Hello @eduardo_reis 

The error "Error downloading the following files: mcusAds.json.tmp (Not available)" in STM32CubeIDE 1.19.0 usually occurs due to network connectivity issues, firewall or proxy restrictions, or temporary server unavailability when the IDE tries to download necessary package files. To resolve this, make sure your internet connection is stable, configure any proxy settings within the IDE if needed, and check that no firewall or antivirus is blocking the download. Clearing the IDE’s cache (.stm32cubeide) can also help. Running the IDE with administrator privileges may resolve permission-related problems.

Hello @Ghofrane GSOURI thank you for your response. I don't think the first part of the answer (network connection / firewall, etc) was cause of the issue I have. But, very likely it was what you said in the second part, the admin privileges. I originally had installed stm32ide with the generic linux install without using `sudo`. After hitting this issue, I uninstalled everything and installed the IDE using the debian installer with `sudo`. The issue did not occur.

 

Thank you for your feedback.
