The libosmo-sccp-dev package is no longer provided by libosmo-sccp. Without this patch, an older version of the library from debian packages gets installed, resulting in a conflict for sccp_types.h which is now in libosmo-sccp-dev.
Fix for: #6 8.585 dpkg: error processing archive /tmp/apt-dpkg-install-llkDLH/25-libosmo-sigtran-dev_1.9.0.3.fc4c.202409092026_amd64.deb (--unpack): #6 8.585 trying to overwrite '/usr/include/osmocom/sccp/sccp_types.h', which is also in package libosmo-sccp-dev:amd64 1.6.0+dfsg1-3
