I'm not able to test 1.9 as this is a production server.

The <host> from #919972 shows the same problem after upgrading to 1.9

Subject:
[package on hold] unattended-upgrades result for <host>: SUCCESS

Unattended upgrade result: All upgrades installed

Packages with upgradable origin but kept back:
  libcurl4


As I said in #919972 1.9 shows correct message "Packages with upgradable
origin but kept back", but subject is wrong: "[package on hold]"

Hi Sergio,

Yes, the definition of success and the subject line could be revisited
as it was discussed here, too:
