dpkg: warning: while removing directory /usr/local not empty so not removed

问题

I built and installed a debian package from the following folder structure:

• myprog
  • DEBIAN
    • control
  • usr
    • local
      • bin
        • myprog.sh

... using the following commands:

dpkg -b myprog/ myprog.deb && dpkg -i myprog.deb

When i now remove the package by typing:

dpkg -r myprog

.. I got the following warning:

dpkg: warning: while removing myprog, directory '/usr/local' not empty so not removed.

As I think this is an every day scenario, how can I avoid the warning?

# Edit

I tried to install the file to /bin instead of /usr/local/bin and got no warning when removing it. Seems so, that the /usr/local/.. folder will not treated as a system folder (?) by dpkg.

回答1:

That's right -- packages should never touch /usr/local directory, it's reserved for system administrators by Filesystem Hierarchy Standard and is their zone of responsibility.

回答2:

To avoid the warning, according to this post, is to create a "core-custom"/dummy package, which will install in /opt, and be required by your main package.

So, when you'll uninstall your main package, at least your dummy package will be left in /opt and dpkg will not issue the warning.

You can also use that dummy package as a meta-package to install all the regular packages you like.
