If your linux distro is based on debian, e.g. ububtu, linux mint etc... execute this command: wget -q -O - https://sourceforge.net/projects/skylendar/files/installskylendar.sh | bash Press y when asked if you want to download the archive. If not debian, you have to compile and install skylendar yourself, unless you find out someone else who can help you. Try in the forums of your distro.
