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