Here's the deb package:
gecko-dotnet_0.61-4.deb (1.2 MiB)
Instructions:
*Make sure you have your USB Gecko connected to your computer when you install this.
1. Download the file to your Desktop (or another location), then double click the deb file (this should launch GDebi).
2. Review any details you may want before installing, then click 'Install Package' and type in your password.
3. Click the "show terminal button" on the installation dialog (Progress bar, etc.), click in the terminal screen, read the statement and then press enter. Failure to do this step will leave GDebi idle (it won't install Gecko dotNET).
4. Sit back for a minute or two for the install to finish.
OR you can install using the terminal. Here's a set of commands that should work:
cd $HOME/Desktop
wget -c "http://ubuntuone.com/p/4My/" -O gecko-dotnet_0.61-4.deb
sudo dpkg -i gecko-dotnet_0.61-4.deb
Just press enter when it asks, then it should install just as fine as GDebi would.
When the install is complete, you can find the menu entry in Applications -> Programming (under the name of "Gecko dotNET") or by running the command "gecko-dotnet".
All config files should be placed in "/home/[yourusername]/.gecko-dotnet".
This should hopefully work without problems; let me know if it doesn't (the only issue might occur with dependencies). Also, this was tested on Ubuntu 10.04 Lucid Lynx only, and will probably only work on this version (due to older versions of libftdi that were shipped in previous versions).
Enjoy!
EDIT: I just realized I forgot something important; run this command in a terminal:
sudo ln -s /usr/lib/libftdi.so.1 /usr/lib/libftdi.so
This creates a necessary symbolic link so that Gecko dotNET can access libftdi (otherwise GDN is useless). I'll try to include this in the next revision of the deb package.
