opkg Package is Corrupted

Hello,

So today I wanted to install DNSCrypt-Proxy on the router, after I ssh-ed into the router and ran the command
entware-setup.sh I get the below errors

* opkg_install_pkg: Package findutils sha256sum mismatch. Either the opkg or the package index are corrupt. Try 'opkg update'.
* opkg_install_cmd: Cannot install package entware-opt.

I have installed entware on my router maybe 20 times, I had never this problem!
after I ran opkg update and then entware setup again, I get the same...
