canlock binary package in Ubuntu Jammy arm64

 Cancel locks are used by Usenet article posters to authenticate their
 authorship of an article. It may then by used by servers to prevent
 cancel and supersede abuse. The use of this feature remains the
 newsmaster's decision.
 .
 This package contains a simple utility wrapping the canlock library,
 which may be used for both the generation and the verification of
 cancel locks, along with a message header parser and a header field
 parser.
