[NTG-context] circuitikz module seems broken

3 Dec 2021

      Dear List!

I’ve been struggeling with the circuitikz module since my upgrade to LMTX.

The following test of installation failed, running file 

circuitikz-context.tex in ../modules/t-tikz/ directory

A simple example to test the installation.
