Unattended upgrades are being installed on my servers



As an example of an unattended upgrade:



openssh-server                      1:6.6p1-2ubuntu2.11


On system1 I see that openssh-server 1:6.6p1-2ubuntu2.10 is still there, while openssh-sftp-server has been updated to 1:6.6p1-2ubuntu2.11



On system2 I see that both packages have been upgraded to 1:6.6p1-2ubuntu2.11



There is a dist difference between both servers:





  • system1:



    Linux 3.13.0-141-generic #190-Ubuntu SMP Fri Jan 19 12:52:38 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux



  • system2:



    Linux 3.13.0-29-generic #53-Ubuntu SMP Wed Jun 4 21:00:20 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux



So on the newer one (system2) the package upgrade has not been done. Why is this?

Check your unattended-upgrades logs to see when U-U last ran on each system, and what it's logic concluded in each case. openssh-server was updated on 06 Nov 2018, allow an extra day-or-two for timezones and mirrors to sync.
