You didn't relay what package manager you are using my old friend.


That sounds like something aptitude would do. I've had 2 systems totally 
destroyed by it now, the last one because it assumed an automatic yes 
that I didn't give it.  So I don't trust anything but synaptic-pkexec to 
do the right thing anymore.  The pkexec means you run it as yourself, 
and it will ask you for your passwd to get its root privs, after it 
checks to see if you are in the sudoers file.

Because:

1) some of the things on that list declare libjack-jackd2-0 as a 
dependency (probably because they are libraries or programs which are 
linked against the libraries contained in libjack-jackd2-0), so will be 
removed due to having an unfulfilled dependency.

2) some of the things on that list declare things in (1) as 
dependencies, so will be removed due to having unfulfilled dependencies.

3) some of the things on that list may be automatically-installed 
prerequisites for things in (1) and (2) which no longer have any reason 
to be installed if everything in (1) and (2) is being removed, so will 
be removed due to being automatically-installed packages which no longer 
have a reason to be installed.

As a general rule, removing packages whose name begins with 'lib' and 
doesn't end in '-dev' or -doc' should be *expected* to produce this kind 
of result.

To recursively list all packages that are installed on a system and
are dependencies of a package, you can do

apt-rdepends --state-show=Installed --state-follow=Installed PKGNAME

Run the above command with PKGNAME as libjack-jackd2-0 and it should
give you an idea of why the package manager is trying to remove so
many packages.

It lists just a couple of base packages. So, why would it want to remove 
half of mmy installed desktop? It's the same with firefox. What gives?? Ric

kamaraju appears to have mistyped the command, omitting the vitally 
important (for this exercise) '-r' flag. As written, it will show you 
what PKGNAME depends on, directly or indirectly. The command is properly:

apt-rdepends -r --state-show=Installed --state-follow=Installed PKGNAME

(note the '-r' flag)

This will show you what *depends on* PKGNAME (either by depending on it 
directly, or by depending on something that does). Now, this still won't 
get you a full answer, because it won't show you all the Automatically 
Installed packages that will be removed, but it will give you a starting 
point for understanding what's going on.

Thanks for correcting me Martin. Yes, you are right. We need the -r
flag for this use case.

So just paste the output here.  Or at least say which packages.

My theory goes something like this. You have a desktop environment
package installed - something like gnome, or in your case perhaps
xubuntu-desktop (suggesting you're asking about Ubuntu on a Debian list,
but never mind). That depends on a lot of applications which have been
deemed useful for such a desktop.

Some of them (eg timidity) depend on this jack package, so if you remove
jack, timidity has to go, and therefore the desktop package has to go.

But because all those applications were only installed because the
desktop depended on them (ie you didn't install them manually), they're
marked as automatic. So when you remove the desktop, aptitude at least
assumes that you probably no longer want all those other packages
either, and removes them.

The solution, then, might be to 'aptitude unmark auto' all the packages
that are required by xubuntu-desktop which you still want, so that you
can remove the xubuntu-desktop package without having any other effect.
Of course, if any of the packages you want directly depend on
libjack-blah, you have a problem.

xubuntu-desktop might not be the actual (or only) culprit, of course.

And I'm not sure how non-aptitude package managers behave in this regard.

Richard
