Re: list of depedencies

Apt (and the front-ends) only show the first level dependencies:

Example:

apt-cache show kcometen4

or

apt-cache depends kcometen4

will tell:

Depends: kdebase-runtime (>= 4:4.1.96), kdebase-workspace-libs4+5, kdelibs5 (>= 4:4.1.96), libc6 (>= 2.4), libgcc1 (>= 1:4.1.1), libgl1-mesa-glx | libgl1, libglu1-mesa | libglu1, libqt4-opengl (>= 4.4.3), libqtcore4 (>= 4.4.3), libqtgui4 (>= 4.4.3), libstdc++6 (>= 4.1.1)

apt-cache depends output will be:

kcometen4
Depends: kdebase-runtime
Depends: kdebase-workspace-libs4+5
Depends: kdelibs5
Depends: libc6
Depends: libgcc1
|Depends: libgl1-mesa-glx
Depends: <libgl1>
libgl1-mesa-glx
libgl1-mesa-swx11
|Depends: libglu1-mesa
Depends: <libglu1>
libglu1-mesa
Depends: libqt4-opengl
Depends: libqtcore4
Depends: libqtgui4
Depends: libstdc++6

But there is an application that will list the second and third (4.th...) level dependencies:

Package: apt-rdepends

Description: Recursively lists package dependencies
This utility can recursively list package dependencies, either forwards
or in reverse. It also lists forward build-dependencies. The output
format closely resembles that of `apt-cache depends`. As well, it can
generate .dot graphs, much like apt-cache in dotty mode.

=>

apt-rdepends kcometen4

and the output:

kcometen4
Depends: kdebase-runtime (>= 4:4.1.96)
Depends: kdebase-workspace-libs4+5
Depends: kdelibs5 (>= 4:4.1.96)
Depends: libc6 (>= 2.4)
Depends: libgcc1 (>= 1:4.1.1)
Depends: libgl1
Depends: libgl1-mesa-glx
Depends: libglu1
Depends: libglu1-mesa
Depends: libqt4-opengl (>= 4.4.3)
Depends: libqtcore4 (>= 4.4.3)
Depends: libqtgui4 (>= 4.4.3)
Depends: libstdc++6 (>= 4.1.1)
kdebase-runtime
Depends: kde-icons-oxygen (>= 4:4.2.0-0ubuntu1)
Depends: kdebase-runtime-bin-kde4 (= 4:4.2.0-0ubuntu1)
Depends: kdebase-runtime-data (>= 4:4.2.0-0ubuntu1)
Depends: kdelibs5 (>= 4:4.1.96)
Depends: libasound2 (>> 1.0.18)
...clicp..
kdebase-runtime-bin-kde4
Depends: kdebase-runtime (>= 4:4.1.96)
Depends: kdelibs5 (>= 4:4.1.96)
Depends: libc6 (>= 2.3.4)
Depends: libgcc1 (>= 1:4.1.1)
Depends: libqt4-dbus (>= 4.4.3)
Depends: libqt4-network (>= 4.4.3)

Depends: libqt4-xml (>= 4.4.3)
Depends: libqtcore4 (>= 4.4.3)
Depends: libqtgui4 (>= 4.4.3)
Depends: libstdc++6 (>= 4.1.1)
Depends: libx11-6
kdelibs5
Depends: dbus-x11
Depends: kdelibs-bin (>= 4:4.2.0-0ubuntu2)
Depends: kdelibs5-data (>= 4:4.2.0-0ubuntu2)

Great stuff, Rog -- Thanks!

Re: list of depedencies

thanks...
what about the list of packages that havnt been installed or downloaded

[kasunbg]

Re: list of depedencies

I also have the same problem. Why does it need to download dependencies separately Everytime I downloads a file from from one computer and when I try to install it in another computer, It always says the dependencies are not satisfied . It's kind of headache to me. I have bunch of setups with me but nothing can be installed. Please can someone give me a solution for this?
Is there a place or site that I can download the software with all the dependencies

Thanks in advance.

There could be (https://help.ubuntu.com/community/OperaBrowser):

Static version:

Opera has the Qt library built in. It is a larger download, and it does not use anti aliased fonts on menus or the file chooser, and uses aliasing in the browser window and most other interface elements.

Shared version:

Opera uses the Qt installation on your system. It integrates with the system, using whatever anti aliasing setting you have for other Qt applications.

Without net connection it is a pain to solve the dependencies. Here (>Dependency network) is a page whitch will:

graphically displays the dependencies, called dependency maps. Search for your favorite package and see how dependent a software is on other packages.

An example graph > Adept graph

Note !
You could make those graphs yourself (kind of) > Viewing dependencies graphically on apt based systems.

Re: list of depedencies

Hmm - maybe something like this ( not recommended - maybe someone else knows a better way ):


Packages that will be needed

apt-rdepends --show=DEPEND package_name_here | sort > Depends.txt

/1/, /2/

Already installed

Earlier > FAQ: How to get list of installed packages

=> Modifying a bit =>

dpkg --get-selections | grep -v deinstall | awk '{ print $1 '} | sort > Installed.txt

or

dpkg --get-selections | awk '$2 !~/deinstall/{ print $1 '} | sort > Installed.txt

/3/


Looking differences

This should tell the packages that will be need to install:

comm -23 Depends.txt Installed.txt

/4/


BUT (and it is a very big fat BUT)

This will list virtual packages /5/ as needed to install, even when it is allready installed.
This will list packages that have conditional packages (package foo or package fii) =>

Depends: foo | fii

=> will list both packages as needed to install...




/1/ man apt-rdepends

NAME
apt-rdepends - performs recursive dependency listings similar to apt-cache

SYNOPSIS
apt-rdepends [options] [pkgs ...]

/2/ man sort

NAME
sort - sort lines of text files

SYNOPSIS
sort [OPTION]... [FILE]...

/3/ > The GNU Awk User's Guide

/4/ man comm

NAME
comm - compare two sorted files line by line

SYNOPSIS
comm [OPTION]... FILE1 FILE2

DESCRIPTION
Compare sorted files FILE1 and FILE2 line by line.

With no options, produce three-column output. Column one contains lines unique to FILE1, column two contains lines unique to
FILE2, and column three contains lines common to both files.

-1 suppress lines unique to FILE1

-2 suppress lines unique to FILE2

-3 suppress lines that appear in both files

/5/ > Debian Policy Manual Chapter 3 - Binary packages

3.6 Virtual packages

Sometimes, there are several packages which offer more-or-less the same functionality. In this case, it's useful to define a virtual package whose name describes that common functionality. (The virtual packages only exist logically, not physically; that's why they are called virtual.) The packages with this particular function will then provide the virtual package.
