lingot 1.1.1-1 (riscv64 binary) in ubuntu groovy

 Lingot is a musical instrument tuner. It's accurate, easy to use, and
 highly configurable. Originally conceived to tune electric guitars,
 it can now be used to tune any instrument.

 It looks like an analogic tuner, with a gauge indicating the relative
 shift to a certain note indicating that note and its frequency.
