freebayes binary package in Ubuntu Focal armhf

 FreeBayes is a Bayesian genetic variant detector designed to find
 small polymorphisms, specifically SNPs (single-nucleotide
 polymorphisms), indels (insertions and deletions), MNPs
 (multi-nucleotide polymorphisms), and complex events (composite
 insertion and substitution events) smaller than the length of a
 short-read sequencing alignment.
