ubuntu-distro-info shows the current development series as "latest development" and "supported stable version" at the same time

[Nobuto Murata]

The current development series (cosmic as of today) should not be listed up as "supported stable versions".

$ ubuntu-distro-info --date 2018-06-27 --devel -f
Ubuntu 18.10 "Cosmic Cuttlefish"

$ ubuntu-distro-info --date 2018-06-27 --supported -f
Ubuntu 14.04 LTS "Trusty Tahr"
Ubuntu 16.04 LTS "Xenial Xerus"
Ubuntu 17.10 "Artful Aardvark"
Ubuntu 18.04 LTS "Bionic Beaver"
Ubuntu 18.10 "Cosmic Cuttlefish" <<< should not be here because it's a development series still

$ apt policy distro-info
distro-info:
  Installed: 0.18
  Candidate: 0.18
  Version table:
 *** 0.18 500
        500 http://jp.archive.ubuntu.com/ubuntu bionic/main amd64 Packages
        100 /var/lib/dpkg/status

$ date +%F
2018-06-27

$ grep cosmic /usr/share/distro-info/ubuntu.csv
18.10,Cosmic Cuttlefish,cosmic,2018-04-26,2018-10-18,2019-07-18

So the release date of "cosmic" is 2018-10-18 in distro-info-data, so cosmic as the current development series should not be listed with `ubuntu-distro-info --supported` because it's before the date as of today.

$ ubuntu-distro-info -h
...
  -d --devel latest development version

      --supported list of all supported stable versions
...

Status changed to 'Confirmed' because the bug affects multiple users.

The information actually comes from the distro-info-data package, not distro-info. What version of distro-info-data do you have installed?

[Brian Murray (brian-murray)]

Oh, I didn't notice how old this - it predates the SRU of distro-info-data to Artful so I'm going to set this to Fix Released.

[Nobuto Murata (nobuto)]

I didn't mean that way. Let me set it back to ditro-info package and update the title and description.

[Nobuto Murata (nobuto)]

I think we need a condition "date >= x.release" like an attached diff (it's only for python though).

[Ubuntu Foundations Team Bug Bot (crichton)]

The attachment "date_x_release.diff" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

[Brian Murray (brian-murray)]

How is the development release of Ubuntu unsupported? It is still a supported release of Ubuntu, we work to fix bugs on it, although it may not be a stable one.

[Nobuto Murata (nobuto)]

Yes, that totally depends on the definition of the option "--supported list of all supported stable versions". I was confused initially, but if that's by design, we don't need to change the behavior. Sorry for the noise.

[Dan Watkins (oddbloke)]

As nobuto notes, the man page says "list of all supported stable versions"; so either the functionality or the man page needs to be updated.

[Stefano Rivera (stefanor)]

Updating the man page (and --help)

[Launchpad Janitor (janitor)]

This bug was fixed in the package distro-info - 1.1

---------------
distro-info (1.1) unstable; urgency=medium

  * Man pages and help: Clarify that --supported includes development releases
    (Closes: #902167, LP: #1727751)
  * Update Python module to satisfy pylint 2.11 (Closes: #998598)
  * Python: Drop object inheritance in classes, we no longer need to support
    2.7.
  * Re-black python.
  * Bump Standards-Version to 4.6.0, no changes needed.
