dpkg-repack

[bhobjj]

dpkg-repack can be used to recreate a debian package from an installed program:

Here (http://zgp.org/pipermail/linux-elitists/2007-March/011847.html) is a fine hack to use dpkg-repack for undoing an upgrade.

A handy little tool. My usual upgrade-procedure is:

mkdir /root/lib/upgrades/`date +%Y-%m-%d` ; cd /root/lib/upgrades/`date
+%Y-%m-%d`

dpkg-repack `apt-get -s upgrade | grep "^Inst" | awk '{ print $2 }'`

or

dpkg-repack `apt-get -s dist-upgrade | grep "^Inst" | awk '{ print$2 }'`

respectively.

So if anything goes wrong i only have to

cd /root/lib/upgrades/`date +%Y-%m-%d`

and

dpkg -i *



Cheers

At some time I must have installed dpkg-repack, but I don't recall when, or why.

Didn't know anything about it until your posting. Thanks!

Howdy,

dpkg-repack has been a gem on many an occasion.

Yes, it's a very usefull tool, and very light on install space. It basically just reverses out of the data-base --- i think it just uses the relevant files in /var/lib/dpkg/info for and recreates a deb package for the package name supplied as a cli option. Along with any modifications.

Excellant for transfering packages across discs.

The 'equiv' packahe is also worth looking at too if not already. Ch 4 (i think) of the Apt-HowTo covers it quite well.

There is quite a lot of good stuff salted away in the docs if a person should actually go looking and it also reflects the design principle of deb as being orientated towards customisation, as well as overall stability.
