deb−postinst − package post−installation maintainer script
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 remove.
postinst
abort-deconfigure in-favour new-package
new-version
[ removing old-package old-version ]
If prerm fails during deconfigure in-favour of a package.
postinst abort-remove in-favour new-package new-version
If prerm fails during remove in-favour for replacement due to conflict.
