Comment 2 for bug 1816334

Thank you for taking the time to report this bug and helping to make Ubuntu better.

From DpkgTerminalLog.gz looks like the upgrade process got interrupted while waiting for input from your side (e.g. ssh disconnected during the upgrade):

Configuration file '/etc/apache2/apache2.conf'
 ==> Modified (by you or by a script) since installation.
 ==> Package distributor has shipped an updated version.
   What would you like to do about it ? Your options are:
    Y or I : install the package maintainer's version
    N or O : keep your currently-installed version
      D : show the differences between the versions
      Z : start a shell to examine the situation
 The default action is to keep your current version.
*** apache2.conf (Y/I/N/O/D/Z) [default=N] ? dpkg: error processing package apache2 (--configure):
 end of file on stdin at conffile prompt

Since there isn't enough information in your report to differentiate between a local configuration problem and a bug in Ubuntu, I'm marking this bug as Incomplete.

If indeed this is a local configuration problem, you can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

Or if you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New.
