Doing

$ ldi upload logilab-backports inosync_0.2.3~9c78d8cf34-1_amd64.changes
ERROR: /home/logilab/repositories/logilab-backports/incoming/wheezy/inosync_0.2.3~9c78d8cf34-1_all.deb already eists, skipping; use '--force' to overwrite
ERROR: /home/logilab/repositories/logilab-backports/incoming/wheezy/inosync_0.2.3~9c78d8cf34-1_amd64.changes alrady exists, skipping; use '--force' to overwrite
