Ubuntu upgrade from 12.04 to 14.04

I’ve recently upgraded my Ubuntu 12.04 to 14.04, using the release upgrade tool. Normally I would do a clean installation, especially with a major release upgrade like this. But I heard good things from others in doing an in-place upgrade so went with that. Reinstalling packages and setting them up again is time consuming. Anyway, all went well with only a few gotcha’s on the way. I’ve listed them below.

Some things to watch:

  • Multiple desktops disabled
  • Parcellite didn’t work
  • No Startup Applications in main menu
  • Apache local didn’t work (VHost files need a ‘.conf’ ending)
  • Apache updated from 2.2 to 2.4, see http://httpd.apache.org/docs/2.4/upgrading.html for full upgrade details
  • Ctrl-Alt-P no longer works in SublimeText3
  • Alt-Tab switcher was showing windows on all desktops
