broken packages qt3-dev, libdrm-dev

Hi I tried to install qt3-dev-tools in order to try to run make xconfig for compiling a new kernel. The installation failed. apt-get install -f was recommended, but also failed with the following message Unpacking libdrm-dev (from .../libdrm-dev_2.4.18-1ubuntu3_i386.deb) ... dpkg: error processing /var/cache/apt/archives/libdrm-dev_2.4.18-1ubuntu3_i386.deb (--unpack): trying to overwrite '/usr/include/drm/nouveau_drm.h', which is also in package linux-libc-dev 0:3.7.0-2 dpkg-deb: subprocess paste killed by signal (Broken pipe) Errors were encountered while processing: /var/cache/apt/archives/libdrm-dev_2.4.18-1ubuntu3_i386.deb E: Sub-process /usr/bin/dpkg returned an error code (1) Now all my packages are broken and I can't install anything. This never happened. Any ideas? Uwe Brauer
