Package: libpwquality1 $ apt show libpwquality1|grep Depends Depends: libc6 (>= 2.14), libcrack2 (>= 2.8.12), libpwquality-common
libpwquality-common depends on nothing. the library meanwhile has pwquality_strerror(...) which is meant to provide localized error strings for display. except it can't because the translations are in libpwquality-tools which is not pulled in. translations should be in common package so the library can actually construct useful error strings. this bug effectively renders translations unavailable by default
