How to Install MATE Desktop Environment in Ubuntu 12.10

Removing a PPA from software-sources

How to remove a PPA in Ubuntu 12.04/12.10

PPA(Personal Package Archive) is great  for  installing new and cool apps/utils in Ubuntu or similar GNU/Linux distro such as Linux Mint etc. Due to PPA, publishing and distributing apps has become very easy.

Sometimes you may want to remove an application installed using PPA (may be because some sort of conflict occurred between the app installed from official repository and PPA) or may be you added a wrong PPA address and you get some error messages (on terminal, e.g file not found) or update manager is not working properly due to broken PPA etc. In that case, just follow any of the method (to uninstall the ppa) –

Removing a PPA address in Ubuntu 12.04/12.10/.. Linux Mint / similar_distro

Method #1. remove the ppa file(*.list) from  /etc/apt/sources.list.d directory. Open a terminal and execute the command

ls /etc/apt/sources.list.d
ppa_1.list       ppa_2.list       ....  ppa_no_longer_required.list

sudo rm /etc/apt/sources.list.d/ppa_no_longer_required.list

 

Method #2. If the ppa contains a newer version of standard package, then you have to use the command –

sudo ppa-purge <ppa_address>

ppa_address will be in the format of ppa:name/sub_directory (if required)

(so that it fall back to old version of the application as if there was no PPA)

Removing a PPA from software-sources

Method #3. From Software Sources – go to Ubuntu Software Center -> software sources -> other software (In Ubuntu 12.10, you can directly go to software sources) and uncheck the ppa you want to remove.

Finally, update the package cache, using the command –

sudo apt-get update

Markdown editor for Ubuntu 12.04/12.10

Markdown is a lightweight markup language. Using markdown, you can write content in a simple and easy to read plain text, and finally, it will generate the equivalent html(valid XHTML or html) for publishing on web. So, it’s certainly more human friendly for web writers, specifically if you are looking for a simple and efficient replacement for WYSIWYG editor.

Editing Markdown with ReText

Ubuntu 12.04/12.10 comes with a plain text editor called – gedit. gedit is good text editor, you can also use it as a markdown editor (it will highlight the syntax well) but the problem is that – you can not preview your document. You can’t export your markdown text to html or pdf or any format. You will have to manually export it using the command line utility and if anything goes wrong, then again – edit -> save -> export. That’s not very efficient.

So a dedicated a Markdown editor is obviously, a better choice. There are many markdown editors available for Ubuntu 12.04/12.10 such as ReText, Uberwriter etc but ReText is the best one!

ReText – Markdown Editor for Ubuntu/Linux

ReText is a text editor for markdown and reStructuredText. It’s a simple and easy to use editor but it has lot of cool features. It’s written in Python, so you can run it everywhere, not just in Ubuntu or Linux Mint (check recommended links section for official page where you can download it for other platforms).
