openSUSE-Leap-15.3-DVD-x86_64-Current.iso checksum mismatch

I am upgrading from Opensuse 15.1

Why do you need ISO then? Just do online upgrade.

Thus when you install the original and then do a zypper patch (or zypper up), which is of course strongly recommended, you will end with the same situation.

As long as ISO boots. There was problem with shim included in original ISO that failed to boot on quite some systems. I think this was one of the primary reasons for refresh.

Online upgrades have their own issues, and not everyone has stable internet.
