[✓] Detected ARMv6 architecture
[✗] Failed to retrieve latest FTL release metadata

I set /etc/resolv.conf to 9.9.9.9 already, which resolved it giving me an unable to access github error. However, instead of an immediate github error, it now runs for a second and gives me “failed to retrieve latest FTL release metadata” and stops running.

Debug Token:

errors out. curl failed.

Do you know what was the Pi-hole version before the update?

If it was Pi-hole v5.x, this may be a little incompatibility between the v5 pihole -up and the current v6 FTL binary file name.

Please try sudo pihole -r to repair the installation.

Does this work or it also fails?
