Trouble with update conda

[Arnaud Mounier]

Hi there,

I need to update conda and I launch this command :

$> conda update -n base conda -c defaults

but the conda system wants to remove all this packages :

The following packages will be REMOVED:

  argon2-cffi-21.1.0-py36h8f6f2f9_0
  backports-1.0-py_2
  backports.functools_lru_cache-1.6.4-pyhd8ed1ab_0
  html5lib-1.1-pyh9f0ad1d_0
  importlib-metadata-4.5.0-py36h5fab9bb_0
  jupyterlab_pygments-0.1.2-pyh9f0ad1d_0
  libgomp-11.2.0-h1d223b6_14
  nbclient-0.5.9-pyhd8ed1ab_0
  pthread-stubs-0.4-h36c2ea0_1001
  pyct-core-0.4.6-py_0
  sphinxcontrib-applehelp-1.0.2-py_0
  sphinxcontrib-devhelp-1.0.2-py_0
  sphinxcontrib-htmlhelp-2.0.0-pyhd8ed1ab_0
  sphinxcontrib-jsmath-1.0.1-py_0
  sphinxcontrib-qthelp-1.0.3-py_0
  sphinxcontrib-serializinghtml-1.1.5-pyhd8ed1ab_1
  typing_extensions-4.1.1-pyha770c72_0
  zipp-3.6.0-pyhd8ed1ab_0

and I want to know if it safe or not, in particular for this package :

nbclient-0.5.9-pyhd8ed1ab_0

because I don't want to break my jupyterhub system.

thank you very much,

Arnome.
