    If I run do-release-upgrade on a 14.04 LTS system and have an older python 2.7 installed, will the upgrade wipe it out, and thus I’d have to manually reinstall?

      Ooops.. Try to boot into old kernel; hold Shift down when starting up, to enter Grub menu, and choose kernel to boot in. If it fails, try reinstalling.
