Switched to stable - Now it's installing and restarting fine.
Thanks everyone.

In "Updates" it shows Ubuntu touch Version 654 is downloaded.
I click on Install and get the popup "Update System" -> "Restart & Install" and "Cancel"
Pressing "Restart & Install" seems to do the same as Cancel.

This was working fine for all previous builds.
Can I initiate the update from command line (and How) ?

Thanks

Channel : Edge
Phone : Nexus 4

Add Google account is accepting the login but blocks the use of the login.

Cannot import Google contacts or login to YouTube.

Details :

Nexus 4 - updated from default repo.
System Settings : Add Account : Google
Entered google email & password (keyboard displays and works ok) .
2 factor authorization check appears on my other phone - Authorized YES

Then on the Nexus 4 shows :

"Sign in with Google temporarily disabled for this app
This app has not been verified yet by Google in order to use Google Sign in."

I assume that this is related to the Google Browser security whitelisting lately.

Any workarounds ?

Thanks
Adrian
