Package: dpkg Version: 1.19.7 Trying to replace a directory with a symlink on the upgrade of a private package I stumbled over this:

Please note the empty directory instead of the symlink after the installation of adoptopenjdk11_11.0.8+10-1_amd64.deb. The predecessor of my adoptopenjdk11 package provided the whole JDK in /usr/lib/jvm/java-11-AdoptOpenJDK. The JDK is now supposed to be provided by the Debian package from https://adoptopenjdk.jfrog.io/adoptopenjdk/deb/pool/main/a/adoptopenjdk-11-hotspot/ For backward compatibility I tried to introduce a symlink in my new adoptopenjdk11 package, as shown above. Reinstalling the new package doesn't help, either: root@dpcl082:/usr/lib/jvm# dpkg -i /var/cache/apt/archives/adoptopenjdk11_11.0.8+10-1_amd64.deb (Reading database ... 366514 files and directories currently installed.)
