Access ALL Apps on the N900

17 12 2009

By default the N900 comes supplied with only 2 Nokia repositories enabled, and the Maemo Extras one disabled.

All you have to do is go into App Manager and select the top menu bar, select Application Catalogues, select the Maemo Extras and untick the box marked Disabled. Refresh the catalogues and you’ll see loads of applications now, all the ones available via

If you’re brave enough you can also enable the Maemo Extras-Devel repository, the is applications in development and are put her for you to test. Think of it as being an alpha tester 😀

To add the Maemo Extras-devel repository just goto App Manager, select the tope menu bar, select Application Catalogues and NEW.

Add the repository using the same info as below, hit save and then refresh the catalogue.

WARNING: Applications in Extras-Devel and Extras-Testing are for experienced users only and may break your device, use at your own risk.

You should really add a big red warning here.

Applications in the Extras-devel repository are alpha versions that haven’t been tested and haven’t been made ready for release. They’re NOT intended for public beta testing. They’re there purely for developers and advanced users to access and carry out the first tests.

These applications can contain serious bugs that can:
– cause your N900 to become slow, unstable and / or crash
– can cause your battery to get drained very quickly
– can completely brick your N900 and can force you to reflash, possibly making you loose some or all of your settings and data in the process

All of these problems have occurred with applications in Extra-devel in the past – these are very real issues you will might encounter by enabling Extras-devel.

I really wouldn’t encourage anybody to enable Extra-devel unless they’re developers or advanced Maemo users who know how to reflash their N900 in case of a big problem and don’t mind loosing their settings and data.

If you want to be a beta tester, then enable Extras-testing instead – that’s where applications intended for public testing go. See here for instructions: Installing applications from Extras-testing is obviously not risk-free either so make sure you read and understand the warnings.

As I have come to understand this between extras and developing repository there is a testing repository. Apps in the developing repository are totally new and some are potentially harmful (they might brick your n900). Where as in the testing repository they are more “buggy” less harmful.

I think you are getting mixed up between “extras-testing” and “extras-devel”

extras-testing is a repository that holds applications waiting to be tested. It is a place where power users can download the latest developer releases, test them out and evaluate them. User backups and predisposition to re-flash your device in case of trouble is assumed.

extras-devel ; Developers upload the newest version of their software to Extras-devel. From there the packages go through an automatic and human Quality Assurance process. This is a repository for developers and regular contributors of specific software projects. If you want to play with extras-devel software you need to be prepared to feel some pain sooner or later.

Please don’t use extras-devel if you don’t know what you are doing. Personally, as a hobby developer, I’ve uploaded all kinds of trash applications there that could easily wreck your device and run down your battery.
However, if you’re adventureous and have fun on the bleeding-edge, enable extras-testing and join the community. by voting apps up or down according to the QA criterias.

Is there a place where inexperienced users can go to learn more about the apps in extras-dev? somewhere with a list of pros and cons of a new app. i’d be willing to try things out if i knew it wouldn’t brick my n900.

Your best bet is to register with and get involved with the community. Most apps old and new are discussed on there and a quick search might help you decide if an app is okay to install. Alternatively follow @gerrymoth on twitter as I test and brick my N900 😀

Extra Devel seems pretty scary… But Extra Devel is the spirit of N900 and it’s what an open source all about. Hopefully all developers won’t just throw some apps that will damage our beloved N900. Cheers. 🙂
