Since you don't have net access on that machine, check
/var/cache/apt/archives for the NetworkManager .deb.  It should be there
unless you cleaned it out (a great reason to not clean out the cache
unless you really need the space).  Wicd obviates other network
connection managers (and vice versa).  Reinstalling NetworkManager
should remove Wicd.
