I have the same problem on more physical PC's and VMware virtual
machines including Ubuntu 17.10. I suppose it is not Unity problem but
update manager in GUI. The issue persists at least two years from
version 16! Actually I have only one server running with old Ubuntu
14.04 LTS which is OK. All others have the same issue. Am I alone who is
disgusted the problem persists such long time?
