@ibrakalifa extract the Ubuntu image and put it on your SD card or in MyDocs, then edit /home/user/.chroot to point to the Ubuntu image. If you didn't understand what I just wrote, I would strongly recommend you use the "main" Debian image for learning Linux. @fw190 @Estel : I was hoping you would give me technical reasons why LibreOffice is superior. If there are only political reasons why LibreOffice is better for the N900, then I think that it isn't worth the headaches of migrating for most Easy Debian users.
