[Bug 1554099] Re: Changing what action for security updates unusable

[Brian Murray]

I'm pretty sure this is the source of the problem, software-properties
looks at Apt configuration options, which are the following in a fresh
install of Xenial.

bdmurray at clean-xenial-amd64:~$ grep -r "APT::Periodic" /etc/apt/*
/etc/apt/apt.conf.d/10periodic:APT::Periodic::Update-Package-Lists "1";
/etc/apt/apt.conf.d/10periodic:APT::Periodic::Download-Upgradeable-Packages "0";
/etc/apt/apt.conf.d/10periodic:APT::Periodic::AutocleanInterval "0";
/etc/apt/apt.conf.d/20auto-upgrades:APT::Periodic::Update-Package-Lists "1";
/etc/apt/apt.conf.d/20auto-upgrades:APT::Periodic::Unattended-Upgrade "1";

So we have autodownload set to 0, and unattended set to 1.  Looking at
the code in SoftwareProperties.py we see:

147     if apt_pkg.config.find_i(softwareproperties.CONF_MAP["autoupdate"]) > 0:
148         # Autodownload
149         if apt_pkg.config.find_i(softwareproperties.CONF_MAP["unattended"]) == 1\
150            and apt_pkg.config.find_i(softwareproperties.CONF_MAP["autodownload"]) == 1 :
151             return softwareproperties.UPDATE_INST_SEC
152         elif apt_pkg.config.find_i(softwareproperties.CONF_MAP["autodownload"]) == 1 and  \
153              apt_pkg.config.find_i(softwareproperties.CONF_MAP["unattended"]) == 0:
154             return softwareproperties.UPDATE_DOWNLOAD
155         elif apt_pkg.config.find_i(softwareproperties.CONF_MAP["unattended"]) == 0 and \
156              apt_pkg.config.find_i(softwareproperties.CONF_MAP["autodownload"]) == 0:
157             return softwareproperties.UPDATE_NOTIFY
158         else:
159             return None

So somebody's created a situation we hadn't planned on.

Title:
  Changing what action for security updates unusable

Status in software-properties package in Ubuntu:
  Confirmed

Bug description:
  Open software-properties.

  Important security updates is not enabled on install.

  Secondly - it is not possible to change the action to take with
  security updates even if it is enabled (note: I enabled security
  updates, reloaded cache and restarted software-properties before
  trying to change the action)

  eg - the Display Immediately/Download automatically/Download and
  install automatically
