The application manager has a place to select a web address for the application catalogue.

Application manager:tools:Application catalogue

selecting new gives the following options
web address
distribution (currently set to mistral)
components (currently set to user)
enabled (a checkbox)

Do we know any addresses for this?

Update:
On the maemo.org 2006 site http://maemo.org/maemowiki/ApplicationCatalog2006 FBreader gives a valid address
http://only.mawhrin.net/fbreader/maemo
keep the other values as their defaults.
it worked like a charm. remember to install both packages.

As more sites become available post them here.

oh man... that's SO sweet! It's like apt-get on the 770!
Thanks for the link howard, I'll have to keep on the lookout for more repositories. Sounds like the GPE PIM apps will have a repository soon, but not yet. I'm just keeping the url in my list until it starts working :
http://www.kernelconcepts.de/~fuchs/nokia770/ex_2006/

Apparently it is apt-get. If you open the log after a failed attempt to connect it
says that you may want to run an apt-get update to fix the problem.

Thanks for the link brad.

Here's another one I saw mentioned in another thread:
Repository : http://repository.maemo.org
Distribution : mistral-beta
Component : free

EDIT: This one has gaim!
EDIT2: or... not

and of course don't forget http://gnuite.com:8080/nokia770 for maemo mapper

ok, here's the one with gaim in it, courtesy of Coolty and maemo-hackers.org:
Web address http://maemo-hackers.org/apt
Distribution mistral
Components main

http://maemo.org.br/platform/apt/
Distribution: python
Components: python

Are there any repositories with more than 1 or 2 packages? Whats the use of a package manager, when i have to add a own "link" for every package.

On my Desktop linux (ubuntu) theres a package-manager with hundreds (thousands??) of packages to install. Why is there no repository for N770 with all (at least all FREE) packages.

Maybe a repositorymanager would be a great idea. This could mangae lists of packagelists for the packagemanager.

Because many freelance maemo developers only maintain 1 or 2 applications, and they are the ones creating these repositories. There isn't yet a standardized repository server (that I know of) to which developers can upload their releases.

Maybe Maemo Garage will develop it's own repository, including all applications in the Garage. That would definitely make my life easier.
