  Is it safe to change my Lucid sources to Maverick, to get one app, then revert to Lucid?
  I am considering to temporarily change my repositories to Maverick, on a Lucid system.
  I want to install a newer version of Evolution because it has a particular feature I want. I don't want to apply general Maverick updates.. I'm only interested in Evolution... My reason for this it to let apt/Synaptic sort out the dependencies... I suspect this could be pretty dicey if I allowed anything more than just a simple single app, but even then, it may be a bad move.. Am I courting disaster here? installation apt repository dependencies share|improve this question asked Nov 5 '10 at 10:47
  No, it's not safe. Evolution will pull lot's of updates that can break nearly anything. Looks like a fun thing to try in a Virutal Machine (with snapshots) anyway.

  Thanks.. Mission aborted! .. but a good learning moment, none the less...
  It is not the best way but will eventually work for some little application.
  But: evolution is definitely more than "just a simple single app". It has dependencies to the evolution-data-server, to many different newer gtk-libs, and so on.
  Especially since evolution got many refactoring for the move to gnome3.

  Yes, thanks.. I was looking at my "simple" and thought "someone is going to pull me up on this! :)

  Though i would not recommend it either, there is a mechanism called pinning (Just in case you ever want to install a more recent version):

  Thanks Clausi... This page is very informative and interesting... It actually warns/recommends againt itself, but it does suggest backports ... so I uncommented my backports lines in /etc/apt/sources.lists to see what showed up .... Well, Evolution didn't show up there, which tallies nicely with the warnings I've overwhelmingly received.... but it did show a few "backported" updgrades, one of which was VirtualBox-ose... I'm not moving to Maverick for a while, so this looks pretty useful... I haven't installed the upgrades yet... I think they backports are "accredited" as robust.
  If for evolution only the better way would be to add an appropriate ppa e.g.:
  sudo add-apt-repository ppa:jacob/evo230
  and install from there (in case you trust this ppa). Mind that Evolution may not exactly work the same as in Maverick and that installing other dependencies may cause instabilities to your system.
