I just updated to etm 3.06 by running: pip3 install -U etm-dgraham. Seems to run fine but I don't think it is installed in a virtual environment. It is simply in my home/etm-pypi directory. I get to it by navigating to that directory and telling file manager Dolphin to "open terminal here." I then run etm4 and etm opens.
Should I see if I can re-install it in a virtual environment? I would rather not unless it is important.
