Error installing STMicroelectronics.button_part_drivers.2.0.0 pack

Thank you @B.Montanari  for the complete guide. Unfortunately on my computer the project is not created as packs can't be downloaded, error is the following (in this case for button pack):

Error installing STMicroelectronics.button_part_drivers.2.0.0 pack

Could not save pack of pack-URL: https://developer.st.com/st-pack-server/api/v1/pack/STMicroelectronics.button_part_drivers.2.0.0.pack, got: Unsupported `GLOBAL_AGENT.HTTP_PROXY` configuration value: URL protocol must be "http:".

 

I'm behind a proxy (set at system level), and if I use the URL listed I'm able to download and manually install the pack. I tried setting proxy information on MX2 as IP:port with no result.

Is there a way to solve this?

Found the reason of my issue. I had Windows system variables HTTP_PROXY and HTTPS_PROXY set without "http://" in front of IP. Once corrected everything worked.

Hi @paolog 

In this case, what you need is to configure a proxy or a certificate to be able to access the servers and download packages.

  • Get your certificate from your company IT or company portal.
  • Place it under C:\certificate, for example.
  • Add the Windows environment variable NODE_EXTRA_CA_CERTS with the path to this certificate file. (Make sure that the path has no quotes.)

  • Finally, restart STM32CubeMX2.

You can also refer to this article for more details on: How to configure the proxy or certificate

Hi @Oussama_TROUDI , thank you for your reply.

I followed the directions on the above link as much as possible, as we don't use Visual Studio Code. We installed the certificate, defined the variable NODE_EXTRA_CA_CERTS to point to the certificate file, and defined proxy in MX2 as "http://Proxy-address:port". But the error is still there.

Should system variable GLOBAL_AGENT_HTTP_PROXY be defined?

Any other option to solve this?

Thank you.
