Howto: Upgrade PlayOnLinux to version 4.0 on Ubuntu 11.04 (Natty Narwhal)

Under Ubuntu 11.04 (Natty Narwhal) I have been using PlayOnLinux for a while to install a variety of Windows programs (for example: Internet Explorer 7). After my upgrade from the 10.x Ubuntu series to the newest 11.04 version, I noticed that I was no longer able to install any programs within PlayOnLinux. The Ubuntu repositories offer version 3.8.8 of PlayOnLinux (at the moment of writing) resulting in the message ‘Sorry, PlayOnMac 2.5 and PlayOnLinux 3.8 are no longer supported.’ when attempting to install software. This short blog describes how you can update your PlayOnLinux version to the newest 4.x series that works correctly under Ubuntu 11.04.

First, add the PlayOnLinux repository to your list of sources. Do this by issuing the following command:
{code}sudo wget -O /etc/apt/sources.list.d/playonlinux.list{/code}

The result of this command should look like the example below:
{code}You@Your-PC:~$ sudo wget -O /etc/apt/sources.list.d/playonlinux.list

Saving to: `/etc/apt/sources.list.d/playonlinux.list’

2011-08-20 22:57:08 (4.30 MB/s) – `/etc/apt/sources.list.d/playonlinux.list’ saved [43/43]{/code}

Now that you have added the repository, you need to update aptitude with the command sudo apt-get update. This will update all repositories and throw an error which you can ignore. The error should look as follows:

{code}W: GPG error: natty Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY E0F72778C4676186{/code}

Now that everything is up-to-date you can either install PlayOnLinux if it is not present yet (sudo apt-get install playonlinux) or upgrade the software to the newest version using sudo apt-get upgrade. While processing this command, you will be warned again that the PlayOnLinux packages cannot be authenticated. You can then choose to install this packages without authentication to succesfully update PlayOnLinux to version 4.x:

{code}WARNING: The following packages cannot be authenticated!
Install these packages without verification [y/N]? y{/code}
