I don’t know how to install these packages. I understood that the “ngspice” model is made by each semiconductor manufacturer in a different way. How do you enter the “spice codes” in KICAD?

‘’‘dpkg-query: package ‘libngspice0’ is not installed’’’
Haw install this ?

Please do not occupy an old thread. Open a new thread instead.

I do not understand your question. What is your operating system? What do you want to do? What did you do to get this output which you have shown?

Dpkg is a Debian distro family utility and would not be appropriate on Fedora. As Holger said, say what is it you’re trying to do, rather than attempt inappropriate instructions.

Thanks for the answer. I have Fedora and I wanted to load some ngspice libraries to see how the simulation tool works. I don’t know where these spice libraries are and I don’t know how to install them. Instead, I managed to load 3D libraries according to the instructions on the official website Kikad
Sorry, I won’t open this topic again

You can continue this thread, I split it off. Maybe someone who knows Fedora can say which Fedora packages to install.

To installl ngspice just do

sudo dnf install ngspice

(which should automatically install dependencies like libngspice as well)

The docker errors are unrelated, you seem to have some broken docker repos enabled.

Do not use dpkg on Fedora.

Unfortunately I have no experience in actually using ngspice, but for Fedora related problems I should be able to help.

libngspice is not a dependency to plain ngspice, but to KiCad.

libngspice is installed together with KiCad. However it may not be complete (code models are missing). So install plain ngspice in addition.

See here: Fedora KiCad/Eeschema/ngspice installation is incomplete
