[Touch-packages] [Bug 1267059] Re: "Unattended-Upgrade::Remove-Unused-Dependencies" does not work

2015-05-12 Thread Lars Heide
As there has been confusion about this apparently:

Marking the packages for upgrade

line 1194: "mark_upgrade()"

is not the same as upgrading them. The upgrade only happens after the
changes are commited:

line 392: "res = cache.commit(install_progress=iprogress)"

The output of "is_auto_removable" only changes after that AFAIK.

[Touch-packages] [Bug 1267059] Re: "Unattended-Upgrade::Remove-Unused-Dependencies" does not work

2015-05-12 Thread Lars Heide
APT::Periodic::AutocleanInterval is kinda documented in
/etc/cron.daily/apt

#  APT::Periodic::AutocleanInterval "0";
#  - Do "apt-get autoclean" every n-days (0=disable)

>From what I read from the code, it does just that. According to the man
page "autoclean clears out the local repository of retrieved package
files".

In what way is that equivalent to "autoremove"?

Besides: The original authors intent "to auto-remove only those packages
that have been made redundant by the current set of updates" fails.
Please see comment #7:

The author checks for auto-removable packages, then marks the new
packages as "to install" and then checks again for autoremovable
packages and then tries to remove the difference of those two sets. But
the two sets are always the same, the resulting set is therefore empty.
Without actually installing the new packages, the solver does not return
a different set of auto-removable packages.

[Touch-packages] [Bug 1267059] Re: "Unattended-Upgrade::Remove-Unused-Dependencies" does not work

2014-09-18 Thread Lars Heide
I checked and apparently now_auto_removable and pkgs_auto_removable are
always the same, as "is_auto_removable" only returns different results
_after_ the packages have actually been upgraded. Just marking them does
apparently not change the output of is_auto_removable(). I tried to use
the ProblemResolver but I didn't get the output of is_auto_removable()
to change.

One possible solution is to actually upgrade the packages and then check
for autoremovability, then you can make it works as intended. My
original patch implemented only an autoremove (same as "apt-get
autoremove").

[Touch-packages] [Bug 1267059] Re: "Unattended-Upgrade::Remove-Unused-Dependencies" does not work

2014-09-18 Thread Lars Heide
Actually I just saw that it is semi fixed in 14.04 in the way that

now_auto_removable-pkgs_auto_removable

now reads

now_auto_removable - pkgs_auto_removable

which is also wrong, as

now_auto_removable = set([pkg.name for pkg in cache
  if pkg.is_auto_removable])
and

pkgs_auto_removable = set([pkg.name for pkg in cache
   if pkg.is_auto_removable])

are apparently the same, therefore substracting them from each other is
always empty.

2014-09-17 Thread Lars Heide
This thing seems to be broken in 2 ways (on 12.04 at least):

A) Its checking internally for the wrong variable ( 
now_auto_removable-pkgs_auto_removable instead of  now_auto_removable-pkgs) :
Do this and it will actually tell you the packages that are to be removed.

B) It does not actually remove the packages because there is no call to
cache.commit()

I have included a patch. I don't know if there is some intended
behaviour this is breaking though.

Title:
  "Unattended-Upgrade::Remove-Unused-Dependencies" does not work

Status in “unattended-upgrades” package in Ubuntu:
  Confirmed

Bug description:
  I have a system that runs unattended-upgrades just fine. Now i want to
  automate removal of old kernels and kernel header packages that are
  accumulating otherwise. So i set 'Unattended-Upgrade::Remove-Unused-
  Dependencies "true";'. But it doesn't work.

  
  Details: Lots of stuff pending autoremoval:

  $ apt-get --assume-no autoremove 
  Reading package lists... Done
  Building dependency tree   
  Reading state information... Done
  The following packages will be REMOVED

  Note that the majority of these packages have been installed by
  unattended-upgrades from precise-security.

  According to the comments within/etc/apt/apt.conf.d/50unattended-
  upgrades, this should automate autoremoval:

// Do automatic removal of new unused dependencies after the upgrade
// (equivalent to apt-get autoremove)
Unattended-Upgrade::Remove-Unused-Dependencies "true";

  but nothing happens (note the line "Packages that are auto removed: ''
  ":

  $ unattended-upgrades --debug --dry-run
