How to choose an Ubuntu version

Binder
#1

Hi All,

Is it possible to choose a specific Ubuntu version for a new binder imported from a github repo?
I am getting an Ubuntu bionic (18.04) machine, but a package I need (libngspice0) is only available on focal (20.04) and groovy (20.10).

As an alternative, can I include the dynamic library in the repository and point LD_LIBRARY_PATH to it, or do you foresee any problems with this approach?

Thanks

Hi! Unfortunately, I don’t think this feature is currently available unless you provide your own Dockerfile like this example https://github.com/binder-examples/minimal-dockerfile

Thanks for your help.

It turns out that ngspice is provided by conda, so you can use the environment.yml
to set it up.
I wasn’t expecting it because ngspice is not written in python.

I thought I should mention it here in case someone else tries to use ngspice and bumps into this topic.

Ah, it’s a common misconception that conda is for python only - it’s a generic package manager. Glad you found a solution and thank you for updating this post!
