I have deleted several apps and powered off a couple times but still can’t get my IPad to update

There are several causes for failure of your iPad to update - including insufficient space.

Other common issues for update issues are attempting to update over a Cellular connection (updates can only be accomplished over WiFi) - or if the iPad has less than 50% battery charge.

These resources may be helpful with troubleshooting the problem:

Update your iPhone, iPad or iPod touch – Apple Support

If your iPhone, iPad or iPod touch won’t update - Apple Support

If you see an error when you update or restore your iPhone, iPad, or iPod - Apple Support

If the reason why it won't update is because there is not enough space, you will have to delete more, especially photos which take up a lot of space. Be sure to save important photos to your computer or external drive.

If space is not the problem, check this link...
