Downloading: https://s3.amazonaws.com/Minecraft.Download/launcher/launcher.pack.lzma Exception: javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-emptyThis just means that your ssl certs are not correct for the java version you have installed. In my case I was also getting the following error:
$ ls -l /etc/ssl/certs/java/cacerts ls: cannot access /etc/ssl/certs/java/cacerts: No such file or directorySo this comman fixed my issue:
scp -pr root@a_different_box_with_working_certs:/etc/ssl/certs/java/cacerts /etc/ssl/certs/java/.Hope that helps you too.
