Raspberry Pi new install cannot download binary

[jinapatton]

Okay, so cleared the otm directory completely to allow for a fresh download

root@pihole:/# mkdir otm
root@pihole:/# cd /otm
root@pihole:/otm# cd ~
root@pihole:~# systemctl daemon-reload
root@pihole:~# systemctl start otm.service
root@pihole:~# systemctl status otm.service

Popped into the otm directory, and starter was there:

root@pihole:~# cd otm
root@pihole:~/otm# ls
starter.sh

I had cleared the otm log, after this above execution, fresh output.

root@pihole:~/otm# cat /tmp/otm.log

The reason this is showing us because it is the Linux binary that is being run, not the ARM one.

There might be a bug in the new method we've started using. It seems even when you select Pi, it's giving you the Linux binary.

I can have the developer that works on this look at it tomorrow and fix it. Once it's done, I can update this post.

We appreciate your letting us know because we were not aware of this issue.

[jinapatton]

I'm happy to be your test bed for this fix. I already have a script wrote to wipe both logs and the /otm folder.

[OutagesIO_Support]

Thanks for your patience. We'll certainly fix this tomorrow and update you also.

[OutagesIO_Support]

Question, what hardware exactly are you using? Which version of Pi, make and model please.

[OutagesIO_Support]

We see that everything is fine, the service is downloading the correct binary. We suspect that the hardware is not compatible with the aarch64 ARM binary.

For a test, please download the binary directly, then make it executable, then just run it like ./arm64_otm_1_81_2401

https://downloads.echonets.com/otm/arm64_otm_1_81_2401

Let us know the make/model of the Pi and what happens when you run it manually.

[jinapatton]

Raspberry Pi 3 B+ with 10 / Buster.

240K -rwxr-xr-x  1 root root 239K Sep 11 15:57 arm64_otm_1_81_2401
root@pihole:/otm# ./arm64_otm_1_81_2401
bash: ./arm64_otm_1_81_2401: cannot execute binary file: Exec format error

I can format it to 11 / Bullseye, but if that's still too old I can grab a new one, as I run a pi-hole I'll maintain a raspberry pi for my installation.

[OutagesIO_Support]

The Raspberry Pi 3 B+ typically runs a 32bit operating system by default, even though the hardware is 64bit capable.

If you're using a 32bit OS, the binary cannot work.

The binary is compiled as a 64bit executable, it won't run on a 32bit OS, which is likely the cause of the error you're seeing.

Here’s how you can check:

Confirm OS architecture: Run the following command to confirm if your OS is 32bit or 64bit:

uname -m

If the output is armv7l, it’s a 32bit OS. If it’s aarch64, then it’s 64bit.

Try running this against the binary that gets downloaded;

file /otm/otm_binary

[OutagesIO_Support]

Sorry, I didn't' see your reply before completing mine. Yes, you would need a 64bit OS running on the device for otm to run on this.

Hope this helps to solve the mystery.

[jinapatton]

All good, cleared up for now. Ordered a Pi 5, will be here tomorrow.

[OutagesIO_Support]

Great, let us know how that goes. It should work no problem.

[jinapatton]

Alright, we're in business. Purchased a Pi 5 for the PiHole / OTM client, working grand. The Pi 3 was formatted to the latest OS, and brought up as a purely OTM client.

Should I start a new thread about moving licenses and renaming things to let this be as something searchable for others in case they see this themselves?

[OutagesIO_Support]

If it's s different topic, best to start a new one otherwise, it gets lost in the thread. If you don't mind :).
