ArcGIS Server 11.3 Python Conda Proup Command Issues

AlexWardle_IDITS — Tue, 28 Oct 2025 17:07:03 GMT

Working on doing an upgrade of a python environment from ArcGIS 10.9.1 to 11.3 using the conda proup command and this ESRI article. I have made sure that all permissions are properly set in the environment and running the command prompt as Administrator.

We are running Arc GIS Enterprise 11.3 on Windows Server 2019.

Are there error logs that we should be looking at. Any Ideas on what to try next?

This is what I am getting when running the command.

Well, in Pro you can't create a clone of the python env at the "C:\\Program Files\. . ." location because that location is always write protected.

I would set up something like a "C:\\pyclone\envs\ . . ." directory, making sure the ArcGIS Server service account has read write permissions to the directory and then clone the default environment to that directory.

Then you can activate the new environment, run any conda updates and install any custom libraries...

Hi @AlexWardle_IDITS,

Make sure you're executing the command in an elevated command prompt or PowerShell window as an Administraror. Also, try manually creating the environment to isolate the issue to test the Conda Env.

So I have copied the environment from the program files folder and put it in a separate folder called E:\pyclone\envs and it is still doing the same thing. I have verified that the gis service account has full permissions to this directory. I am running CMD as administrator and I have also tried it from the Python 3 Command Prompt as Administrator as well.

Well I think I found the issue while creating a new test env, looks to be an SSL Certificate issue. The conda.anaconda.org website goes through our firewall with ssl inspection. is there a command that I can use to specify our root cert that the firewall uses?

CondaSSLError: Encountered an SSL error. Most likely a certificate verification issue. Exception: HTTPSConnectionPool(host='conda.anaconda.org', port=443): Max retries exceeded with url: /esri/win-64/c-ares-1.19.1-0.conda (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate in certificate chain (_ssl.c:1006)')))

I fixed the issue, for those with SSL Inspection on the firewall. I first copied our root ca cert and put it in the following file "C:\Program Files\ArcGIS\Server\framework\runtime\ArcGIS\bin\Python\envs\arcgispro-py3\Lib\site-packages\certifi\cacert.pem"

After adding the Cert to that file in the Command Prompt Ran this command: conda config --set ssl_verify "C:\Program Files\ArcGIS\Server\framework\runtime\ArcGIS\bin\Python\envs\arcgispro-py3\Lib\site-packages\certifi\cacert.pem"

I then was able to create a test environment to make sure the SSL Verify was working as expected.
