Expected Behaviour:

  • Name resolution by the pi-hole succeeds.
  • Running pihole -up succeeds.

Actual Behaviour:

Running pihole -d -c or pihole -up produces:

*** [ DIAGNOSING ]: Operating system
[✗] Distro:  Ubuntu
[✓] dig return code: 0
[✗] Error: Ubuntu is not a supported distro (https://docs.pi-hole.net/main/prerequisites/)

Running dig flurry.com produces:

Actually, you have a networking issue and Pi-hole is unable to retrieve the list of supported distros, resulting in failure to correctly identify Ubuntu.

You can see the communications error message in the debug log and dig output:

*** [ DIAGNOSING ]: Operating system
[✗] Distro:  Ubuntu
[✓] dig return code: 0
[i] dig response: ;; communications error to <IP>#53: timed out
[✗] Error: Ubuntu is not a supported distro

Note:
You can find the debug log in /var/log/pihole/pihole_debug.log
