SG-2400 crashed manual update has more issues

[detox]

hello all….
My Netgate SG2400 crashed during upgrade from 2.3 to 2.4
Found a 'work around' command of: 
pkg static update -f
pkg static upgrade -f via ssh
This upgraded to 2.4.2-RELEASE-p1

But now I cannot install any packages with error of " WARNING: Current pkg repository has a new OS major version. pfSense should be upgraded before doing any other operation Failed"

Can anyone help?

Thanks

UPDATE:    After talking with Mr Google again, I found a reference to a previous post on this forum ( https://forum.pfsense.org/index.php?topic=141776.msg773610#msg773610 )

It suggested using this command from terminal :  pfSense-upgrade -d

I did so, rebooted and now I can install packages

I shall not ask fro the technical reasons on why it failed, or how my manual attempt to fix a crashed appliance possibly contributed.

However, if someone would be willing to provide speculation on the why's, I would be quite appreciative
