Changing my build.gradle to shown below worked.

buildscript {
    repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:1.5.0'
}
}

allprojects {
    repositories {
        jcenter()
    }
}

    delete rootProject.buildDir
}

DO NOT change your package source to http instead of https. Stop using these workarounds and fix the root cause.

Do you want to have a driveby exploit in your app? Because that's how you get a driveby exploit in your app!

The source of this problem Certificate Authority keystore. Somehow dpkg seems to try to build the Java keystore (/etc/ssl/certs/java/cacerts) before it actually installs Java, which the the tool to build the store requires. The result is an empty store:

To fix this, properly build the keystore with all trusted CA certificates.

Run this with sudo:

sudo rm /etc/ssl/certs/java/cacerts
sudo /var/lib/dpkg/info/ca-certificates-java.postinst configure

You should see a long list of added certificates (*.pem) and finally a “done”.

Re-sync the project using gradle, and all will download. Don't forget to turn off the http override if you've set it!

Answer 5

It's a dumb answer, but what fixed this for me was restarting Android Studio.

I was using Charles Proxy off and on, I suspect that had something to do with the cause of the error. Closed the proxy and restarted android studio, and it worked. Figured I would post because sometimes the answer is so simple we forget to even try it.

Answer 6

This was the solution that worked for me. Posting here in case it helps someone.

Gradle version was not correct in project build.gradle file.

I had

classpath 'com.android.tools.build:gradle:1.0.0'

but this needed to be

classpath 'com.android.tools.build:gradle:2.1.0'

Note:
This should be updated to the newest version of gradle tools which can be found here Android Studio also recommends the latest plugin version.
