Your mono-free photo manager for Gnome and non, Solang (alternative to F-Spot)) is now included in Ubuntu 9.10 repositories. Karmic Koala users can now install Solang v0.3 from the command-line with sudo apt-get install solang or via the “Ubuntu Software Center”.
Likewise Gnote (a mono-free alternative to Tomboy) also makes it into the Karmic Koala repository. You can get it installed with sudo apt-get install gnote or via the “Ubuntu Software Center”; Applications -> Ubuntu Software Center
Canonical does not provide automatic updates for Solang Photo Manger and Gnote, you’ll have to do so manually.
