Unity not started after yesterday update.

What is happened?

1. Ubuntu launched a partial upgrade after I open "update-manager". It's normal when dev makes something in system.
2. That's removed "ubuntu-desktop" and "unity" with depencies. And install "unity8", "ubuntu-session" and etc.
3. OMFG!!!
4. Ok. Restart of the computer, and check what has been in the system.
5. LightDM started. Ufff. Login to my profile. Nothing show besides wallpaper. RMB works, window works, but nothing decorations.
6. Hmmm. I try install "ubuntu-desktop" and "unity"
7. NEIN!!! These packets is in "incoming". You can't install this.
8. Ok, how is you want. And I goes to a bed.
9. With more optimistic in the morning I waked up.
10. Login to my profile and started synaptic. Refresh apt-get index and update a system.
11. Check a "ubuntu-desktop" and "unity" to install. This packages has installed without troubles.
12. Restart. Login to profile.
13. Anything but wallpaper works. RMB works, window works, but I not see any panels and decorations. It's not good.
14. WTF?!
15. Ok. If you want. In terminal I type "ccsm". Check a checkbox in "Unity", that the launched Unity. You know who.
16. Nothing. Wait! In terminal has someting showed:

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/ccm/Pages.py", line 212, in EnablePlugin
    if conflict.Resolve():
  File "/usr/lib/python2.7/dist-packages/ccm/Conflicts.py", line 306, in Resolve
    answer = self.AskUser(self.Plugin, conflict)
  File "/usr/lib/python2.7/dist-packages/ccm/Conflicts.py", line 445, in AskUser
    msg = msg % protect_markup_dict (msg_dict)
UnboundLocalError: local variable 'msg_dict' referenced before assignment

This is propably a local problem, but I don't know how fixed this.
