Errors installing remnux as a addon about cast

[ekristen]

This looks to be a bug in the remux saltstack states at first glance but I'd have to dig a bit deeper to know for sure. Unfortunately I don't have much time at the moment to do this, I can try and find some time in the coming week.

It looks like some variables python and python3_version aren't being populated properly.

Hi @tompolth , can you tell me what version of Ubuntu you're attempting to install REMnux on? The initial error in the log you provided identifies an inability to map the os_rel variable. At this time, only Ubuntu Focal is supported for REMnux, with incoming support for Jammy. While the current state files do provide the "ability" to install on Bionic, the full installation of REMnux is not currently supported on this version.

Given that Python 3.8 is the default version on Ubuntu Focal, and 3.10 is Ubuntu Jammy, the issue is likely due to the OS version, because the first error in the log file you provided is:

Since there are errors here related to cpython39, I want to make sure we determine the version you're running the installation on before we can provide a resolution. If this issue continues, please open an issue on the REMnux Issues Page so we can accurately track the issue there. Ultimately, based on the information you provided, this isn't actually a Cast issue.

You're right. I have tried to install it in the Jammy version instead of Focal. I guess I'll have to repeat the process going back to 20.04. is it so?

[digitalsleuth]

Hi @tompolth , yes, for the time being Focal is the latest OS to be supported for REMnux. There are a few applications used in REMnux which do not yet support, or have not yet been built for Jammy, so we are working to get those applications up to date.

[tompolth]

Let's wait then. In the meantime I'll try it with Focal.

Many thanks
