valgrind-if-available 3.18.1-1-1 (armhf binary) in ubuntu lunar

 This metapackage installs Valgrind on architectures where it is available.
 As the list of archs where Valgrind works changes quite often, explicitly
 listing it as a [Build-]Depend is cumbersome and prone to being outdated.
 Instead, you may use this metapackage.
