Issue downloading authlib for "feed the beast"/minecraft or any other person having "java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty" issue
The problem is the file /etc/ssl/certs/java/cacerts is either create or does not exist. If it exists delete it and do the following: - purge the ca-certificates and ca-certificates-java packages: sudo dpkg -P --force-depends ca-certificates ca-certificates-java - reinstall these packages: sudo apt-get -f install After this was done my issue was solved I found the solution in: https://bugs.launchpad.net/ubuntu/+source/ca-certificates-java/+bug/289934
