I agree that someone should fix the standard repositories. Unfortunately with Maemo5 out the people who have access and know how to do this have probably lost interest in Maemo4 repositories.

To install rsync:

1. Go to Applications --> Settings --> Applications manager.

2. In Application manager, from the top-left drop-down menu select Tools --> Application catalog... .

3. Click the New button, and add the new catalog as follows:

Catalog name: Extras-devel
Web address: http://repository.maemo.org/extras-devel
Distribution: Diablo (unless you're still using Chinook)
Components: free non-free

Make sure the "Disabled" box is NOT checked.

4. Click OK.

5. Highlight the Extras-devel entry and click Edit; inspect your work. When you're satisfied click OK again.

6. Click Close; the Application manager will download new package lists ("updates") for all catalogs that are not disabled.

7. Click on Browse installable applications --> All. Scroll down to rsync. Highlight it and click Install.

8. When all that is completed go back and install grsync. It's a gtk+ frontend for the command-line rsync.
