I had the same problem -- tried to install iOS 15.7 on iPhone 8 and got the "software update failed" error.


Here's what worked: I freed up enough storage space until I had about 9 GB free. That's it.


I originally tried when I had about 4-5 GB free. It didn't install, and I got the exact same error as above.


I tried again when I had about 7 GB free. It still didn't install; same error.


Once I freed up enough storage space (by deleting apps and things) until I had about 9 GB free, then the update installed, no problem.
