Conversion failed. Please correct the error and try again.

The RPCNFSDCOUNT is meant to be only a number. "-V 2" is an invalid option there. This worked in previous ubuntu releases because even though the parameter is called RPCNFSDCOUNT (i.e., a count, expecting a number), it was just passed straight to the rpc.nfsd command line.

I'll see if there is an update to this conversion script to handle that, but in the meantime, please remove the "-V 2" from RPCNFSDCOUNT and adjust your preferences in /etc/nfs.conf and /etc/nfs.conf.d/local.conf after the conversion script is run.
