mkisofs stopps without err msg

[jens]

Hi,

after removing and installing some deb packages, i can't mkisofs any more.
It stopps without any err msg after compressing Block 0. Any ideas what's going wrong here?
Tx, Jens

This is the last output:

it seems to be necessary (and useful to minimize required disk space) to delete all package files under /var/cache/apt/archives
