  in configuration file /etc/apt/apt.conf.d/50unattended-upgrades,
  unattended-upgrade is unable to remove packages that become unused in 
conjunction with updating by other software such as update-manager or apt 
full-upgrade. This is because unattended-upgrade compares the list of unneeded 
packages before and after it upgrades packages to detect which packages are new 
unused ones.

  Consequently, if user installs new kernels using e.g. update-manager,
  the excessive kernels will not be removed by unattended-upgrade, and
  eventually (small) /boot will become full.

  Expected behavior: handle removing of unused packages differently at

[Brian Murray]

Well this does work in Trusty, Ubuntu 14.04, perhaps this is a
regression in support "Never-MarkAuto-Sections"?

One thing to note is that using 'apt-mark' I saw that vino was marked as
manual on Ubuntu 14.04, but automatic on Ubuntu 16.04.

[Touch-packages] [Bug 1624644] Re: By default settings unattended-upgrade is unable to automatically remove packages that become unused in conjunction with updating by other software.

[Julian Andres Klode]

There were like 3 versions of metapackage auto removal, I don't remember
exactly.

I think in the beginning, we just autoremovef everything.

Then we did not mark packages as automatically installed if installed by
a meta package.

Then we moved to moving the auto bit on uninstall, but maybe only if the
meta is removed due to a conflict, and not when manually.

I only followed this on the sidelines.

I ran the same metapackage removal test on Xenial, so if Julian is right
and this is a regression its a rather old one. Do you have any more
details about your thoughts Julian?

I ran this on zesty, but if meta packages are handled differently then
I could imagine a similar
case when meta packages are not involved.

I had the opposite situation in my mind. People would remove packages
which are not auto removable, like ubuntu-desktop (for example because
something ubuntu-desktop depends on is acting badly) and then many
package in ubuntu-desktop's dependency change become auto removable:

$ sudo apt-get remove ubuntu-desktop
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages were automatically installed and are no longer required:
  a11y-profile-manager-indicator activity-log-manager adium-theme-ubuntu
  aisleriot app-install-data-partner apturl apturl-common baobab bluez-cups
...
  xorg
Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:
  ubuntu-desktop
0 upgraded, 0 newly installed, 1 to remove and 7 not upgraded.
After this operation, 46,1 kB disk space will be freed.
Do you want to continue? [Y/n]

It is a simpler problematic situation than the one I originally mentioned, u-u
would remove software which is probably in use, no additional software is
broken.

  When using default settings for unattended-upgrade i.e.

  in configuration file /etc/apt/apt.conf.d/50unattended-upgrades,
  unattended-upgrade is unable to remove packages that become unused in 
conjunction with updating by other software such as update-manager or apt

unused ones.

[Touch-packages] [Bug 1624644] Re: By default settings unattended-upgrade is unable to automatically remove packages that become unused in conjunction with updating by other software.

[Brian Murray]

@Balint re "@Jarno: IMO Unattended-Upgrade::Remove-Unused-Dependencies
is already a risky option and I don't recommend enabling it because it
may remove packages which are not used according the to package-
dependency chain but which users rely on using software that is not
packaged."

Could you give me an example of how people would install dependencies
for software that is not package that would also set the
"is_auto_removable" flag in the apt cache to True? I can't think of a
situation like this.

[Touch-packages] [Bug 1624644] Re: By default settings unattended-upgrade is unable to automatically remove packages that become unused in conjunction with updating by other software.

[Brian Murray]

The get_auto_removable function in unattended-ugprades just checks to
see if the package has the "is_auto_removable" flag set. So setting
"Unattended-Upgrade::Remove-Unused-Dependencies" to "true" will produce
the same outcome as using "sudo apt autoremove" e.g.:

bdmurray@clean-xenial-amd64:~$ sudo apt autoremove
[sudo] password for bdmurray:
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages will be REMOVED:
  libllvm3.8 libmircommon5 libsnapd-glib1 linux-headers-4.4.0-31 
linux-headers-4.4.0-31-generic linux-image-4.4.0-31-generic
  linux-image-extra-4.4.0-31-generic snap-confine snapd-login-service 
ubuntu-core-launcher

bdmurray@clean-xenial-amd64:~$ sudo unattended-upgrade --dry-run
/usr/bin/dpkg --status-fd 9 --force-depends --remove libllvm3.8:amd64 
libmircommon5:amd64 snapd-login-service:amd64 libsnapd-glib1:amd64 
linux-headers-4.4.0-31-generic:amd64 linux-headers-4.4.0-31:all 
linux-image-extra-4.4.0-31-generic:amd64 linux-image-4.4.0-31-generic:amd64 
snap-confine:amd64 ubuntu-core-launcher:amd64
/usr/bin/dpkg --status-fd 11 --configure --pending

So I think the question here is whether or not we think it is safe to
run autoremovals without user interaction.

Anyway, in my view
Unattended-Upgrade::Remove-Unused-Dependencies "true";
would be the default setting to have now, and advanced users should mark the 
dependencies of their unpackaged software as "manual".

It will remove the third newest kernel, but later, when the one you
installed by "apt install" will become third newest, it will not be
removed automatically. That is by design.

No, this is not the behavior I observed. After installing a new kernel
version via update-manager or 'sudo apt-get install' on Ubuntu 16.04, 'sudo
apt autoremove' does the right thing and wants to remove my third newest
kernel.

[Jarno Suni]

Brian, however, as you installed the kernel by apt-get install, the
kernel becomes manually installed, and will not later be removed by
'sudo apt autoremove', unless you change it to be marked as
automatically installed.

I question the use of 'sudo apt autoremove' in this case. If its action was the 
desired one, setting 
Unattended-Upgrade::Remove-Unused-Dependencies "false";
would be the setting to use, instead of the current default
Unattended-Upgrade::Remove-New-Unused-Dependencies "true";
Balint Reczey tries to explain in #11 why that setting is not desired.

[Touch-packages] [Bug 1624644] Re: By default settings unattended-upgrade is unable to automatically remove packages that become unused in conjunction with updating by other software.

[Brian Murray]

I found the description somewhat confusing because 'Unattended-Upgrade
::Remove-New-Unused-Dependencies "true"; doesn't actually exist in
/etc/apt/apt.conf.d/50unattended-upgrades, rather that's the default
setting in unattended-upgrades since 0.90. Regardless, I was able to
recreate the issue on an Ubuntu 16.04 system via the following
procedure.

1) Use apt-get install to install a new kernel (linux-image-generic)
2) Run unattended-upgrades (observe "no pending auto-removals")

However, running 'sudo apt autoremove' does want to remove an old
kernel.

Bug description:
  When using default settings for unattended-upgrade i.e.
  Unattended-Upgrade::Remove-Unused-Dependencies "false";
  # default "false"
  Unattended-Upgrade::Remove-New-Unused-Dependencies "true";
  # default "true"
  in configuration file /etc/apt/apt.conf.d/50unattended-upgrades,
  unattended-upgrade is unable to remove packages that become unused in 
conjunction with updating by other software such as update-manager or apt 
full-upgrade. This is because unattended-upgrade compares the list of unneeded 
packages before and after it upgrades packages to detect which packages are new 
unused ones.

  Consequently, if user installs new kernels using e.g. update-manager,
  the excessive kernels will not be removed by unattended-upgrade, and
  eventually (small) /boot will become full.

  Expected behavior: handle removing of unused packages differently at
  least until other package management software installed by default can
  handle removing of new unused packages.

E.g. Apt could have --autoremove-new option which would work with apt
and apt-get
