Title:
  Blacklisted packages are included in the "upgradable origin", while
  they should not

  Fix Released
Status in unattended-upgrades package in Ubuntu:

Bug description:
  [Impact]

   * Reports from u-u incorrectly list packages from non-upgradable
  origins as "Packages with upgradable origin but kept back"

   * Listing the packages incorrectly is a result of
  is_pkgname_in_blacklist() having a side effect and removing the side
  effect is part of fixing LP: #1396787 which fix is also being SRU-d.

   * The fix is removing the side effect of is_pkgname_in_blacklist()

  [Test Case]

   * There is a build-time test in test/test_blacklisted_wrong_origin.py
   * To reproduce the original problem set up a system where all security 
updates are installed but ebtables (from bionic-updates) is not updated:
  $ sudo unattended-upgrade  --verbose
  Initial blacklisted packages:
  Initial whitelisted packages:
  Starting unattended upgrades script
  Allowed origins are: o=Ubuntu,a=bionic, o=Ubuntu,a=bionic-security, 
o=UbuntuESM,a=bionic
  No packages found that can be upgraded unattended and no pending auto-removals
  $ sudo apt upgrade

  The following packages will be upgraded:
    apt apt-utils ebtables initramfs-tools initramfs-tools-bin 
initramfs-tools-core libapt-inst2.0 libapt-pkg5.0
    liblxc-common liblxc1 libpython3-stdlib lxcfs lxd lxd-client netplan.io

  Abort.

  * blacklist ebtables, set up emails from u-u, then run u-u again:
  $ sudo echo 'Unattended-Upgrade::Package-Blacklist {"ebtables";};' > 
/etc/apt/apt.conf.d/51unattended-upgrades-blacklist-ebtables
  $ sudo echo 'Unattended-Upgrade::Mail "root";' > 
/etc/apt/apt.conf.d/51unattended-upgrades-mail
  $ sudo unattended-upgrade  --verbose
  Initial blacklisted packages: ebtables
  Initial whitelisted packages:
  Starting unattended upgrades script
  Allowed origins are: o=Ubuntu,a=bionic, o=Ubuntu,a=bionic-security, 
o=UbuntuESM,a=bionic
  Packages that will be upgraded:

  * Observe ebtables listed as being kept back and having upgradable origin 
with buggy u-u:
  $ sudo cat /var/mail/mail
  ...
  Packages with upgradable origin but kept back:
   ebtables=20
  ...

  * Upgrade u-u to a fixed version and run it, observing ebtables to be
  not listed as having upgradable origin

  [Regression Potential]

   * Regressions may make packages incorrectly missing from u-u's
  report, but the autopkgtests also cover that to some extent.
