Hello, After complaints from users, I have removed all the -0.90 (faulty) packages from PPA. I am starting a fresh with the newer versions of Sugar Packages. * Previously I started with presence service but found to be stuck with Dependency tree. Now I am following the method mentioned below: (The method is based on a bit of trial and errors to actually get all the packages in order). - Started from the package on the root of Dependency tree. (Sugar, available at PPA). - Downloaded the source package from <a href="http://download.sugarlabs.org">download.sugarlabs.org</a> . (easy step) - Cloned git repository of Jonas' Sugar debian package: <a href="http://git.debian.org/?p=collab-maint/sugar.git">http://git.debian.org/?p=collab-maint/sugar.git</a> (easy step) -- I needed a proper debian folder (and not to forget the updated one). - Copied the debian folder from repo to the extracted source tarball. (easy step) - Changed the debian/control and <a href="http://control.in">control.in</a> files to add the 'Conflicts' and 'Replaces' fields. (new step) -- here is the paste of what I changed: <a href="http://paste.ubuntu.com/523095/">http://paste.ubuntu.com/523095/</a> -- NOTE: Check carefully for 'Conflicts' and 'Replaces' for all packages. - Once done with above, updated the debian/changelog (using dch -i) (very easy) -- here is the paste. - Built that package with 'debuild' command. Renamed .orig tarballs wherever applicable. - Checked all the packages for 'Conflicts'. If found, removed the package from the system and then continued installing again. - Unmet Dependencies found. (sugar-base, sugar-toolkit, etc) Repeated process for the Dependencies. I think we are getting close to the solution. The only part we need to be careful of is the changelog, control and <a href="http://control.in">control.in</a> files. We also need a test PPA for full testing of the packages. Rest I think is going well with the issue. Regards, Dipankar
