dependency tree on installed packages
 

Hello!

My Wheezy was installed on a very early stage any I would like to
compare packages against a fresh installation to see what is different
or changed. Probably nothing but would like to verify. Therefore I
would like to make a dependency tree (graph) on installed packages
under Wheezy for both (my older and a fresh) installation. On the two
dependency trees I am able to find differences between them because
packages by packages compare is not enough I think.

I have made some google and found that debtree and apt-cache might do
that. But do not. Or not exactly what I would like. debtree needs a
package name for graph but I need all my installed packages (no --all
or asterisk parameter) not just some and apt-cache makes tree from all
packages Debian has even I specify the parameter --installed. I am
stuck.

Any other idea for what I would like to do? Script or application or
just hint. Anything.

Bye,
a

apt-cache dump | grep Package:
apt-cache dump | grep Version:

Those will get 2 separate lists of installed software names & versions.

Maybe that will get what you want in a roundabout way. :-)

Thank you. Unfortunately it gives all Debian packages not just installed.

# apt-cache dump | grep Package: | wc -l
47121
# apt-cache --installed dump | grep Package: | wc -l
47121
# dpkg --list | wc -l
2481

It looks like "apt-cache --installed depends ." should do what you want.
If it's doing what you want, but for all packages, then that seems like
a bug to me (the --installed parameter says "Limit the output of depends
and rdepends to packages which are currently installed"). Note that
"--installed" only works with 'depends' and 'rdepends'.

I may have misunderstood what you are asking but maybe this:

aptitude -F%p search '~i'

Why don’t you use the output of dpkg -l? Also check man 1 dpkg-query.

This depends output looks very close to what I would like but
--installed does not works with depends for me even man page says so.

# dpkg --list | grep 0ad
# apt-cache --installed depends . | grep 0ad
0ad
0ad-data
0ad-dbg
# apt-cache --installed depends . | egrep -v '^ ' | wc -l
47121

Thanks but not really what I want. Its output is close to dpkg --list
and nothing about dependency which I would like.

Thank you. dpkg -l writes out all installed packages but not the
relations between them. I did similar comparison between systems but
seeing the differences in a tree makes this process easier because I
can cut leafs if I know there is related or not to my later
installation. If I compare packages line-by-line without any relation
I do not know that any extra or missing packages is related to other
packages or might "standalone" packages.

I think the continuous upgrade process from the early stage of Wheezy
left some unneeded packages. This is normal as I started early just
want to clean out my system. Maybe I am wrong on base idea but would
like to check and look for some utility to make it easier. I there is
no such utility I will compare line-by-line as last resort.

Bye,

I was implying to feed this output into higher level tools to
generate dependency graphs for you.

If you simply want to clean out your system, have a look at deborphan.
