If you are trying to update your Anaconda version to a new one  you ll notice that running the new installer wouldn t work  as it complains the installation directory is non-empty   So you should use conda to upgrade as detailed by the official docs   conda update conda conda update anaconda    In Windows  if you made a  for all users  installation  it might be necessary to run from an Anaconda prompt with Administrator privileges     This prevents the error      ERROR conda core link  execute 502   An error occurred while uninstalling package  defaults  conda-4 5 4-py36 0     PermissionError 13   Access is denied

Open  command or conda prompt  and run   conda update conda conda update anaconda   It s a good idea to run both command twice  one after the other  to be sure that all the basic files are updated   This should put you back on the latest  releases   which contains packages that are selected by the people at Continuum to work well together   If you want the last version of each package run  this can lead to an unstable environment    conda update --all    Hope this helps   Sources    https   docs anaconda com anaconda install update-version https   github com conda conda issues 1414 issuecomment-119071154

Use  conda create -n py37 -c anaconda anaconda 5 3 1 conda env export -n py37 --file env yaml  Locate the env yaml file in C  Windows System32 and run the cmd as administrator  conda env update -n root -f env yaml  Then it works

If you have trouble to get e g  from 3 3 x to 4 x  conda update conda  does not work  to get to the next version  than try it more specific like so   conda install conda 4 0  or conda install anaconda 4 0    https   www anaconda com blog developer-blog anaconda-4-release   You should know what you do  because conda could break due to the forced installation  If you would like to get more flexibility security you could use pkg-manager like nix -pkgs    with nix-shell    NixOS

This is what the official Anaconda documentation recommends  conda update conda conda update anaconda 2020 07  If the second line throws an error  typo in the documentation   this worked here  conda install anaconda 2020 07   You can find all version specifier here   The command will update to a specific release of the Anaconda meta-package  This is  IMHO  what 95  of Anaconda users want  Simply upgrading to the latest version of the Anaconda meta-package  put together and tested by the Anaconda Distributors  and not caring about the update status of individual packages  which would be issued by conda update --all

Here s the best practice  in my humble experience   Selecting these four packages will also update all other dependencies to the appropriate versions that will help you keep your environment consistent  The latter is a common problem others have expressed in earlier responses  This solution doesn t need the terminal

To update your installed version to the latest version  say 2019 07  run  conda install anaconda 2019 07  In most cases  this method can meet your needs and avoid dependency problems

root is the old  pre-conda 4 4  name for the main environment  after conda 4 4  it was renamed to be base   source  What 95  of people actually want In most cases what you want to do when you say that you want to update Anaconda is to execute the command  conda update --all   But this should be preceeded by conda update -n base conda so you have the latest conda version installed  This will update all packages in the current environment to the latest version -- with the small print being that it may use an older version of some packages in order to satisfy dependency constraints  often this won t be necessary and when it is necessary the package plan solver will do its best to minimize the impact   This needs to be executed from the command line  and the best way to get there is from Anaconda Navigator  then the  quot Environments quot  tab  then click on the triangle beside the base environment  selecting  quot Open Terminal quot    This operation will only update the one selected environment  in this case  the base environment    If you have other environments you d like to update you can repeat the process above  but first click on the environment   When it is selected there is a triangular marker on the right  see image above  step 3    Or from the command line you can provide the environment name  -n envname  or path  -p  path to env   for example to update your dspyr environment from the screenshot above  conda update -n dspyr --all  Update individual packages If you are only interested in updating an individual package then simply click on the blue arrow or blue version number in Navigator  e g  for astroid or astropy in the screenshot above  and this will tag those packages for an upgrade   When you are done you need to click the  quot Apply quot  button   Or from the command line  conda update astroid astropy  Updating just the packages in the standard Anaconda Distribution If you don t care about package versions and just want  quot the latest set of all packages in the standard Anaconda Distribution  so long as they work together quot   then you should take a look at this gist  Why updating the Anaconda package is almost always a bad idea In most cases updating the Anaconda package in the package list will have a surprising result  you may actually downgrade many packages  in fact  this is likely if it indicates the version as custom    The gist above provides details  Leverage conda environments Your base environment is probably not a good place to try and manage an exact set of packages  it is going to be a dynamic working space with new packages installed and packages randomly updated   If you need an exact set of packages then create a conda environment to hold them   Thanks to the conda package cache and the way file linking is used doing this is typically i  fast and ii  consumes very little additional disk space   E g  conda create -n myspecialenv -c bioconda -c conda-forge python 3 5 pandas beautifulsoup seaborn nltk  The conda documentation has more details and examples  pip  PyPI  and setuptools  None of this is going to help with updating packages that have been installed from PyPI via pip or any packages installed using python setup py install   conda list will give you some hints about the pip-based Python packages you have in an environment  but it won t do anything special to update them  Commercial use of Anaconda or Anaconda Enterprise It is pretty much exactly the same story  with the exception that you may not be able to update the base environment if it was installed by someone else  say to  opt anaconda latest    If you re not able to update the environments you are using you should be able to clone and then update  conda create -n myenv --clone base conda update -n myenv --all
