Just attempted updating from 1.6.1 to 1.70. Got an assert error. I performed an update of the pi o/s and tried updating again. Got same assert failure.
Still Getting this error after updating Pip to latest version.
Traceback (most recent call last):

The update did not finish successfully. Please consult
plugin_softwareupdate_console.log for details.
It might be easier for you to open your own post to fix the problem. Are you sure you updated pip inside the virutal environment? Anyway, open a new post, upload a systeminfo bundle and the log from the failed install.
