[Aptitude-devel] Bug#934541: aptitude: upgraded a package to experimental without notice, though SolutionCost has "safety" first

[Vincent Lefevre]

Control: found -1 0.8.12-1

This bug still occurs. During an upgrade last month:

Aptitude 0.8.12: log report
Mon, Jan 27 2020 13:16:20 +0100
[...]
[UPGRADE] bash-completion:amd64 1:2.9-1 -> 1:2.10-1

[UPGRADE] ksh:amd64 2020.0.0-2.1 -> 2020.0.0-4
[UPGRADE] lzip:amd64 1.21-5 -> 1.21-6
[UPGRADE] mksh:amd64 57-4 -> 57-5
[UPGRADE] opera-stable:amd64 66.0.3515.36 -> 66.0.3515.44
[UPGRADE] python-apt:amd64 1.8.5 -> 1.8.6

[UPGRADE] python3-apt:amd64 1.8.5 -> 1.8.6
[UPGRADE] qpdf:amd64 9.1.0-1 -> 9.1.1-1

but python-apt-common comes from experimental:

python-apt (1.9.5) experimental; urgency=medium

  * SECURITY REGRESSION: crash with ubuntu-release-upgrader (LP: #1860606)
    - apt/cache.py: make allow_unauthenticated argument to
      fetch_archives() optional.

  [ Julian Andres Klode ]
  * Really bump aptdaemon break (to 1.1.1+bzr982-0ubuntu31)

while both python-apt and python3-apt were upgraded to unstable
as expected.

AFAIK, I did the upgrade of these packages via the TUI.

Note with "apt-show-versions -u", currently:

python-apt-common:all/experimental *manually* upgradeable from 1.9.5 to 1.9.7
