libuuid1 2.36-3ubuntu1 (amd64 binary) in ubuntu groovy

 The libuuid library generates and parses 128-bit Universally Unique
 IDs (UUIDs). A UUID is an identifier that is unique within the space
 of all such identifiers across both space and time. It can be used for
 multiple purposes, from tagging objects with an extremely short lifetime
 to reliably identifying very persistent objects across a network.
