How do I update Java, Flash, and Opera?

Do I use sudo apt-get install?

[krishna.murphy]

That's one way to do it! Linux is justly famous for having MANY ways to do everything, more or less. There are command line apt-tools like apt-get and aptitude, as well as GUI tools like the synaptic package manager on the Knoppix Preferences menu. Keep in mind that ***apt*** is not the only way, either; there's gdebi to install a manually downloaded .deb archive, as well as the underlying facility of dpkg. I even set the GUI to auto run gdebi whenever I double-click-to-run a .deb archive from e.g. the Desktop.

These are not the only tools out there, either. There are far more than I know - I just learn about them as I go, and muse on how I (we) came to be so fortunate in having the Linux/open-source community writing LOTS of code, forums like this one, wikis, FAQs, etc. for my (our) use. I highly recommend that you READ the documentation, both by searching online and from the terminal command-line by typing e.g. man dpkg, man aptitude, etc.

Cheers!
