Yes, you read it right the issue that was being faced by users is now finally fixed. After the rollout began, the users had started complaining and showing grievances that the update was not being able to install. But the hard time is gone, the problem is now fixed. We got this confirmation from a forum post by an employee of Google.
Those wondering what exactly had happened, Mr. Phone gives you a quick recap. Many users had made an attempt to install the OTA update, after which the phones rebooted and the Google logo appeared. The system reverted back to 8.0. This didn't stop and happened a number of times. The system then displayed a message stating "couldn't install system update". As the image shows Orinn the community manager of Google said, that the users who were reverted to 8.0 will get a new OTA update quickly.
