I downloaded some music the other day, and then discovered that it was in .flac format. While I could have listened to it using VLC Media Player, I wanted to copy it to my iPod Touch to listen to it.
Luckly the guys over at SimpleHelp.net have a good guide on How to convert .flac files to .mp3 using Ubuntu Linux and Windows.
Not only that, but I was able to do it using Portable Ubuntu running off my LaCie 8GB USB key.
I have a few problems installing the gstreamer0.10-plugins-ugly-multiverse package, but I found the trick was to install soundconverter application, and then use the link in the application for installing the missing MP3 codec.
