.IX Header "DESCRIPTION"
A package can perform several post-installation actions via maintainer
scripts, by including an executable \fIpostinst\fR file in its control
archive (i.e. \fIDEBIAN/postinst\fR during package creation).
.PP
The script can be called in the following ways:
.IP "\fIpostinst\fR \fBconfigure\fR \fIold-version\fR" 4
.IX Item "postinst configure old-version"
After the package was installed.
.ie n .IP "\fIpostinst\fR \fBtriggered\fR ""\fItrigger-name...\fR""" 4
.el .IP "\fIpostinst\fR \fBtriggered\fR ``\fItrigger-name...\fR''" 4
.IX Item "postinst triggered ""trigger-name..."""
After the package was triggered.
The list of space-separated \fItrigger-name\fRs is passed as the second
argument.
.IP "\fIold-postinst\fR \fBabort-upgrade\fR \fInew-version\fR" 4
.IX Item "old-postinst abort-upgrade new-version"
If \fIprerm\fR fails during upgrade or fails on failed upgrade.
.IP "\fIold-postinst\fR \fBabort-remove\fR" 4
.IX Item "old-postinst abort-remove"
If \fIprerm\fR fails during removal.
.IP "\fIpostinst\fR \fBabort-deconfigure in-favour\fR \fInew-package new-version\fR" 4

If \fIprerm\fR fails during deconfiguration of a package.
.IP "\fIpostinst\fR \fBabort-remove in-favour\fR \fInew-package new-version\fR" 4
.IX Item "postinst abort-remove in-favour new-package new-version"
