Arm Development Studio 2020.0: un.security.provider.certpath.SunCertPathBuilderException: Unable to find valid certification path to requested target

George_

I tried to download the CMSIS pack but get the error:

javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I find out it's the ssh certificate issue, but how can I fix this? I also find that the studio has the jave itself under the install directory, maybe I should import the certificate to the xxx\Arm\Development Studio 2020.0\sw\java\lib\security\cacerts, but it make no sense just I meet this issue if the cert is missing in this file. Maybe I should try the old version?

My configuration is:

win10 1903 18362.720

Arm Development Studio 2020.0

Anyone know how to fix this?

Regards, George.
