Package: libudev Version: 232-25+deb9u2 Severity: important Dear Maintainer,
When I attempt to install libudev-dev on stretch I get the error below. This prevents me from installing other packages such as libpci-dev and libsnmp-dev. sudo apt-get install libudev-dev Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
