DOH failed at install (Pi4): exec format error

[0MiguelAnge0]

Expected Behaviour:

To install Cloudflared successfully in my Raspberry P4 running Pihole

Actual Behaviour:

I am following the guide here: cloudflared (DoH) - Pi-hole documentation

I duplicate the install steps for arm64. But when trying to execute the binary it fails.

Debug Token:

After typing 'cloudflared -v', following error pops up:

---

Cannot execute binary file: Exec format error

Please post the output of " uname -m"

Also, if you meant to include a debug token it is missing.

Hi,

Thanks for your hints!

What do you mean about the “uname -m”?

Well, about the token, do not figure out as well how to get it... I am just following the installation guide and it got stuck after cloudflared -v

My Pi is up to date and I tried in two Pis with same result.

Anyway I am ok to provide more debug hints once I will get how to do (my linux skills are not that high...)

Sure.

I believe the issue may be you’re following the instruction for the wrong Linux architecture.

At the console of you pi enter the command - uname -m

Tell us what the output is.

Well, it returns: armv7l...

Well, I picked up the unstaller for a 64bits architecture.

Maybe I got wrong between the Arm Core Architecture (Pi4 uses a 64bits SoC) and the OS Debian which is a 32bits system...!

Thus, I guess, I shall use the userguide for the 32bits variant...

Hi,

Thanks for your hint. So I ran the 32bits Pi installation and all went good! Well, asking a 32bits OS to run a 64 bits binary might be not that easy (I am using Noobs).

Well, it could be great in the Pihole/DoH userguide to add the -uname-m check to suggest which type to be selected, unless it is obvious for everybody but me!
