3 Update The System
Now it's time to check for updates and install them. This is done using the Update Manager (Applications > System > Update Manager):
The Update Manager tells you which updates are available. If some of them need dependencies it tells you so - in that case, mark them for installation by clicking on Mark Updates:
Confirm with OK:
Finally, click on Install Updates:
Enter your password for authentication:
The updates are now being downloaded and installed:
If a new kernel was amongst the updates, a system restart is required to make the changes effective.
To perform a restart open the menu and click on Leave > Restart > Restart Computer:
The system is now up-to-date.
4 Flash Player And Java
If you have checked the Install this third-party software checkbox during installation Flash Player should already be installed on the system but Java has to be installed manually.
To check this, the simplest way is to install Firefox. Open the menu and find the Firefox installer. Click on Install once you start it:
Type in your password for authentication:
Firefox will be installed afterwards...
Once Forefox starts, type about:plugins in the address bar. Firefox will then list all installed plugins, and it should list the Flash Player (version 11.2 r202) plugins among them.
