Using rpy2 to install additional packages failing from jupyter lab

Question

I am trying to call R from within some python code using the rpy2 library. I need to use non-base packages, but keep on running into the following hiccup. Thanks for considering! Most of the code is copy-pasted from the manual.

import rpy2
import rpy2.robjects as robjects
from rpy2.robjects.packages import importr

# import rpy2's package module
import rpy2.robjects.packages as rpackages

base = importr('base')

# import R's utility package

utils = rpackages.importr('utils')

# select a mirror for R packages
utils.chooseCRANmirror(ind=1) # select the first mirror in the list


# R package names
packnames = ('pROC', 'bootLR')

# R vector of strings
from rpy2.robjects.vectors import StrVector

# Selectively install what needs to be install.
# We are fancy, just because we can.
names_to_install = [x for x in packnames if not rpackages.isinstalled(x)]
if len(names_to_install) > 0:
    utils.install_packages(StrVector(names_to_install))
    
importr('bootLR')

Gives error
