Without following the instructions below, you would receive an error in the .log file similar to below.

!MESSAGE Unable to find feature.xml in directory: /home/homdir/Aptana-Studio/features/com.aptana.ide.feature.professional_1.2.4.022837_200903111829.jar

Ubuntu 8.10 specific install instructions:

Aptana needs xulrunner 1.8 and sun-java installed to work.

Command: sudo apt-get install xulrunner

Command: sudo apt-get install sun-java-bin

I found launching Aptana from a bash script was the easiest work around.

Command: cd ~/

Command: nano ~/aptana.sh

copy and paste the below into your terminal window.

#!/bin/sh
MOZILLA_FIVE_HOME=/usr/lib/xulrunner
if [ $LD_LIBRARY_PATH ]; then
LD_LIBRARY_PATH=$MOZILLA_FIVE_HOME:$LD_LIBRARY_PATH
else
LD_LIBRARY_PATH=$MOZILLA_FIVE_HOME
fi
export MOZILLA_FIVE_HOME LD_LIBRARY_PATH
~/Aptana-Studio/AptanaStudio -os linux /usr/lib/jvm/java-6-sun/jre/bin/java

NOTE: change the path ~/Aptana-Studio/ to the same directory that you extracted Aptana to from the downoaded package.

Launch Aptana

Command: ./aptana.sh
