[Bug 1725359] Re: release detection relies on lsb-release

[Scott]

Thanks for the guidance, I was able to upgrade after doing a couple of
things. First I changed the file names from Xenial to Zesty in
/etc/apt/sources.list. After that I tried to upgrade the dist to 17.10
but it was going to do a partial upgrade which I heard is not a good
thing to do. I cancelled the upgrade  ran the following commands in the
terminal: and

Title:
  release detection relies on lsb-release

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

Bug description:
  ubuntu-release-upgrader uses lsb-release to determine the version of
  Ubuntu the system is running, however no double checking is done.  As
  we can see in bug 1725176, the user installed the version of lsb-
  release from Ubuntu 17.04 although they are running Ubuntu 16.10. The
  release-upgrader tries to upgrade them from zesty to artful but this
  fails as their /etc/apt/sources.list is full of yakkety entries and
  everything ends up being disabled.

  The release upgrader should likely confirm they either have their
  releases lsb-release installed or double check that their
  /etc/apt/sources.list matches the release lsb-release returns.

  I'll also use this as a tracking bug to find out how many people this
  is affecting.
