I have the same issue, I took the install link directly from the read me in my x86_64 docker container but I cannot run it because any command gives me "Invalid version".

[MeshkatShB]

Dear all, I use Windows and wanted to run the project via WSL based on the README file but I get the same error:

./lightpanda-x86_64-linux --dump https://lightpanda.io
error: InvalidVersion

./lightpanda-x86_64-linux --host 127.0.0.1 --port 9333
error: InvalidVersion

P.S.
The ./lightpanda-x86_64-linux -h command worked fine as it showed the usage descriptions.

Hello here,
Thanks for the reports.
I can't reproduce in a fedora 41 docker container.
I'll try with a VM.

Hello here, Thanks for the reports. I can't reproduce in a fedora 41 docker container. I'll try with a VM.

Hi there.

To be clear, I used Ubuntu 22.04 LTS with WSL on Windows and got the exact same error.

[krichprollsch]

Ok I was able to reproduce with a VM + Fedora41.

The check of the minimal linux for the loop version fails.
https://github.com/lightpanda-io/tigerbeetle-io/blob/main/io/linux.zig#L28-L31

The Zig's SemanticVersion seems unhappy with the kernel version format returned by Fedora.
https://github.com/ziglang/zig/blob/0.13.0/lib/std/SemanticVersion.zig#L116-L117

It appears Tigerbeetle changed the way they get the kernel version https://github.com/tigerbeetle/tigerbeetle/blob/main/src/stdx.zig#L479-L508
I think using the same way will fix the issue.

Ah ok, on my machines with older kernels (< 6.12.9) binary works fine..
I have 2 machines that have fairly recent kernels Fedora (6.12.9) and Arch (6.12.10) and binary fails on both

Though now that I have updated to latest stable kernel (6.12.9) in Fedora 41 the error has changed..

I forced a nightly build against the last version.
Can you test with the new binary to check if the InvalidVersion is fixed please?

@joshbaptiste the error.Unexpected is returned only once in the codebase.

My bad, error.Unexpected can be returned by the Zig's stdlib.

$ ag "error.Unexpected;" /usr/local/zig-0.13.0/lib/std/

721:        return error.Unexpected;

2838:    return error.Unexpected;

/usr/local/zig-0.13.0/lib/std/process.zig
1743:    if (amt != 50) return error.Unexpected;
1746:    if (!std.mem.eql(u8, label, "MemTotal:")) return error.Unexpected;
1747:    const int_text = it.next() orelse return error.Unexpected;
1748:    const units = it.next() orelse return error.Unexpected;
1749:    if (!std.mem.eql(u8, units, "kB")) return error.Unexpected;

But I think it's a different issue. If confirmed, I will close here to open a new one.

[krichprollsch]

@joshbaptiste I upgraded to the last kernel on my debian too and I reproduce the issue.
So I created #373.

I'm closing this one b/c the InvalidVersion should be fixed now.
Feel free to re-open if the problem persists with the last version and/or create new issues if you a get different error.

Can you share the output of uname -a please?

@spidy0x0 it looks like the patch version is missing from the kernel release 🤔
The program expects uname --kernel-release returns a X.Y.Z version followed by optional special chars.
