ubuntuforums members Tutorials

K.Mandla (here and there) has been reviewing and collecting tutorials from the ubuntuforums every week. This work is really impressive (both K.Mandla’s and the UF member’s) and is one of the many useful elements a Ubuntu newcomer may find useful.
Please visit the Tutorial of the Week thread, and feel free to suggest UF Tutorials in this thread. Thanks!

Edit /etc/sudoers with gedit in Ubuntu Hardy Heron

I came across a UF thread that p_quarles pointed at us in the Staff area. Thanks p_quarles :).
The classic:

export EDITOR=gedit && sudo visudo

will open /etc/sudoers with visudo, which does not behave like nano any more. I’m not a vi fan, please accept my apologies, Ive said it. I’m a nano fan :)
But I understand some users feel more comfortable with gedit or other GUI text editors.

The way to go now is:

export EDITOR=gedit && sudo -E visudo

where the -E option preserves the user environment variables.

.7z archives on Ubuntu hardy

I just stumbled upon this one yesterday. .7z archives were given to me but impossible to extract them on a basic hardy install. A little googling led to p7zip. The package is in the universe repositories. Just install it, and there you go, compress and extract in 7-zip format :)

Medibuntu: non-free-codecs for hardy

Due to the interest to my previous post on gutsy, here is the procedure to install non-free-codecs on hardy:

  • Add the Medibuntu repositories to your sources.list:
    ## Medibuntu.
    deb http://packages.medibuntu.org/ hardy free non-free
  • Add the key to your keyring, reload the sources.list file and install the package:

    wget -q http://packages.medibuntu.org/medibuntu-key.gpg -O- | sudo apt-key add - && sudo apt-get update
    sudo apt-get install non-free-codecs

You need to add the key if you got to this article searching for the following error:

W: GPG error: http://packages.medibuntu.org hardy Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 2EBC26B60C5A2783

Here is the package description for the *codecs from Medibuntu:

bapoumba@scorpio:~$ sudo aptitude show non-free-codecs
Package: non-free-codecs

State: installed
Automatically installed: yes
Version: 1.1

Section: non-free/metapackages

 (w32codecs for i386, w64codecs for amd64 and ppc-codecs for powerpc systems). 

 It can be safely removed.
