notmuch-addrlookup binary package in Ubuntu Focal riscv64

 This package uses the Notmuch database to output the names and e-mail
 addresses of the people you have exchanged e-mails with, most used ones
 first. This works neatly as address completer for the Notmuch Emacs
 interface.
 .
 The program works by invoking from a shell. The only argument it takes is
 a string, which is searched for in the e-mail addresses contained in the
 headers of the messages indexed by Notmuch.
