Current Behavior



When I type try to run conda update -n base conda, conda hung for around 20-minutes on 'Solving environment' and then returned a package plan that did not include an updated version of conda. The package plan that was returned is provided below.



The package plan that was returned is as follows:

Proceed ([y]/n)? n







NOTE: the conda version I have installed is 4.5.11 - I'm not sure if this is the most recent version and haven't been able to find a command or resource (other than conda update conda) to check what the most recent version is. I also had a similar problem when trying to conda install websocket-client when websocket client was already installed - I wonder if the current version of conda has trouble when the most recent version of a package is already installed.



NOTE 2: conda update --all solved the environment in a reasonable amount of time (~1 min - I didn't time it precisely).



Steps to Reproduce




conda update -n base conda



As I mentioned above, conda install websocket-client also hung at 'Solving environment' - I already had websocket-client version 0.53.0 installed when I tried to run the install command



Expected Behavior



Conda should either:
1. If the most recent version is installed, conda should promptly inform the user that an update isn't needed.
1. If a newer version is available, I'd expect Conda to solve the environment in a shorter period of time. I think that less than 1-2 minutes would be reasonable - 20+ minutes is too long

    Current Behavior



    When I type try to run conda update -n base conda, conda hung for around 20-minutes on 'Solving environment' and then returned a package plan that did not include an updated version of conda. The package plan that was returned is provided below.



    The package plan that was returned is as follows:

    Proceed ([y]/n)? n







    NOTE: the conda version I have installed is 4.5.11 - I'm not sure if this is the most recent version and haven't been able to find a command or resource (other than conda update conda) to check what the most recent version is. I also had a similar problem when trying to conda install websocket-client when websocket client was already installed - I wonder if the current version of conda has trouble when the most recent version of a package is already installed.



    NOTE 2: conda update --all solved the environment in a reasonable amount of time (~1 min - I didn't time it precisely).



    Steps to Reproduce




    conda update -n base conda



    As I mentioned above, conda install websocket-client also hung at 'Solving environment' - I already had websocket-client version 0.53.0 installed when I tried to run the install command



    Expected Behavior



    Conda should either:
    1. If the most recent version is installed, conda should promptly inform the user that an update isn't needed.
    1. If a newer version is available, I'd expect Conda to solve the environment in a shorter period of time. I think that less than 1-2 minutes would be reasonable - 20+ minutes is too long

      NOTE:
      I'm duplicating this post because the question has been up on the conda github page for ~6-days with no response. The original link is here:

      Current Behavior



      When I type try to run conda update -n base conda, conda hung for around 20-minutes on 'Solving environment' and then returned a package plan that did not include an updated version of conda. The package plan that was returned is provided below.



      The package plan that was returned is as follows:



      environment location: C:UsersjmattAnaconda3
      added / updated specs:
      - conda


      The following packages will be downloaded:

      Proceed ([y]/n)? n







      NOTE: the conda version I have installed is 4.5.11 - I'm not sure if this is the most recent version and haven't been able to find a command or resource (other than conda update conda) to check what the most recent version is. I also had a similar problem when trying to conda install websocket-client when websocket client was already installed - I wonder if the current version of conda has trouble when the most recent version of a package is already installed.



      NOTE 2: conda update --all solved the environment in a reasonable amount of time (~1 min - I didn't time it precisely).



      Steps to Reproduce




      conda update -n base conda



      As I mentioned above, conda install websocket-client also hung at 'Solving environment' - I already had websocket-client version 0.53.0 installed when I tried to run the install command



      Expected Behavior



      Conda should either:
      1. If the most recent version is installed, conda should promptly inform the user that an update isn't needed.
      1. If a newer version is available, I'd expect Conda to solve the environment in a shorter period of time. I think that less than 1-2 minutes would be reasonable - 20+ minutes is too long

      Current Behavior



      When I type try to run conda update -n base conda, conda hung for around 20-minutes on 'Solving environment' and then returned a package plan that did not include an updated version of conda. The package plan that was returned is provided below.



      The package plan that was returned is as follows:

      Proceed ([y]/n)? n







      NOTE: the conda version I have installed is 4.5.11 - I'm not sure if this is the most recent version and haven't been able to find a command or resource (other than conda update conda) to check what the most recent version is. I also had a similar problem when trying to conda install websocket-client when websocket client was already installed - I wonder if the current version of conda has trouble when the most recent version of a package is already installed.



      NOTE 2: conda update --all solved the environment in a reasonable amount of time (~1 min - I didn't time it precisely).



      Steps to Reproduce




      conda update -n base conda



      As I mentioned above, conda install websocket-client also hung at 'Solving environment' - I already had websocket-client version 0.53.0 installed when I tried to run the install command



      Expected Behavior



      Conda should either:
      1. If the most recent version is installed, conda should promptly inform the user that an update isn't needed.
      1. If a newer version is available, I'd expect Conda to solve the environment in a shorter period of time. I think that less than 1-2 minutes would be reasonable - 20+ minutes is too long
