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
