deb-prerm - package pre-removal maintainer script
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<DEBIAN/prerm>
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
A package can perform several pre-removal actions via maintainer
|
|
scripts, by including an executable I<prerm> file in its control
|
|
archive (i.e. I<DEBIAN/prerm> during package creation).
|
|
|
|
The script can be called in the following ways:
|
|
|
|
=over
|
|
|
|
=item I<prerm> B<remove>
|
|
|
|
Before the package is removed.
|
|
|
|
=item I<old-prerm> B<upgrade> I<new-version>
|
|
|
|
Before an upgrade.
|
|
|
|
=item I<new-prerm> B<failed-upgrade> I<old-version> I<new-version>
|
|
|
|
If the above B<upgrade> fails.
|
|
|
|
The I<new-version> is passed only since dpkg 1.18.5.
|
|
|
|
=item I<prerm> B<deconfigure> B<in-favour> I<new-package> I<new-version>
|
|
|
|
=item S< >[ B<removing> I<old-package> I<old-version> ]
|
|
|
|
Before package is deconfigured while dependency is replaced due to conflict.
|
|
|
|
=item I<prerm> B<remove> B<in-favour> I<new-package> I<new-version>
|
|
|
|
Before the package is replaced due to conflict.
