[tor-relays] upgrade problem

[potlatch]

Wondering if my tor.list has a typo since I can't upgrade Tor 0.4.5.9.  I get error:
Err:1 https://deb.torproject.org/torproject.org stretch/main amd64 tor-geoipdb all 0.4.5.10-1~d9.stretch+1
  server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
I have debian 9 installed.  Can someone turn on the light for me?
Thanks, potlatch
