Yesterday I upgraded my Ubuntu 9.10 to the new Ubuntu 10.04 on my laptop DELL Vostro 1310.
The new version of Ubuntu is pretty and it looks like you are using a mobile phone.
So let me share with you guys how to install Sun JDK 1.6 on Ubuntu 10.04 because it is not just type sudo apt-get install sun-java6-jdk on command line.
Below you can see the message you will receive after you try to install JDK 1.6 on Ubuntu 10.04 using the common way.
"Package sun-java6-jdk is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package sun-java6-jdk has no installation candidate"
Just follow the commands below:
What I did to solve this problem was to add a new source
sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
After that just do the normal way.
sudo apt-get update sudo apt-get install sun-java6-jdk
That's it. It worked for me.
