Update failed, improperly signed?

I'm currently on 4.442, and I get a notification for an update to 4.457, but when I try to install the update it fails with this:


I've tried to update a couple times with the same issue. Thanks

Strangely, what seemed to be the same version(4.457) through the alpha channel didn't have that error

Sorry, it was linking to the wrong version. Should now be fixed on all update channels.

Confirmed, thanks!
