+- I ran the DSpace cleanup function on CGSpace and it found some errors:
+
+```
+$ dspace cleanup -v
+...
+Error: ERROR: update or delete on table "bitstream" violates foreign key constraint "bundle_primary_bitstream_id_fkey" on table "bundle"
+  Detail: Key (bitstream_id)=(171221) is still referenced from table "bundle".
+```
+
+- The solution, as always, is (repeat as many times as needed):
+
+```
+# su - postgres
+$ psql dspace -c 'update bundle set primary_bitstream_id=NULL where primary_bitstream_id in (171221);'
+UPDATE 1
+```
