[Bug 1821103] Re: [SRU] Skip sending email when no package had to be installed, upgraded or removed

[Balint Reczey]

** Description changed:

- .
+ [Impact]
+ 
+  * Users get unattended-upgrade's email report every day or every time u-u ran, even when no package needed to be upraded, installed or removed. This can annoy administrators managing many servers.
+  * The fix is sending the report email only when there were actions taken by u-u.
+ 
+ [Test Case]
+ 
+  * The extended autopkgtest script checks if no email is sent when u-u
+ did not upgrade packages.
+ 
+ [Regression Potential]
+ 
+  * Unattended-upgrades may skip sending emails which would contain
+ useful information, but given the size and the simplicity of the scripts
+ this seems unlikely.
