File signature verification failed on package_index.json

[heyyprateek]

Has anyone programmed XMC microcontroller by Infineon Technologies using Arduino IDE?

I tried as per the steps given in the GitHub repo of Infineon. Below is the link of the same:

https://github.com/Infineon/XMC-for-Arduino/wiki/Implementation-in-Arduino-IDE

After I copied the .json url in the preferences, I am getting following error:

http://downloads.arduino.cc/packages/package_index.json file signature verification failed. File ignored.

Index error: could not find referenced tool name=arm-none-eabi-gcc version=4.8.3-2014q1 packager=arduino

What can be a possible solution for it? I am running Arduino IDE 1.8.5 on Windows 10. Is this has anything to do with it?

Hi @webstone13 ,
the problem here is that http://downloads.arduino.cc/packages/package_index.json gets ignored due to a certificate error. I am sure that the certificate is ok so the problem must be somewhere else.
Which IDE version are you running? You can try removing manually the cached jsons in

• C://Users/youruser/AppData/Arduino15/ if you are on Windows
• /Users/youruser/Library/Arduino15/ if you are on Mac
• ~/.arduino15/ if you are on Linux

and restart the library manager.

Hi @facchinm,
I am running Arduino IDE 1.8.5 on Windows 10. What are cached jsons? Are they same as .tmp file in Arduino15 folder. If yes, I have already tried that and it didn't work.

Thanks for the help.

[facchinm]

You need to remove all .sig , .json and .tmp in that folder to make sure that everything gets redownloaded. To make sure that nothing happens in the background, keep the IDE closed while doing it.
If it doesn't solve the issue it would help if you could attach here package_index.json and package_index.json.sig so I can check if there is something corrupted, thanks.

@facchinm
Didn't work. Please find the .json file in the link below.
https://github.com/Infineon/Assets/releases/download/current/package_infineon_index.json

[facchinm]

Sorry if I was not clear enough, the problem seems related with Arduino-provided json (the default one called package_index.json). I need you to attach a zip containing the (json and sig) files that are bing downloaded to your PC (in the Arduino15 folder). Thanks

json files.zip

Dear @facchinm
Please find attached all the .json files in Arduino15 folder.

[facchinm]

Does your Arduino15 folder only contained that files? No other .json or .sig? I'm starting to think that it could be a problem related with a very strict antivirus running in the background and deleting random files it thinks could harm the system. Try adding the Arduino15 folder to its whitelist and/or check if the needed files (namely package_index.json and package_index.json.sig) has been quarantined.

Dear @facchinm
Thanks for your help. I tried doing the same in portbale version of Arduino IDE and it works perfectly fine there.
I don't know what the problem was in the original version but somehow it is working now.

What you are suggesting maybe true. It may be possible as I am trying this on my office PC which is quite secured.

Thanks anyway.

I'm closing the issue in the meantime, changing the title so it may be easier to find if someone else encounters it. Thanks for your time.

Please open the issue again. I get this message on two different computers one on version 1.8.4 and one on 1.8.5: "http://downloads.arduino.cc/packages/package_index.json file signature verification failed. File ignored."

I deleted the 1.8.5 version's Arduino15 directory and reinstalled the IDE a few times without success.
