      I get that error on these queries:

      db.music.update({ 'rounds.0.groups.0.teams.crawlerTeamId': '69',
  id: 'iranLeagueEvents-1393' }, {$set: { 'rounds.0.groups.0.teams.$.standing': 
   { crawlerTeamId: '70'} });

      or this one StackOverFlow

      db.music.update({genre : "Grunge", "bands.0.albums.0.tracks.order" : 1}, {$set:{"bands.0.albums.0.tracks.$.name":"Smells Like Teen Spirit!"}})

      I'm using "$" positional per update in a project, It was working without any problem in Ubuntu (mongoDB 2.4), I cloned the project into Archlinux and i get this error on db.collection.update:

      { [MongoError: The positional operator did not find the match needed from the query. Unexpanded update: rounds.0.groups.0.teams.$.standing]
  name: 'MongoError',
  code: 16837,
  err: 'The positional operator did not find the match needed from the query. Unexpanded update: rounds.0.groups.0.teams.$.standing' }

      while I'm sure that the find query always match only one object in mongoDB.
      Seems the last version of mongoDB broke backward compatibility of this functionality.
