Giver is an application that allows you to easily share files with other people on your network. It automatically detects other Giver users on your network and lets you send and receive files with a click. Unfortunately, Giver stopped working under both Ubuntu 11.04 and 11.10, so here is how to get it working again.
1. For both Ubuntu 12.04, 11.10 and 11.04: The first issue with Giver is a missing .so file that prevents it from working. This can be fixed by installing libx11-dev
sudo apt-get install libx11-dev
2. For Ubuntu 12.04 and 11.10 only: besides the above issue, there's another issue that prevents Giver from working (it occurs for all applications that still use Mono runtime 2.0 instead of 4.0). To fix this, run the command below:
gksu gedit /usr/share/applications/giver.desktop
And under "Exec", replace "giver" with the following:
/usr/bin/mono --runtime=v4.0 /usr/lib/giver/Giver.exe
Save the file and Giver should now work.
Oh, and since Giver is not available in the Ubuntu 11.10 Oneiric Ocelot or 12.04 Precise Pangolin repositories, you can download the .deb from here.
