Source: ca-certificates-local Section: misc Priority: extra Maintainer: System Administrator Build-Depends: debhelper (>= 8.0.0) Standards-Version: 3.9.4 Package: ca-certificates-local Architecture: all Depends: ca-certificates (>= 20130119), ${misc:Depends} Description: Local CA certificates This package includes local CA certificates to be installed in /usr/local/share/ca-certificates. The CA certificates installed by this package will be implicitly trusted. . This is an example stub source package that includes a dummy CA certificate in the local/ directory. Remove the dummy certificate, copy your trusted local root CA (in PEM format with the filename ending in ".crt") to the local/ directory, edit files in the debian/ directory as desired, and build your custom package.
