dnssec-key 'unknown algorithm RSASHA512'

[pvs]

Hello,

I'm  using ubuntu 22.04 server on which bind 9.18.8 service is running.

I'm trying to generate dnssec-key by using the command  "dnssec-keygen 
-a RSASHA512 -b 2048 -n zone example.com"

After doing this, it is generating both public key and private key.  
When I generate a file with aprivate key in /etc/bind directory, it is 
throwing error  'unknown algorithm 'RSASHA512'

Same error is thrown when tried with other algorithms like 
ECDSAP256SHA256, RSASHA1, RSASHA256 etc

Any help is greatly appreciated.
