Hello,

I am trying to simulate a filter for a friend, but I am having problems with the potmeter:

There seems to be some files that can not be found.
I am running LTspice with WINE on my linux PC.

I have the following paths in settings:

Hello,

I tried both suggestions, but still I get the failures.
I am running LTspice 24.1.5.

There is a potmeter.sub available:

Hi,
I am running LTS XVIIx86 and XVIIx64 on Win10 32/64 bit.
We need a Linux user.
I know there are differences between Win and Linux with LTS

My version of spice didn't come with a pot model either. Put both attached files in "User files" directory and add ".include potentiometer.sub" directive.

Screenshot from 2025-03-17 12-25-39.png

Versions:
LTspice 24.1.5
Wine-9.0 (Ubuntu 9.0~repack-4build3)

On my machine, the folder "C:\users\dan\Documents\LTspice" shown in the screenshot is the virtual drive path for "/home/dan/.wine/drive_c/users/dan/Documents/LTspice". The symbolic link for the path is "/home/dan/Documents/LTspice" which is where I put my files.

Hello,

I found the error.
I installed LTspice for everyone, so the library needs to be in an other place:
C:\users\bert\Local Settings\Application Data\LTspice

I have an picture of the working simulation:
