Can't execute "hetzner-k3s create --config cluster_config.yaml" - error Unhandled exception: SSL_CTX_new: error: [...] (OpenSSL::Error)

[Linutux]

I Installed all required packages ("sudo dnf install libssh2 libevent libyaml pcre gmp gc-devel"), created a cluster_config.yaml and executed "hetzner-k3s create --config cluster_config.yaml".

I got the following error:

Validating configuration...Unhandled exception: SSL_CTX_new: error:030000A9:digital envelope routines::unknown option (OpenSSL::Error)

Can you please help me?

I'm sorry for the lack of replies. I was sick and then very busy with the day job. Did you figure out what was the problem in the end?

[Linutux]

Nö, I have not tried again.

I switched from Fedora to Ubuntu lately and will try again...

[rsidhaarth]

I am getting the same error, I am using Ubuntu 22.04

I have installed these dependencies

sudo apt install libssh2-1 && \ sudo apt install libevent-dev && \ sudo apt install libyaml-dev && \ sudo apt install libpcre3 libpcre3-dev

am I missing something?

[vitobotta]

@Linutux @rsidhaarth I have upgraded the SSH2 shard in main, can you try again? I haven't released this change yet as I want to merge other changes first.

I had the same error on Fedora 40.
When I built the app from the source code from the main branch, the error is no longer there.

I haven't found a description about the steps required to build the app locally, so I'll paste it here, hope you don't mind.

Hi @konczdam , thanks for confirming that the problem is fixed in main! I am still working on finalising v2.0.0, which will include this together with a lot of other stuff.
