Error after update 2.2.0 update (4 replies)

Hello,

This morning I was notified to update to 2.2.0 version. As usual I proceed to automatic update, and after the process is done, when I want to enter the dashboard I have this error:

Variable "sites" does not exist in "@CoreHome/_siteSelect.twig" at line 27

But when I go into settings, all my sites seems to be there. Also I added a new one just to test, and I was able to add it.
Any hints please?
