[DNS Resolution Currently Unavailable] during update, shut down

crediblehulk · February 22, 2025, 1:30pm

I attempted to update last night to the latest pihole install, but the system stopped halfway through. It was hanging on "DNS Resolution Currently Unavailable." After a couple of minutes, I closed the terminal window, and now the pihole appears to be gone. I cannot ssh into it, and it is no longer available in my browser at the expected IP address.

By the way, I'm NOT an expert by any means. This was always a weekend fun project for me, so if I need to reinstall, I'd really appreciate being pointed to the best guide.

I've been running the latest Pi-Hole on a Raspberry Pi 4. I use Mac OS.

Thanks in advance for taking the time to help.

I had the same issue, although I can still 'control' my VM (albeit not via SSH, but with the virsh command). The VM can now ping devices on the network, but can't reach out to the internet anymore.

I uninstalled Pi-hole, but that didn't resolve the issue, and without internet access, I can't reinstall, of course.

I assume there are some DNS settings that need fixing, but I haven't got around to digging for answers...

ErikDB · February 22, 2025, 2:14pm

If you change put nameserver 8.8.8.8 in /etc/resolv.conf, DNS is fixed temporarily. However, Pi-Hole overrides the file during installation... So it's a catch 22.

Stupid that I uninstalled Pi-Hole... Otherwise I could have run a debug log.

Pi-hole itself does not touch its host's DNS. Which network stack do you use? systemd-networkd, ifupdown, dhcpcd? Check its settings, where the DNS seems to be configured to be Pi-hole/127.0.0.1, and change it permanently there.

ErikDB · February 22, 2025, 2:28pm

Doing what's suggested here temporarily fixed the issue, so I could at least install Pi-Hole again.

It then didn't work until I reset my DNS server to 127.0.0.1#5335 in Pi-Hole's GUI (I use unbound).

My issue is resolved, but this isn't my thread, of course. Apologies, @crediblehulk. But maybe my link helps you as well?

cmdrfletcher · February 22, 2025, 2:43pm

I had the same problem. My Pi-Hole runs on a Proxmox LXC . Shortly after the update started, I got the message

[✗] DNS resolution is currently unavailable

And then nothing worked anymore. I started again with

sudo PIHOLE_SKIP_OS_CHECK=true pihole -r

Now I had to set the DNS to 8.8.8.8.

After that the update went through but Pi-Hole was still broken.

Only a Proxmox backup restore could save me.

I'm still waiting with the update.

Hello!

I have the same problem and have no idea what to do to update and have a clean running system again.

Since my Pihole runs on a Synology VM, I simply reverted to the previous night's snapshot, and for the time being, all is well again - but no update possible.

Maybe the experts here can explain in less tech speech what to do? I am rather an average user, and the posts provided previously haven't enlightened me much, sorry.

Ian_Eletz · February 26, 2025, 7:24pm

So I was able to get a functional system again.

Once I unplugged my pihole, my SD card was corrupted. I needed a new one. I then started from scratch and reinstalled the lite OS and a fresh install of pihole. I was then able to restore from a teleport backup I made six months ago or so.

I didn’t need to do new things with my router as the MAC address of my pihole was the same. (The IP address I reserved for it was still functional.)

There were a few lingering issues with trying to ssh into the system through terminal, but Chat GPT was actually a big help.

Good luck.

7wells · February 27, 2025, 9:18am

Does anybody know if the problem is only a temporary one, i.e. very likely to resolve with another pi-hole release version, or can please explain in digestable language (), how an average user can resolve it? Thank you!

MichaIng · February 27, 2025, 12:13pm

Did you try the update before February 23rd, respectively was it trying to update to Pi-hole core v6.0.4 already? If so, we'd need logs to help you, do know why Pi-hole's upstream DNS was not migrated. v6.0.4 fixed a reason for failing migration. So if you tried before it was release, just try again.

If you want to avoid the issue in any case, let the Synology use an upstream DNS directly, instead of Pi-hole. For a server, there is usually no reason to use Pi-hole, as you do not browse the web from a server system where you would need to block ads and trackers. Naturally, using Pi-hole on its own host implies this exact risk, that certain maintenance might saw off the branch it is sitting on.

