Pi-hole gives the impression of working.

When I have issues updating Pi-Hole, I think of it like this:

You are running the same program you are trying to update.

I would try changing your DNS to something like quad9 or "nextDNS" they both seem like great options. Or, cloudflare also has a few filtered options as well.

Then, you could temporarily use them as your main DNS server just until you get the program updated.

4

This has no bearing. Pi-hole is involved in the DNS query only. After that, the URL is loaded, the software is downloaded, etc. The choice of DNS server for the Pi-hole host does not change any of this.

5

Please upload a debug log and post just the token URL that is generated after the log is uploaded by running the following command from the Pi-hole host terminal:

pihole -d

or do it through the Web interface:

Tools > Generate Debug Log

This will temporarily reset the nameserver on the Pi to bypass Pi-Hole DNS.

sudo nano /etc/resolv.conf

Edit the nameserver line to nameserver 9.9.9.9 or your preferred third party DNS service, save and exit

Run

pihole -d

and upload the debug log.

No change!
I have working dns on this pi. I can resolve github.com but curl cannot download the file. I do not know where the debug log is uploaded to but curl cannot upload it. It is not an issue with my network as I have another pihole installation that is happy. This install was happy until I upgraded to bullseye. If it is not a known problem I can wipe and reinstall.

PM this file to me. May take a few PM's to get the whole file.

/var/log/pihole/pihole_debug.log

10

Did you receive my PMs?
