Planck binaries are now available for Ubuntu 18.04 LTS Bionic Beaver.

Just a note on the 18.04 install of lein. After installing default-jre and default-jdk, lein repl has security stack dumps from trying to retrieve the jar dependencies. This doesn't happen on 16.04.

Right. As far as I can tell, Canonical surprisingly screwed up the Java installation in Ubuntu 18.04.

(The certificate store you get is messed up.)
