I rencently upgraded my gitlab-ce to 13.12 because i saw this feature, and realised I don't have Packages & Registries in my settings. Is there anything i miss here ?
Be aware that this is a GROUP LEVEL
setting and not a project level setting.
To change this select the Group containing the project, where you want this feature. Within the settings for the group, you will find a section called Packages and Registries
.
