How can I repair error resolve package not found: yosys It is sky130 install on ubuntu

Check the dependencies required to install sky130 pdk. Maybe

sudo apt-get install yosys

will resolve it

I think that there is a bug in conda setup. There is a branch dedicated to fix the issue. (https://github.com/google/skywater-pdk/tree/fix-conda-channels). For what is worth the way I managed to fix that on my local copy was to: 1. source open_pdks/sources/sky130-pdk/env/conda/bin/activate 2. conda install --name skywater-pdk-scripts -c litex-hub yosys Then I re-ran make.

@SimonM try these once: https://installati.one/install-yosys-ubuntu-20-04/
