[Bug 1828589] Re: can not upgrade to ubuntu 19

[Steve Beattie]

Thanks for taking the time to report this bug and helping to make Ubuntu
better. We appreciate the difficulties you are facing, but this appears
to be a "regular" (non-security) bug.  I have unmarked it as a security
issue since this bug does not show evidence of allowing attackers to
cross privilege boundaries nor directly cause loss of data/privacy.
Please feel free to report any other bugs you may find.

Title:
  can not upgrade to ubuntu 19

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

Bug description:
  Invalid package information

  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.
