Is iOS 14.8 good for iPhone SE (1st generation)?

I have an SE 1st gen. I just tried to update the software 14.8

It all goes well until the last few seconds where it stops and says there's an error but with no error code

I rang support but Catherine said that my SE did not support 14.8???

So is 14.6 the end of my software upgrades on this phone?

any ideas why my SE is failing to download even the 14.8.

I don't use the iCloud but have cleared enough space and plugged it into my new iMac...oh this is not the computer my SE is backed up to, would it help if I was plugged into the iMac its backed up to?

It's a security update. It's good for any iPhone which is capable of running it. And your phone is capable of running it, so yes, you should upate.

You're welcome.

No. An iPhone SE 1st gen can be updated to the current iOS version iOS 15.
