As you can see, there are still a lot of things to translate.
I’ve tried altering/adding translations to – seafile-server-latest/seahub/locale/pt_BR/LC_MESSAGES/django.po – but it didn’t work.
I’ve also tried setting up LC_ALL and other locales to brazilian portuguese with and without UTF-8, nothing.
You can edit django.po and then use msgfmt command from gettext package to compile django.po to get django.mo.
Or better yet, you can join the team to help translate seafile in https://www.transifex.com/haiwen/seahub/language/pt_BR/
