Sometimes apt causes that, don't know why but when it does
# apt-get clean
So before you go chasing those log files that may have grown out of control try this first it might save you a few headaches.
from a root shell
gpg --keyserver wwwkeys.eu.pgp.net --recv-keys 1F41B907
gpg --armor --export 1F41B907 | apt-key add -
should take care of this error message and enable apt to authenticate the debian-marillat repositories.
KDE returns "Couldn't find MIME type application/octet-stream" at startup and/or Konqueror returns the same error message when launching whatever application.
Start the Control Center and open KDE Components/File Associations, you will see something like this
Expand "application", you will probably see that there's no entry for "octet-stream".
Click on "Add...", for "Group" select "application" and for "Type Name" fill in "octet-stream". This should fix it.
If you're lucky and use a debian-based distro like Sidux just apt-get install
w32codecs and you're good to go, if not this is how I used to do it a few years ago when I was still using the early Fedora releases.
First download the codec pack.
$ cd to dir where you saved the codec pack
$ tar jxvf w32codec.tar.bz2
$ cd to newly created dir with the codecs
$ su -m
$ password for root
# mkdir /usr/lib/win32
You're still in the dir with the codecs, right?
# cp *.* /usr/lib/win32
$ nmap -sT -O localhost
If you see something suspicious you can check it with
$ netstat -anp | grep xxx
where xxx is the number of the port you want info about.
