Bug description:
  Zsynced my daily-live iso and installed without any errors. This is
  probably different bug, but I could not login by clicking my username,
  ubuntu did not ask me for a password and just hanged, had to write
  login and pass manually.

  After loging in I started Update. Nothing started, first I got
  "jockey-text" error and immediatly after "lightdm-example-gtk-greeter"
  error.

  I tried to report these bugs, but there was an error because launchpad
  did not recognise my report (i had to update), afterwards 2 another
  errors came up. Then I updated system and after finishing this error
  came up


  I started again Update, which launched
