So now I'm in this infinite a loop.

Please help me with running this tool.

i have the same issue

[D-VR]

The reason it doesn't work is because undervolt is only installed for the user.

A dirty fix would be to run the pip install using sudo.

You could maybe also create a symlink at /usr/local/bin/undervolt pointing to your user copy

I ran into this same issue and spent way too long looking for a solution, but it's actually easy. Just install with:

pip3 install undervolt

Then you can run the python package directly from the folder it installed to using sudo. For me it's:

sudo python3 ~/.local/lib/python3.10/site-packages/undervolt.py

[momincks]

install with sudo su

sudo su
pip install undervolt
undervolt --read
