What you were trying to do (and why) Trying to install the base linuxbrew with the vendor-ed ruby on 32-bit Debian 9 (old 2008 macbook) $ sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"

What happened (include command output) Fails with an error from tar (because I think curl returns a 404).

- What you expected to happen
Expected at least a better error message with instructions on how to install a suitable version of ruby or at least a more helpful "Sorry, this arch is not supported.
- Step-by-step reproduction instructions (by running `brew install` commands)

Hi. Please always fill out the issue template.

We do not support 32 bit platforms for the time being. See https://docs.brew.sh/Linuxbrew.

Linuxbrew does not currently support 32-bit x86 platforms. It would be possible for Linuxbrew to work on 32-bit x86 platforms with some effort. An interested and dedicated person could maintain a fork of Homebrew to develop support for 32-bit x86.

lmergner commented 5 years ago

Yes I understand the architecture is not supported. Could you consider a more helpful error message in such cases?

iMichka commented 5 years ago

I think yes. We could bail out directly in this script in case we hit a 32 bit case: https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh

@sjackman What do you think?

lmergner commented 5 years ago

I'm not a ruby person so I don't know if I can install a version that linuxbrew supports and indicate that with an env var. If that's possible, it would be nice to document that on the vendor install failure.

I suspect it must be a pain to support error messages like this for every case, but it'd be a bit help to know why the shell one-liner on the website failed.

Thanks.

I've opened PR https://github.com/Linuxbrew/install/pull/46 to check the CPU type. This PR also addresses the issue that ARMv7 would fail to download the appropriate bottle for ARMv6.

As long as you understand that you're in uncharted territory, I'm happy to point you in the right direction. Install a Ruby version ≥ 2.3.7 (ideally exactly version 2.3.7), add it to your PATH, and then run the installation one liner. Feel free to comment here if you run into any more trouble.
