[Bug 1895591] Re: I'm trying to upgrade ubuntu from 18.4 to 20 with terminal command and not working

[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!

Title:
  I'm trying to upgrade ubuntu from 18.4 to 20 with terminal command and
  not working

Status in ubuntu-release-upgrader package in Ubuntu:
  Incomplete

Bug description:
  After updating your package information, the essential package 
  'ubuntu-minimal' could not be located. This may be because you have 
  no official mirrors listed in your software sources, or because of 
  excessive load on the mirror you are using. See /etc/apt/sources.list 
  for the current list of configured software sources. 
  In the case of an overloaded mirror, you may want to try the upgrade 
  again later.
