At what point is it better to just install the OS from scratch?<br></blockquote><div><br>in my experience you can sometimes get away with upgrades, but more often they bite. lucid to maverick croaked. it's always better to install from scratch. my favorite approach is install in another partition (the installer can help you shrink an existing partition if you don't already have one available). a lean OS install can fit in under a gig, 2g will be plenty for most any install. more is better of course, but i've done with less and done fine. anyway that way your data, and even your current OS, are still there, AND you have a fresh and clean install. i usually finally reuse the prior partition when i'm ready to install yet another release.<br>
