Tag: library-in-root-and-usr Severity: error Check: usrmerge Explanation: The package ships two files with the same name installed both in /lib*/ and /usr/lib*/ (or their subdirectories). This is not useful and is incompatible with the merged /usr directories scheme. . Shared library files, both static and dynamic, must be installed in the correct directories as documented in Policy 8.1. See-Also: https://wiki.debian.org/UsrMerge, debian-policy 8.1
