Dependencies? trouble when installing new software

[n_nuos]

Hello, guys!
for various reasons I ended up with no OS and I did a hdd install on a Knoppix 4 cd that I had.
Now I am trying to install additional software and I am getting some weird messages from kpackage:

<pt-get install -m --ignore-hold --yes 'valknut' ;echo RESULT=$?
Reading Package Lists... 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:
valknut: Depends: libqt3-mt (>= 3:3.3.6) but it is not going to be installed
E: Broken packages
RESULT=100

I got the same results when trying to install synaptic or vlc
please give me a hand

As you are using Knoppix4 you will have older libraries such as, specifically, libqt3c102-mt which is in conflict with the libqt3-mt that your intended new software requires.

Depending on what you are trying to install and what you want to keep, it is possible to hack-in the substitution but if I remember you might have to change some other packages as well.
Also you are likely to need more fine-grained control of the packaging process, by using apt and/or dpkg. Also, wajig is a handy front-end command line tool if you can install that.

If on the other hand you want a quick result, I suggest that you start from a more recent Knoppix viz. 5.x

Another possibility might be to see if the new software that you require is available in Debian Backports.

Good luck.
