The java-sun5-* packages are both popular and have been available for quite some time, so I doubt that this is a case of "missing packages": The following forum post was only a few hours old when I had the problem.
http://www.ubuntuforums.org/showthread.php?t=229306#post1337950 Before doing the manual install I tried modifying my /etc/sources.list file to point to numerous other repositories to see if it was a case of the packages being missing from the repository I was using, and got consistent results. Also, the gnome-app-install tool consistently listed the Java Sun package, but didn't let me select it for installation - sorry, I should have stated this in my initial submission. Also, if the packages were missing how could I have got hold of them to manually install them? -- Installing linux-image-2.6-686 (or 2.6-686-smp) prevents installation of sun-java5-* packages https://launchpad.net/bugs/55701 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
