MsgMerge addon error

[Erwane]

Hi,

I'm trying to enable msgmerge addon but there is an error in log :

weblate-1  | celery-celery stderr | AttributeError: type object 'PoMonoFormat' has no attribute 'update_bilingual'

My project use "monolingual" gettext POT file.

Weblate version : 5.11.3

Do you have any ideas for this ?
Thanks

There should be no use for mermerge on monolingual files, it's bug that the add-on can be installed there. Tracked as #14814

ok, thanks, so, how update translations from POT ?

My app use gettext keys, like app.menu.home. With a console command i extract all keys into a POT file.
I push those POT on repository and my components use this pot file for "new language" but how to update existing languages with new keys ?

Thanks a lot.

The new keys are added as they are translated. If you need all keys to be present, you can use https://docs.weblate.org/en/latest/admin/addons.html#prefill-translation-with-source
