[SOLVED] Unmet dependencies?

[rapattack]

Hi I am getting this when trying to install an app:

# apt-get install kdenlive
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
kdenlive: Depends: libmlt++0.2.3 (>= 0.2.2) but it is not going to be installed
Depends: libmlt0.2.3 (>= 0.2.2) but it is not going to be installed
E: Broken packages

Does anyone know what this means?

Execute this

su
apt-get clean all
apt-get update
apt-get install kdenlive

Post error message here, if any.

su root
Password:
carla:/home/carla# apt-get clean-all
E: Invalid operation clean-all

No, not clean-all...

It should be clean all without a dash in it.

Ooops....late night!

Is this right?

Ooops I did apt-get update and then apt-get install kdenlive and got the same unmet dependencies error/problem.

Ah I just noticed the apt-get autoremove....does this mean that I have to type those things like libglib1.2dbl ? I dunno in what order or how?

[devils casper]

Just execute apt-get autoremove command.
