To convert a Midi File to Mp3 in Ubuntu, the easiest method I found (on ubuntuforums) uses the power of timidity:
sudo apt-get install timidity
to convert to mp3 either use ffmpeg
timidity My_midi_file.mid -Ow -o - | ffmpeg -i - -acodec libmp3lame -ab 64k my_converted_midi.mp3
or use lame
timidity my_midi_file.mid -Ow -o - | lame - -b 64 my_converted_midi.mp3
In Ubuntu as an alternative to fineprint, page-crunch is suggested, but I don't find it useful, as multiple sheet printing is also available with the normal printing menu in ubuntu.

The easiest command I found, is using avconv. To install avconv in Ubuntu, open a terminal (Alt+Ctrl+t) and enter
sudo apt-get install libav-tools
To convert a video from .avi to .mp4, just use
avconv -i InputVideoName.avi outputVideoName.mp4
To change the size of the video you can add the -s flag, e.g.
avconv -i InputVideoName.avi -s 720x540 outputVideoName.mp4

sudo apt-get install virtualbox
but rather download and install it from the Oracle virtualbox website. Otherwise the USB port is not working, (see stackoverflow). I also encountered problems to install the Guest Addition, when installing virtualbox from the repository.
Sometimes the packages in Ubuntu are outdated (e.g. the geometry package in Ubuntu 12.04, see this forum) and it is necessary to manually include the package.
The easiest way for me is to just download the package from ctan, e.g. for the geometry package
