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!
