My Apple Ultra2 watch will not search for updates.
"Unable to check for update. An error occurred while checking for a software update."
I rebooted. No help.

(4,486 posts)I assume you have done that. Is your iphone updated to the latest version? If not you may want to update the iphone first.
The latest version currently out is watchOS 26.

(4,486 posts)release, in case I need to roll back.
So far I have had no issues with version 26 on both the iphone and the ultra 2.
That is strange that you cannot update you ultra watch.
When I did the update it took quite a long time to update the watch, about 2 hours. First it downloads to the iphone, then to the watch. I just assumed there was a lot of traffic on the server which was why it took so long to download on the iphone. When downloading the watch IOS to the iphone, it didn't give too much indication of any progress bar for what it is worth.
