i see two errors:
- your role lacks the Delete permission on the 'RPMS' smart group in the catalog
- your role lacks the Delete permission on a particular depot software object in the catalog (libgpg-error-devel-1.4-2.i386.rpm)
so you need to:
- do the delete as a role w/ the delete permission on these objects
- login as a role w/ permission to modify acls on these objects and grant BLAdmins the delete permission.
Also make sure you have access to delete any upward job the patches could be linked to, or you'll have the same issue there.
