DPKG-REPACK(1) dpkg suite DPKG-REPACK(1)


dpkg-repack - put an unpacked .deb file back together


dpkg-repack [option...] package-name...


dpkg-repack creates a .deb file out of a Debian package that has already been installed on your system.

If any changes have been made to the package while it was unpacked (e.g. conffiles files in /etc modified), the new package will inherit the changes. (There are exceptions to this, including changes to configuration files that are not conffiles, including those managed by ucf(1).)

This utility can make it easy to copy packages from one computer to another, or to recreate packages that are installed on your system, but no longer available elsewhere.

Note: dpkg-repack will place the created package in the current directory.


Take package from filesystem rooted on dir. This is useful if, for example, you have another computer NFS mounted on /mnt, then you can use --root=/mnt to reassemble packages from that computer.
Make the package be for a specific architecture. dpkg-repack might not be able to tell if an installed package is architecture all or is specific to the system's architecture, in case it lacks the Architecture field. If you know the package architecture, you can use this option to force dpkg-repack to use the right architecture.
Pass option as build argument to dpkg-deb. This option can be specified multiple times.
Generate a temporary directory suitable for building a package from, but do not actually create the package. This is useful if you want to move files around in the package before building it. The package can be built from this temporary directory by running "dpkg-deb --build dir ." as root (or by using fakeroot -u), where dir is the generated directory.
Specify a comma-separated list of things to tag in the package as having been repackaged. The current list of things to tag is:
Tag nothing. This can be specified first to be augmented by more specific things.
Append a timestamped "Repackaged by dpkg-repack" tagline to the package's control file Description field. This tag is enabled by default.
Append a "+repack" tag to the package version.
Tag everything.
The name of the package to attempt to repack. Multiple packages can be listed.


There is a tricky situation that can occur if you dpkg-repack a package that has modified conffiles. The modified conffiles are packed up. Now if you install the package, dpkg(1) does not realize that the conffiles in it are modified. So if you later upgrade to a new version of the package, dpkg(1) will believe that the old (repacked) package has older conffiles than the new version, and will silently replace the conffiles with those in the package you are upgrading to.

While dpkg-repack can be run under fakeroot(1) and will work most of the time, fakeroot -u must be used if any of the files to be repacked are owned by non-root users. Otherwise the package will have them owned by root. dpkg-repack will warn if you run it under fakeroot(1) without the -u flag.
