I am trying to remove my repository in Settings → General → Advanced (Housekeeping, export, path, transfer, remove, archive. )
But here is no REMOVE button there!!! Could you tell me how to remove a repository ? Thank you!
What are your permissions on that project? According to this: Project settings | GitLab
only project maintainers (owners) and administrators can delete. So if you are not the owner of the project, or you don’t have administrator rights then you won’t be able to delete it.
On this page: Permissions and roles | GitLab
you will see delete project requiring owner permissions.
