deb-postinst

DEBIAN/postinst

A package can perform several post-installation actions via maintainer scripts, by including an executable postinst file in its control archive (i.e. DEBIAN/postinst during package creation).

The script can be called in the following ways:

postinst configure old-version

After the package was installed.

postinst triggered "trigger-name..."

After the package was triggered. The list of space-separated trigger-names is passed as the second argument.

old-postinst abort-upgrade new-version

If prerm fails during upgrade or fails on failed upgrade.

old-postinst abort-remove

If prerm fails during removal.

postinst abort-deconfigure in-favour new-package new-version

       [ removing old-package old-version ]

If prerm fails during deconfiguration of a package.

postinst abort-remove in-favour new-package new-version

If prerm fails during replacement due to conflict.
