I've got an Ubuntu 8.04 LTS server. There are several packages which are "kept back" ("the following updates have been kept back:") when I do an apt-get upgrade. It's my understanding that I can do an apt-get dist-upgrade to upgrade these packages, but I have a few concerns:
1) If I do a dist-upgrade, will I be upgrading from 8.04 to higher version (8.10 I guess)? If so, what's the point of 8.04 being "long term support"?
2) Is this a "dangerous" process? I'm assuming that packages are kept back because there are new packages that they depend on. Does dist-upgrade simply pull the new packages and do a fairly straightforward upgrade, or are there caveats to look into?
