Install 1.0.5 on Ubuntu 12.10

Can someone point me in the right direction please, I'm feeling a bit thick today.

Up to now I have been using IDE 1.0.1 on Ubuntu 12.10. I installed this from the Ubuntu Software Centre, which also now offers 1.0.3, but fails to install it! But that's pretty out-of-date anyway, so I'd like to try 1.0.5.

I have downloaded arduino-1.0.5-linux64.tgz from the Arduino site download pages. But what do I do with it?

The wiki says:

After the installing the stable version, development versions or nightly builds can be downloaded from the arduino.cc servers, unpacked anywhere, they run out of the box

... which doesn't help much! Surely I need to copy/overwrite something with the contents of the .tgz file?

There is a file called "arduino" of type "unknown". Looks like a shell script... Is this what I must run?

Thanks!

Unpack the downloaded Linux IDE v1.0.5 from the download section of the Arduino website, not the Ubuntu repository. In the unpacked directory (arduino-1.0.5) there is an arduino script. Run it. It may ask if you want to open the file or run it. Select "run".

This arduino script is directory dependent, so you can't move it. If you want to run it from the desktop, you must create a link and move the link to the desktop.

edit: You can do this with other versions of the IDE also. I have v1.0.1, v1.0.2, v1.0.3, v1.0.4, v1.0.5, and v1.1.5 on my Ubuntu box.

Thanks Tim,

Is there any way I can install 1.0.5 over the top of 1.0.1, as though it had been installed with Ubuntu S/W centre?

Is there any channel for us to request Canonical to upgrade their repositories?

I have not found a way to install the downloaded version to replace the repository version. I gave it a half-hearted try at first, then realized I wanted all the IDE versions available for testing so I could determine if it was ok to start using a new IDE version.

I did some upgrade stuff for Ubuntu, but it was not worthwhile in the end. The downloaded version from the Arduino site uses all its own gcc compiler and library stuff, so it doesn't require any Ubuntu upgrades to work right out of the box.
