pages in languages you cannot read.

If you want to configure localepurge you need to edit /etc/locale.nopurge

This can save you several megabytes of disk space, depending on the packages you have installed.

Example:-

I am trying to install dicus using apt-get

sudo apt-get install discus

after end of this installation you can see something like below

localepurge: Disk space freed in /usr/share/locale: 41860K

Remove "orphaned" packages

If you want to remove orphaned packages you need to install deborphan package.

Install deborphan in Ubuntu

sudo apt-get install deborphan

Using deborphan

Open Your terminal and enter the following command

sudo deborphan | xargs sudo apt-get -y remove --purge

Remove "orphaned" packages Using GtkOrphan

GtkOrphan (a Perl/Gtk2 application for debian systems) is a graphical tool which analyzes the status of your installations, looking for orphaned libraries. It implements a GUI front-end for deborphan, adding the package-removal capability.

Install GtkOrphan in Ubuntu

Open the terminal and run the following command

sudo apt-get install gtkorphan

Remove Orphan packages using Wajig

simplified Debian package management front end.Wajig is a single commandline wrapper around apt, apt-cache, dpkg,/etc/init.d scripts and more, intended to be easy to use and providing extensive documentation for all of its functions.

With a suitable sudo configuration, most (if not all) package installation as well as creation tasks can be done from a user shell. Wajig is also suitable for general system administration.A Gnome GUI command ‘gjig' is also included in the package.

Install Wajig in Ubuntu

Open the terminal and run the following command

sudo apt-get install wajig

Debfoster --- Keep track of what you did install

debfoster maintains a list of installed packages that were explicitly requested rather than installed as a dependency. Arguments are entirely optional, debfoster can be invoked per se after each run of dpkg and/or apt-get.

Alternatively you can use debfoster to install and remove packages by specifying the packages on the command line. Packages suffixed with a --- are removed while packages without a suffix are installed.

If a new package is encountered or if debfoster notices that a package that used to be a dependency is now an orphan, it will ask you what to do with it. If you decide to keep it, debfoster will just take note and continue. If you decide that this package is not interesting enough it will be removed as soon as debfoster is done asking questions. If your choices cause other packages to become orphaned more questions will ensue.

Install debfoster in Ubuntu

Open the terminal and run the following command

sudo apt-get install debfoster

Using debfoster

to create the initial keepers file use the following command

sudo debfoster -q

you can always edit the file /var/lib/debfosterkeepers which defines the packages you want to remain on your system.

to edit the keepers file type

sudo vi /var/lib/debfoster/keepers

To force debfoster to remove all packages that aren't listed in this list or dependencies of packages that are listed in this list.It will also add all packages in this list that aren't installed. So it makes your system comply with this list. Do this

sudo debfoster -f

To keep track of what you installed additionally do once in a while :

sudo debfoster

xdiskusage -- Check where the space on your hard drive goes

Displays a graphic of your disk usage with du.xdiskusage is a user-friendly program to show you what is using up all your disk space. It is based on the design of the "xdu" program written by Phillip C. Dykstra. Changes have been made so it runs "du" for you, and can display the free space left on the disk, and produce a PostScript version of the display.xdiskusage is nice if you want to easily see where the space on your hard drive goes.

Bleachbit

  1. youker-Assistant is the best application for cleaning up Ubuntu system which is shockingly not mentioned here.I tried debfoster given here and could not figure out what am doing and what is happening despite following every bit given here.All the above advise is of no help.Users will need an application like youker which is so simple like a windows top rated cleaning software and ease of operation with many things bundled in one.Unless applications like this are known and popularized it is difficult for new users to look at Ubantu. Of course youker is saying still under development.Am right now new user on Ubantu, nervously used youker and wondered with the huge amount of cleaning it did and doubted whether my system will be ok or not.But am so happy to see that all is OK and perfect.Mine is new Dell Inspiron 15 5000 series 5558 with i3, 1tb,6gb and Ubuntu 14.04

  2. Thanks for the nice article. Instructions are clear and purposes are well explained. Very helpful. Some articles suggest not to use bleach bit and Ubuntu tweak. Why?
    Thanks
