"Invalide" => "Invalid"

Est "invalide" la traudction en français?

It would be good to document the subparser parameter here.

optionnel:
Devrions nous vérifier que la date n'est pas déjà expiré?

data or date? The text says data, but the variable says date.

LGTM

date indeed

hm, good idea yes

Vous pourriez utiliser datetime.strptime(args.date, '%Y-%m-%d').date() au lieu de arrow.

Oui monsieur :)

Small changes but otherwise LGTM.

Fair, though I would still have to get it a timezone as the field in the DB is TZ aware (UTC tz though) and arrow is already a dependency of pagure, so not a new one :)

Adjusted and rebased :)

tests/test_pagure_admin.py is passing, running the entire suite before I merge :)

You should move this out of the try block so the except doesn't catch the PagureException.

Good catch, done :)

Tests passed \ó/
