Problem solved itself. I realised I had installed VirtualBox, but system
crashed during installation of this package. After three restarts of system I
ran 'apt-get update' and I got no error message. The only one thing I had to do
was reinstall VirtualBox.
I hope this will help others who have t
kages like MPlayer, Firefox, GIMP, Krusader, codecs for video files,
samba, apache+mysql+php, proftpd, but all these packages I use on my desktop
over 5 month and I have never had this problem...
Thanks for any idea, otherwise I will have to reinstall my system...
