Comment 8 for bug 1806265

Problem is definitely related to changes in Oracle licensing for Java, they made a change on April 16, 2019 to their licensing which requires a signature in order to download the DEB file online. There are articles on AskUbuntu regarding this issue related to the webupd8 team PPA:

2 http://www.webupd8.org/2012/09/install-oracle-java-8-in-ubuntu-via-ppa.html

From Synaptic Package Manager broken filter:

E: /var/cache/apt/archives/openjdk-8-jre-headless_8u212-b03-0ubuntu1.18.04.1_amd64.deb: trying to overwrite shared '/etc/java-8-openjdk/calendars.properties', which is different from other instances of package openjdk-8-jre-headless:amd64

Partly fixed but still need to resolve this problem with Oracle.
