Open-source Languages & Tools for z/OS

Hi Gadi,

You do not need a support contract with Rocket to download and install cURL.  Only you will not be able to get the latest binaries with the latest security fixes.  The error is stemming from the fact that you chose the conda channel server option that is reserved for customers on support contract.  I think if you re-read the install instructions more carefully you will see instructions describing the fact that there are two conda channel servers - one free for all, and one reserved for customers.  Now that you have chosen the wrong option you will I think need to edit your conda.config file to point to the free channel server hosted by anaconda.org.

Best

Hi Peter,

Thanks for your reply.

I am trying the command:

conda install -c https://conda.anaconda.org/zoss-appdev curl

And I get:

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://conda.anaconda.org/zoss-appdev/zos-z/repodata.json> 

Could this be happening because a firewall is blocking my access?

I'm waiting for the firewall admins to give access to conda.anaconda.org

That's true, if there is a firewall, it is almost certainly the root cause.

Hi all,

The firewall people did their thing, and now I'm getting:

(base) bash-5.1# conda install -c https://conda.anaconda.org/zoss-appdev curl   
Collecting package metadata (repodata.json):   failed

Resources of type {resource_type} cannot be accessed by unauthenticated users.  

What can I do to tell conda to only look at conda.anaconda.org?

Hi Gabi,

Most likely you choose to use a private channel during the installation of the miniconda and you have condaserver.rocketsoftware.com in your .condarc now. To confirm that try conda config --show-sources command and delete the line with channel_alias from appropriate .condarc

Thanks,
Alexander

Gadi Ben-Avi posted 03-15-2023 10:25

Hi All,

Using conda config --show-sources showed me that I had two .condarc files, one in the conda root directory, and another in my home directory. 

I deleted the one in my home directory.

now, when I run the install command, I get:

(base) bash-5.1# conda install -c https://conda.anaconda.org/zoss-appdev curl   
Collecting package metadata (repodata.json):   failed

HTTP errors are often intermittent, and a simple retry will get you on your way.
                                                                                
If your current network has https://www.anaconda.com blocked, please file       
a support request with your network engineering team.                           
                                                                                
'https//repo.anaconda.com/pkgs/main/zos-z'

What is missing now?

Gadi

Hi,
looks like repo.anaconda.com is blocked also by your firewall, it's the default anaconda repository. You can override channels in conda install command.

conda install -c https://conda.anaconda.org/zoss-appdev curl --override-channels

Gadi Ben-Avi posted 03-15-2023 11:56

HI Alexander,

When I issued the command:

conda install -c https://conda.anaconda.org/zoss-appdev curl --override-channels

I got:

<a.anaconda.org/zoss-appdev curl --override-channels                            
Collecting package metadata (repodata.json):   failed                           
                                                                                
UnavailableInvalidChannel: HTTP 404 NOT FOUND for channel conda.anaconda.org/zos
s-appdev <https://conda.anaconda.org/conda.anaconda.org/zoss-appdev>            
                                                                                
The channel is not accessible or is invalid.                                    
                                                                                
You will need to adjust your conda configuration to proceed.                    
Use `conda config --show channels` to view your configuration's current state,  
and use `conda config --show-sources` to view config file locations.

I issued the command and got:

(base) bash-5.1# conda config --show channels    
channels:                                        
  - r

show_channel_urls: True                          
                                                 
(base) bash-5.1# conda config --get              
--add channels 'defaults'   # lowest priority    
--add channels 'r'   # highest priority          
--set show_channel_urls True

Are you sure about the correctness of the command which you are trying to run?
I see "<a.anaconda.org/zoss-appdev curl --override-channels" as part of command and conda.anaconda.org/conda.anaconda.org in conda error output.

so looks like you a trying to run something like

conda install -c https://conda.anaconda.org/conda.anaconda.org/zoss-appdev curl --override-channels
this is wrong channel, please use the command from my previous post. 

Thanks,
Alex

Hi Alexander,

I noticed that the problem was accessing https://conda.anaconda.org/conda.anaconda.org/zoss-appdev

I issued this command conda install -c zoss-appdev curl --override-channels, and it worked and installed curl. 

Thanks to everyone for your help