7wells · February 27, 2025, 8:32pm

No, later. If I temporarily change my DNS settings and start the update again, will it then work?

MichaIng · February 27, 2025, 11:46pm

Yes, if the Synology itself does not use Pi-hole, it should not run into this " DNS Resolution Currently Unavailable" error.

But it would be also interesting to why/how it failed with Pi-hole v6.0.4 installer. Do you have the logs from the update? There should be something like this:

  [✓] Migrating Pi-hole configuration to version 6
    Migrating config to Pi-hole v6.0 format
    Reading legacy config files from /etc/pihole/pihole-FTL.conf
       PIDFILE: Empty path is not possible, using default
       SETUPVARSFILE: Empty path is not possible, using default
       MACVENDORDB: Empty path is not possible, using default
       GRAVITYDB: Empty path is not possible, using default

    Moving /etc/pihole/pihole-FTL.conf to /etc/pihole/migration_backup_v6/pihole-FTL.conf
    Migrating config from /etc/pihole/setupVars.conf
    setupVars.conf:WEBPASSWORD -> Setting webserver.api.pwhash to <HASH>
    setupVars.conf:BLOCKING_ENABLED -> Setting dns.blocking.active to true
    setupVars.conf:TEMPERATURE_LIMIT -> Not set
    setupVars.conf:TEMPERATURE_UNIT -> Not set
    setupVars.conf:WEBUIBOXEDLAYOUT -> Not set
    setupVars.conf:WEBTHEME -> Not set
    setupVars.conf:PIHOLE_DNS_1 -> Setting dns.upstreams[1] = 1.1.1.1
    setupVars.conf:PIHOLE_DNS_2 -> Setting dns.upstreams[2] = 1.0.0.1

which shows the two upstream DNS server entries from Pi-hole v5 being migrated. With this, the problem should not appear anymore. On some local tests, it sometimes took a few seconds and did show "DNS Resolution Currently Unavailable" a few times, but finally continued and finished the update without further interaction.

I will give it a try, but need to wait till the household members are out.

Here is the output (I selected the recommended action to disable lighttpd):

~$ (pihole -up 2> >(tee pihole_update_stderr.log >&2)) | tee pihole_update_stdout.log

I do not fully understand the problem. Yes, when I executed this update, I still had my Synology NAS (with Pi-hole running in its VM) set up with the Pi-hole's IP as DNS (as it is supposed to be and works all time in my entire home network with lots of devices).

Shouldn't there be a mechanism that overcomes the problem of the DNS itself not being ready during a Pi-hole update? Previous updates worked flawlessly, this one does not.

pihole_update_stderr.log is empty.

Apart from the last 2 lines showing warnings (which I do not understand), I cannot see any problems (being no expert at all, of course).

.
As I do not see any [✓] Migrating Pi-hole configuration to version 6 anywhere, I assume that I have to try once more with some other DNS (like Google's 8.8.8.8) for my Synology NAS. I will do this and report in a separate post.

EDIT:
Before I do this, I need to mention that the update seems to have gone through at least partly. Else, I would not understand why the WebGUI now looks a bit differently, e.g. suggesting that I shall switch to the more secure https://. Furthermore, the footer now shows:

Core v5.18.4 · Update available!
FTL v6.0.4
Web interface v5.21 · Update available!

I.e., the FTL was updated correctly, it seems, but not Core and Web interface.

@MichaIng
I had to set the DNS to 1.1.1.1 both on my gateway router and on my Synology NAS. Furthermore, I restored the previously taken snapshot of my Pi-hole (VM) instance, i.e. its state before the (partly) failed update. And then (yeah, I could have done a simple pihole -up instead):

I am a bit worried about the SQL-related error messages:

2025-03-05 12:16:46.747 CET [2422M] ERROR: SQLite3: no such table: main.antigravity in "SELECT adlist_id from vw_antigravity WHERE domain = ? AND group_id IN (0);" (1)

Should I do something about them? Open a separate thread for this?

And there is a repeated warning, too:

WARNING in dnsmasq core: Maximum number of concurrent DNS queries reached (max: 150)

.
The footer now shows:

Core v6.0.5
FTL v6.0.4
Web interface v6.0.2
