We are in process of upgrading to ubuntu 20.04.1 lts

From which version?

B.t.w. current recommendation is to run nsd without database.
So with:

server:
  database: ""

I had issues when upgrading to 4.1.26, the SOA serial number I used was
too long. I now insert "$(date +%s)" (number of seconds after
1-1-1970) and now it works. I looked it up in the changelogs and
somewhere between 4.1.13 and 4.1.26 was this "fix".
