After you have downloaded the disk image file, double click it and a folder window opens.

Open a terminal window and make the installer executable with:
> chmod +x multibitclassic-0.4.19-linux.jar
Run the installer with:
> java -jar multibitclassic-0.4.19-linux.jar
Follow the instructions in the installer.
After installation, you will have a shortcut to start MultiBitClassic in your "Applications | Other" menu.
Notes:
If you get an error like "No command 'java' found" or the installer window does not appear you probably need to install an up-to-date version of Java. See the section 'How to install Java on Linux' below.
If you see an error "***.desktop (No such file or directory)" this is a glitch in installing the MultiBitClassic shortcuts. If you run the installer again with the same settings it normally fixes it.
If no MultiBitClassic shortcut is created, you can run MultiBitClassic manually as follows:
1) open a terminal window and 'cd' to your installation directory.
2) type:
> java -jar multibitclassic-exe.jar
To install Java on a recent copy of Ubuntu open a terminal window and type:
> sudo apt-get install openjdk-7-jdk
You will be prompted for your system password and then it will install the required packages
If you are running an older version of Ubuntu (e.g. something like Ubuntu 10.4 LTS) you will have to use the following:
> sudo apt-get install openjdk-6-jdk
For RedHat / CentOS the installation command is:
> yum install java
