Android SDK installation issue - Peer not authenticated

Question

I am trying to install the Android SDK and I get the following error in the SDK Manager Logs -

Fetching https://dl-ssl.google.com/android/repository/addons_list-1.xml Failed to fetch URL https://dl-ssl.google.com/android/repository/addons_list-1.xml, reason: peer not authenticated Fetched Add-ons List successfully Fetching URL: https://dl-ssl.google.com/android/repository/repository-5.xml Failed to fetch URL https://dl-ssl.google.com/android/repository/repository-5.xml, reason: peer not authenticated Done loading packages. 

The error has something to do with proxy settings etc. I am running Ubuntu 11.10 and I had installed the SDK comfortably on the same setup yesterday.

Answer 1

As a workaround, I enabled the "Force https://... sources to be fetched using http://..." setting in the SDK Manager Tools > Options menu.

If you use Android Studio instead of the standalone SDK Manager, Choose "SDK Update Sites" in the "Android SDK" settings and click the checkbox in the lower part of the screen.

That seems to help. I suspect it is a server side problem, but I'm not sure about that.

Edit: Please note that using http instead of https is not really the best idea! In the worst case, a man-in-the-middle attack could inject malicious code into your Android SDK libraries that ends up in your APK. That's why it's called a workaround :)

Answer 2

In my particular case, I had the "Peer not authenticated" error on my android device as the system time on my device was set in the past, no issues with your system time?

Thanks to this page for pointing out the seemingly obvious... :)
