golang-gopkg-natefinch-lumberjack.v2-dev binary package in Ubuntu Focal amd64

 Lumberjack is intended to be one part of a logging infrastructure.
 It is not an all-in-one solution, but instead is a pluggable component
 at the bottom of the logging stack that simply controls the files
 to which logs are written.
 .
 Lumberjack plays well with any logging package that can write to
 an io.Writer, including the standard library's log package.
 .
 Lumberjack assumes that only one process is writing to the output
 files. Using the same lumberjack configuration from multiple processes
 on the same machine will result in improper behavior.
 .
 This is version v2 of the lumberjack package.
