Reluctantly, yesterday I went ahead and updated Ubuntu 7.10 to Ubuntu 8.04. After 45 minutes of downloading and 50 minutes of installing, I had problem with "gcc-3.3-doc" (which I finally deleted it after searching for an hour for solutions). Ubuntu 8.04 brought with it Firefox3, which is a welcomed Browser, but lost all my "add-ons". The most unfortunate incident was the new VirtualBox-1.6.0-OSE ( which is not an Innotek property anymore and it belongs to SUN Misrosystems). After 7 hours of figuring out how to install the "tar.bz2" and "vboxusers" rejections, when I finally saw the OS working came the most disappointing issue no USB entry, plus I can't connect to my network. VB1.5 was working like magic before. I need HELP, but please in very simple language with no abbreviations, I am 68yo and a candidate for a Heart Transplant. VB 1.6.0-OSE is built in Ubuntu 8.04 with Windows XP Professional. I appreciate your guidance and I will remain grateful forever. Theses are the last upgrades I will attempt to perform on my PC.
