spamd error: config: no rules were found

I skackpkg upgraded all my Slackware64 13.2 three days ago, which included and upgrade to spamassassin 3.4.2. Now when I run spamd I get:
Code:Sat Apr 4 18:16:21 2020 [1823] error: config: no rules were found! Do you need to run 'sa-update'?
Sat Apr 4 18:16:22 2020 [1818] error: child process [1823] exited or timed out without signaling production of a PID file: exit 255 at /usr/bin/spamd line 3034.sa-update runs except it's apparently having trouble restarting spamd:
