[Bug 1555237] Re: Upgrade from 14.04.4→ 16.04 dies midway taking out the session.

[Will Cooke]

>From Dave's Apt Term Log he got as far as being asked a question in the
terminal:

There are services installed on your system which need to be restarted
when certain libraries, such as libpam, libc, and libssl, are upgraded.
Since these restarts may cause interruptions of service for the system,
you will normally be prompted on each upgrade for the list of services
you wish to restart.  You can choose this option to avoid being
prompted; instead, all necessary restarts will be done for you
automatically so you can avoid being asked questions on each
library upgrade.
                                                                 
Restart services during package upgrades without asking?                


I got as far as this, then expanded the terminal view in the upgrader, answered "Y" and the install carried on.  

And then it crashed later on....

(From my term log):

insserv: Default-Start undefined, assuming empty start runlevel(s) for script `cron'
insserv: Default-Stop  undefined, assuming empty stop  runlevel(s) for script `cron'
insserv: warning: script 'cron' missing LSB tags and overrides
insserv: Default-Start undefined, assuming empty start runlevel(s) for script `cron'
insserv: Default-Stop  undefined, assuming empty stop  runlevel(s) for script `cron'
Setting up bash-completion (1:2.1-4.2ubuntu1) ...
Setting up liblocale-gettext-perl (1.07-1build1) ...


However - I noticed that the Upgrader window became grey and
unresponsive slightly before that.  Maybe as much as 5 mins earlier.

I have attached my apt term log.


So question 1:  Should that prompt actually open a window to prompt the user?
Question 2:  why did mine crash later on?
