Hello, dpkg tracks modifications that you make to configuration files. It's complicated.
But the end result is that you can get these files back by simply purging the packages and then installing them again: apt-get purge openjdk-8-jre-headless openjdk-8-jdk apt-get install openjdk-8-jre-headless openjdk-8-jdk Thanks -- 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/1552500 Title: No properties installed in /etc/java-8-openjdk/ Status in openjdk-8 package in Ubuntu: Incomplete Bug description: Folder /etc/java-8-openjdk/ is not created and all properties and cfg files are missing after installing from pool/universe/o/openjdk-8/openjdk-8-jre-headless_8u66-b17-1_amd64.deb with: apt-get install openjdk-8-jre-headless openjdk-8-jdk These files should be installed, but are all missing: root@ThinkPad-T500:/# dpkg -S /etc/java-8-openjdk/*.* openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/images/cursors/cursors.properties openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/accessibility.properties openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/security/java.security openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/swing.properties openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/management/snmp.acl openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/sound.properties openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/jvm-amd64.cfg openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/logging.properties openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/calendars.properties openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/flavormap.properties openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/management/jmxremote.password openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/content-types.properties openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/psfont.properties.ja openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/psfontj2d.properties openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/security/java.policy openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/security/blacklisted.certs openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/net.properties openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/management/jmxremote.access openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/management/management.properties openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/security/nss.cfg In consequence, e.g. NetBeans IDE 8.1 fails with: root@ThinkPad-T500:/# /usr/local/netbeans-8.1/bin/netbeans Unrecognized option: -client Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. NetBeans IDE 8.1 still freezes while starting when pinning to 8u45 from vivid and copying jvm-amd64.cfg from java-7 because only 3 files where installed: openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/accessibility.properties openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/security/java.security openjdk-8-jre-headless:amd64: /etc/java-8-openjdk/security/java.policy NetBeans IDE 8.1 runs fine with java-7 after applying the workaround from https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=808860 How did I ran into this situation? NetBeans IDE 8.1 ran fine for long time in my Ubuntu 15.04 with java-8. Last week I upgraded to 15.10. Since then it freezed after 2 minutes. Because I first didn't know about above mentioned bug, I tried several things including new installations of NetBeans and JDK. While doing this at some moment I deleted the /etc/java-8-openjdk/ folder, which was filled like the above list from former installations. I thought, I could delete it in assuming it would become created again when installing openjdk-8-jdk package. But this was not the case. Don't know, which build of jdk-8 I should install to get the files back, 8u45 only did recover 3 files of them. Because with 8u66-b17-1 no security properties where installed, I file this bug as a security vulnerability.
