How to install Texmaker 4.0.1?

I'm new to LaTeX, but want to get started for real; settled for Texmaker; now checked the version (and changelog) and noticed a discrepancy between what I've got installed (3.4) and what's been released (4.0.1) -- just a few days ago.

I found an outdated PPA, but nothing else so far. So far, I've either installed things through Ubuntu or via a PPA, but hardly ever downloaded from a dev website, let alone compiled stuff from source.

  1. Does anyone know of a PPA or an official Ubuntu way of upgrading to the latest release of Texmaker?
  2. Are there any reasons I should not go ahead and simply download Ubuntu 12.04 i386 package : texmaker_ubuntu_12.04_4.0.1_i386.deb (Qt4) ?

Please provide some guidance or a link to a good discussion/explanation on what to do a with a deb-file... i.e.,

  • How does it differ from directly installing through Ubuntu Software Center;
  • What needs to be considered / taken care of / maintained;
  • Why should one (generally) avoid a "manual" deb-installation (especially if one does trust the source)?

Solution 1:

The Software Center didn't have the latest texmaker as 4 days ago when I installed. I downloaded and installed the amd64 version downloaded texmaker's website. I followed the instructions for Linux; that is, remove all previous version and install.

  1. Download the most recent version (be sure to choose the correct version for your system: 32 or 64 bit): http://www.xm1math.net/texmaker/download.html
  2. Open a terminal (Ctrl+Alt+T) and enter sudo apt-get purge texmaker to remove any previously installed version
  3. Assuming the new version you just downloaded is in the Downloads folder, issue the following command in a terminal: sudo dpkg -i ~/Downloads/texmaker_ubuntu_*.deb
