Unable to update or repair FTL to 4.2.3

amanmore · March 24, 2019, 4:53pm

Expected Behaviour:

FTL 4.2.3 should download and install during the update or repair process (pihole -up and -r)

Actual Behaviour:

After "Downloading and installing FTL" for what feels like at least 10 minutes, the following appears:

  [i] Downloading and Installing FTL...curl: (56) SSL read:curl: (56) SSL read: error:00000000:lib(0):func(0):reason(0), errno 104
  [✗] Downloading and Installing FTL
  Error: URL https://github.com/pi-hole/FTL/releases/download/v4.2.3/pihole-FTL-arm-linux-gnueabihf not found
  [✗] FTL Engine not installed

Debug Token:

https://tricorder.pi-hole.net/q52urppg76!

I have already tried changing the resolv.conf IP to a standard one, with no luck, and changed it back, and have run sudo apt-get update and sudo apt-get upgrade. Neither of them seems to have fixed this issue.

Error 104 looks like it's a connection reset by peer, which would be a problem with Github and their servers.

Can you run curl -o /tmp/pihole-FTL https://github.com/pi-hole/FTL/releases/download/v4.2.3/pihole-FTL-arm-linux-gnueabihf to completion?

That command seems to work fine

pi@raspberrypi:~ $  curl -o /tmp/pihole-FTL https://github.com/pi-hole/FTL/releases/download/v4.2.3/pihole-FTL-arm-linux-gnueabihf
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

Okay, you can just run sudo mv /tmp/pihole-FTL /usr/bin/ and then sudo service pihole-FTL restart. Everything should be up to date at that point.

After doing that, it seems the Pihole is no longer able to connect to the API

Upon running pihole -r, I get the following:

  [✗] Downloading and Installing FTL
  Error: Unable to get latest release location from GitHub
  [✗] FTL Engine not installed

I ran pihole -d again, but wasn't able to upload the debug log from within the function

EDIT: I was able to upload it after changing the resolv.conf IP again:

What is the output from sudo getcap /usr/bin/pihole-FTL and ls -la /usr/bin/pihole-FTL?

amanmore · March 24, 2019, 6:17pm

Here's what I got:

pi@raspberrypi:~ $ sudo getcap /usr/bin/pihole-FTL
pi@raspberrypi:~ $ ls -la /usr/bin/pihole-FTL
-rw-r--r-- 1 pi pi 620 Mar 24 23:28 /usr/bin/pihole-FTL

DanSchaper · March 24, 2019, 6:20pm

Alright, run the below:

sudo chmod 755 /usr/bin/pihole-FTL
sudo chown root:root /usr/bin/pihole-FTL
sudo service pihole-FTL start

After that check with sudo systemctl status pihole-FTL

amanmore · March 24, 2019, 6:24pm

Here's the output:

DanSchaper · March 24, 2019, 6:27pm

Is everything working?

amanmore · March 24, 2019, 6:29pm

No, the admin webpage still says "Lost Connection to API", shows the DNS Service and FTL as not running, and doesnt show a version number at all for FTL at the bottom right

DanSchaper · March 24, 2019, 6:29pm

Okay, what does pihole -v show? And run another debug if you could please.

DanSchaper · March 24, 2019, 6:30pm

And just to make sure things are in the right place, try pihole -r and repair.

amanmore · March 24, 2019, 6:33pm

  Latest FTL version is ERROR

The debug log was having an error while uploading again. I had to change the resolv.conf to google's DNS again, and this time I got

https://tricorder.pi-hole.net/d9qhozbgfv!

DanSchaper · March 24, 2019, 6:34pm

Okay, run pihole -r the curl command pulled down the text of the web page instead of the actual binary file.

amanmore · March 24, 2019, 6:45pm

It seems to have gotten stuck at

  [i] Downloading and Installing FTL...

again. It has been on that for the past 10 minutes.

EDIT:

  [i] Downloading and Installing FTL...curl: (56) SSL read: error:00000000:lib(0):func(0):reason(0), errno 104
  [✗] Downloading and Installing FTL
  Error: URL https://github.com/pi-hole/FTL/releases/download/v4.2.3/pihole-FTL-arm-linux-gnueabihf not found

amanmore · March 24, 2019, 7:21pm

I think I may have fixed it.

I downloaded the binary from https://github.com/pi-hole/FTL/releases/download/v4.2.3/pihole-FTL-arm-linux-gnueabihf on another device, renamed it to "pihole-FTL", moved it over to /tmp/ using SFTP. Then I did, in order:

sudo mv /tmp/pihole-FTL /usr/bin/
sudo reboot
sudo chmod 755 /usr/bin/pihole-FTL
sudo chown root:root /usr/bin/pihole-FTL
sudo service pihole-FTL start
sudo nano /etc/resolv.conf

changed the IP to 8.8.8.8

pihole -r

Now it seems to be working. I'm guessing Github's servers in my location are probably having a few issues.
