Guys, I have managed to update the software using iTunes app in my windows PC. This by passed the issues with wireless updates over wifi. So, I recommend to do it that way.

Connect iphone to your Mac, go to finder. It will download the software and install it on your iphone.

The update was just released yesterday and it may take time for the rollout to become fully implemented. Patience.
Make sure you back up to iCloud or your computer before doing the update and this might be a good time to clean out apps you no longer use.

Delete any old partial downloads in iPhone > Settings > General > iPhone Storage > sort by size and look for failed or partial downloads. Then do a forced restart and try again, using an available iOS 26 update first.

I am facing the exact same issue on my iPhone. When I try to update to iOS 27, it gets stuck on 'Update Requested' and then shows 'Software Update Failed'. Has anyone found a solution for this yet?"
