You need to remove kio-stash from kdereview in repo-metadata, this will mess up the translations. You have i18n() used but no Messages.sh to extract the messages. You need to include a full copy of GPL 2 in a file called COPYING in the top level of the repo. You should include an AppStream file and add a screenshot to product-screenshots https://community.kde.org/Guidelines_and_HOWTOs/AppStream https://phabricator.kde.org/source/websites-product-screenshots/ Jonathan
