[Bug 1981672] Re: apt phased out broken code, missing documentation to opt out

[Lenin]

1) We have like 100+ Ubuntu 22.04 machines, the updates get installed
with aptitude (via aptitude-robot). No pinning, but one held package
(nvtop) (on 66% of machines).

2) Here's just one package example:
$ apt policy samba-libs
samba-libs:
  Installed: 2:4.15.5~dfsg-0ubuntu5.1
  Candidate: 2:4.15.5~dfsg-0ubuntu5.1
  Version table:
 *** 2:4.15.5~dfsg-0ubuntu5.1 500 (phased 40%)
        500 http://ubuntu.ethz.ch/ubuntu jammy-updates/main amd64 Packages
        500 http://ubuntu.ethz.ch/ubuntu jammy-proposed/main amd64 Packages
        100 /var/lib/dpkg/status
     2:4.15.5~dfsg-0ubuntu5 500
        500 http://ubuntu.ethz.ch/ubuntu jammy/main amd64 Packages

3) $ cat sources.list
deb     http://ubuntu.ethz.ch/ubuntu jammy main restricted universe multiverse
deb-src http://ubuntu.ethz.ch/ubuntu jammy main restricted universe multiverse
deb     http://ubuntu.ethz.ch/ubuntu jammy-security main restricted universe multiverse
deb-src http://ubuntu.ethz.ch/ubuntu jammy-security main restricted universe multiverse
deb     http://ubuntu.ethz.ch/ubuntu jammy-updates main restricted universe multiverse
deb-src http://ubuntu.ethz.ch/ubuntu jammy-updates main restricted universe multiverse
deb     http://ubuntu.ethz.ch/ubuntu jammy-proposed main restricted universe multiverse
deb-src http://ubuntu.ethz.ch/ubuntu jammy-proposed main restricted universe multiverse

sources.list.d 404 (all empty)

4) nothing there...

It's so little, I just copy pasted it here. Hope that's fine.

Title:
  apt phased out broken code, missing documentation to opt out

Status in apt package in Ubuntu:
  Incomplete

Bug description:
  Having the configuration at
  https://discourse.ubuntu.com/t/phased-updates-in-apt-in-21-04/20345/24
  it fails to work.

  The phased updates get distributed on some hosts anyways for 22.04.

  Please properly document and test this, and provide a working
  configuration to opt out from phased updates.
