Package: locales Version: 2.28-10 To support MacOS terminal I have to define "UTF-8" using localedef (see #952516). Problem is, custom locales are wiped out by the postinst script. Sample: # locale -a C C.UTF-8 POSIX # localedef -i C -f UTF-8 UTF-8 # locale -a C C.UTF-8 POSIX UTF-8 UTF-8.utf8 # apt reinstall locales : : # locale -a C C.UTF-8 POSIX See UTF-8 is gone? Shouldn't happen. Same for locales 2.31-1. Harri
