unity - Ubuntu 16.04 launcher is missing after installing new updates

I upgraded to 16.04 from 15.10 and every things was good. After installing new updates, launcher, menus and top panel disappear when I login.

I tried this commands:

dconf reset -f /org/compiz/
setsid unity

Also used ccsm command and checked that Unity plugins is enabled. Still problem exists.

How to solve this?

After spending so much times and searching, I tested almost all the solutions on the internet.

1. Problems after upgrading to 14.04 (only background and pointer after login)


2. Launcher disappeared


3. Ubuntu 16.04 no menu bar or launcher - help!

But problem didn't solve. Totally the only solution which worked for me was follwing this instruction:

1. open /usr/bin/ and run gnome-terminal.real


2. run adduser newuser to create a new user


3. run kill -9 -1 to logout


4. login using newuser


5. do #1 again


6. run su olduser and enter your password


7. run mv /home/olduser /home/olduser_backup


8. run mkdir /home/olduser


9. run chown olduser:olduser /home/olduser


10. run reboot


11. login using olduser

Totally you can delete newuser by running these commands:

sudo deluser newuser
sudo rm /home/newuser -rf
