Jayce I am sorry if I offended you, I really appreciate your altruism by trying to help me. We are both veteran members and undoubtedly helped 100's of people in our time for little reward so I can sympathise if your offended by my comments but they were not meant in that manner.
I do not have access to; optical drive, flash drive or the most recent version of ubuntu and as far as I can tell the ways you have detailed require these items. I just want to get non-default packages off of this machine through internal user measures as opposed to a fresh install etc.
I know extended support versions of ubuntu exist but that doesn't negate the point, they managed to; write the code, alpha test normally 2-3 version builds minimum, fix the code, private beta test, fix the code, public beta test, fix the code and finally release the next version. They do that in 6 months are they on pro plus and chained to their desks? I don't like ubuntu as I believe that although they do make some changes most are minor that could be done through a patch, this keeps their download figures artificially high. I have tried a lot of linux distros in the past few years and ubuntu is just one I dislike but as I am stuck with it forced to use.
