[Bug 1959023] Re: upgrade 16 to 18 fails

[Brian Murray]

Reviewing the log file, /var/log/dist-upgrade/main.log, from your
upgrade attempt there was a failure to communicate with the mirror of
the Ubuntu archive which you use. This could either be due to an issue
with your connection to the mirror or with the mirror itself.
Regardless, this is an issue you'll need to sort out by fixing your
network connection or switching to a different mirror of the Ubuntu
archive before the upgrade can complete. If after resolving the
communication error with the mirror you are still unable to upgrade to a
new release of Ubuntu please open a new bug report so we'll have fresh
log files. Thanks and good luck!
