The version of fldigi that’s built for Ubuntu 9.10 is a bit out of date. Luckily, the Berlios repository has a more recent version, and you can install that.
The instructions are here. In short form (specific to Ubuntu 9.10):
- Edit /etc/apt/sources.list and add the following lines:
# Berlios repository for updated FLDigi deb http://download2.berlios.de/pub/fldigi/binaries karmic main
- Get the key for fldigi
sudo apt-key adv --recv-keys --keyserver http://fldigi.berlios.de/binaries/fldigi-pkg-key.asc 8E7306F5
- Install fldigi
sudo aptitude update; sudo aptitude install fldigi
