I suspect this bug may be related to an install of Oracle's Java package for Ubuntu which I installed using Oracle's deb package. This didn't cause problems for months until I suddenly got the error while running regular packaged updates using the normal user interface and standard Ubuntu tools. I can no longer use apt-get, synaptic or any other deb package installer and I'm hesitant to try to fix things manually by removing files. This latest occurrence was running "sudo apt-get install -f"
Here is the output copied from my terminal session: ========= gnace@gn-limbo:~$ sudo apt-get install -f [sudo] password for gnace: Reading package lists...

The gui installers pop-ups all say that my system has broken dependencies, and suggest using "sudo apt- get install -f". Unfortunately I'm not fluent enough with dpkg to try using that command without some guidance. -- You received this bug notification because you are a member of OpenJDK, which is subscribed to openjdk-8 in Ubuntu. https://bugs.launchpad.net/bugs/1806265 Title: package openjdk-8-jre-headless 8u181-b13-1ubuntu0.18.04.1 failed to install/upgrade: trying to overwrite shared '/etc/java-8-openjdk/security/java.security', which is different from other instances of package openjdk-8-jre-headless:amd64 Status in openjdk-8 package in Ubuntu: New Bug description: Package crash on automated install.
