SSH key warning message in terminal, should i be worried?

Installing and Using OpenWrt

I got this message trying ssh to my router. Should i be worried ?

Things that happened with the rooter: Perform reset (on vendor firmware), Updated all installed packages.

To get rid of this message i removed offending key from known hosts to be able to use ssh again.

Any thoughts ?

No, this is normal if you've recently reset or reflashed (or replaced) the router. Just remove the offending ssh key from your known hosts file on your computer.
