Manage /etc/apt/preferences in the same way as /etc/sources.list

[wmarler]

Debian apt-get will look in both /etc/apt/preferences as well as files in /etc/apt/preferences.d for pinning information. This module will purge /etc/apt/sources.list, but will not touch /etc/apt/preferences.

I have code to address this issue, though there is an underlying issue with 'apt-get upgrade' that requires a valid entry in /etc/apt/preferences to function. An empty file, or a file with a single comment, will throw an error (see Debian bug 641245). It makes the Puppet solution look a little sloppy.

If you read through the 641245 you'll notice that it's not a bug, it's defined behaviour in Apt.

If you want to add a comment to Apt you simply start a line with Explanation: the rest of the comment.

Therefor you can do something like this:

file { '/etc/apt/preferences':
  ensure => file,
  content => 'Explanation: preferences are being managed by Puppet in preferences.d',
}

If you have a pull request to fix this I'd be more than willing to review it and help out with the tests.

Wrong. If you had bothered to test you would have seen that this commenting
style does not work. See

Wrong.

You pointed us to bug 641245 which has nothing to do with empty files or the Explanation tag not working, it has to do with a faulty comment style which led me to assume you tried the # style of comments.

If you had bothered to test

I did test. However my testing machines are Debian Unstable / Sid and the issue has already been solved there.

I'm just another community member trying to help people get their fixes in. I do this in my free time to try and help others out, no need to be rude.

As I said before, if you have code to fix this I'm more than happy to look it over and see if I can get it merged in.

I am sorry that I was snarky and said "if you'd bothered to test" -- I do
not use Jesse or Sid (I'm working with production machines), and it didn't
occur to me that you would. I'm glad to hear the fix makes my bug report
seem non-reproducible, and I appreciate you donating your time.

I am sorry to say I don't have a fix to contribute anymore : (.

Please note that in Squeeze and Wheezy (at least as of today) the apt
version is still too old, and having either an empty preferences file, one
with #-style comments, or one with a single "Explanation: ..." style
comment will not work. Using a single "Explanation: ..." style comment will
work, as long as it's followed with "Package: " line. The
"" does not have to be a valid package.

@wmarler I just pushed PR #240 . Could you test it and see if it works for you?
