    This process apparently installs the 32-bit version of Java. Any instructions on how to install the 64-bit version? (because the 32-bit version won’t run on 64-bit Ubuntu 13.04). Thanks

    Works fine up until the point:
    “sudo apt-get install oracle-java7-installer”

    Just get the error message
    E: Unable to locate package oracle-java7-installer

    Did I mess something up?

  21. Eddie says:

    The only problem with this approach since 2013 is that Java release a massive 100Mb+ update every few weeks via an incredibly slow repo at http://download.java.net/

    It can take up to 20 minutes to down the 100Mb using a 120Mbps connection. It often times out and you have to start again.

    I don’t know why Java have changed their working practices – probably weak security, but so many big and slow updates is unprofessional.
