I recommend installing from source (install rust with https://rustup.rs and then run the cargo install command as in the README)-- the binary in the releases page is only 64 bit which is not with your 32 bit system.

It looks like curl is not built with http2 — can you try reinstalling curl or see if there’s a way to install it with http2 support? This is an issue with simply downloading a dependency for cargo (not even at the installation step).

Hi! I'm facing the same issue, but with a 64-bit system. I'm trying to use it on a Raspberry Pi 4 running Ubuntu 18.04.4 LTS (GNU/Linux 5.3.0-1026-raspi2 aarch64)

I used curl -LJO https://github.com/agrinman/tunnelto/releases/download/0.1.12/tunnelto-linux.tar.gz to download it and tar -xzf tunnelto-linux.tar.gz to extract it. Trying to run it, I get this error zsh: exec format error: ./tunnelto

I tried installing it through rust but compiling on a Raspberry Pi takes far too long.

It works. Thank you so much.
