[Bug 1892160] Re: Ubuntu 20 upgrade 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 before 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!
