(Unattended-upgrades) Apparently I'm running Debian... Again.

Okay, let's install unattended-upgrades for a new-old headless Devuan box... This should just-work like it has for the last 20 years on Debian, right?

Ahh. I see. This again.

Look, I realise it's a small team and all that, but can we please at least try to get the name of the distro right?
A bootloader that still says "Debian" is kind of embarrassing, but harmless. Borking things like unattended-upgrades is going to get someone pwned.

Best of all, according to the bugtracker this was supposedly fixed in 2017. Yet here it is again.

Re: (Unattended-upgrades) Apparently I'm running Debian... Again.

I have never used unattended upgrades. Could the devuan 3.1 release notes shed a bit more light on this issue?

Changing the ID of the operating system.

- This point-release (3.1.0) fixes a bug in the last release that
   showed "Debian" in the boot menu instead of "Devuan".

   If you need the system to identify itself as Debian, you can edit
   /etc/os-release to show ID=debian. This may be needed for third-party
   software that expects to see debian.

How many headless boxes do you administer? If you don't like needing to ssh into each one to apply updates, and want your machines to keep themselves up to date, mail you with results and schedule their own reboots for when there are no users logged in, unattended-upgrades is for you.

It's been in main at least as far back as etch, so it's not exactly exotic and I'm fairly confident I'm not the only one using it.

It sheds light on the grub menu problem, but this being a new (post point-release) install it already has that fix.

PRETTY_NAME="Devuan GNU/Linux 3 (beowulf)"
NAME="Devuan GNU/Linux"
VERSION_ID="3"
VERSION="3 (beowulf)"
VERSION_CODENAME=beowulf
ID=devuan
ID_LIKE=debian
HOME_URL="https://www.devuan.org/"
SUPPORT_URL="https://devuan.org/os/community"
BUG_REPORT_URL="https://bugs.devuan.org/"

This is another problem of the same class all right though, i.e. rolling debian packages into the repos without checking them for debianisms.

That's not how it works: https://dev1galaxy.org/viewtopic.php?id=3192

So you do understand how to make unattended-upgrades work then? I think the community would appreciate a quick HowTo thread in the Freedom Hacks section more than this pointless rant.

Yes yes, perhaps I should have said "let the automation pull packages from Debian without checking them for functionality on Devuan." The result is the same.

Head_on_a_Stick wrote:

Anyone who has a passing familiarity with sed can make unattended-upgrades work. Perhaps somebody should teach amprolla the same trick.
Likewise anyone who can search a bugtracker can realise that pulling down such packages from Debian without any squishy eyeballs on them is going to reintroduce bugs just like this one.

Frankly I suspect what the community would appreciate even more would be a little look into where that fix committed 4 years ago wandered off to in the first place.

On a completely off-topic note, you're extremely unlikely to see me in the "Freedom Hacks" sub, ever. The pretentious name alone is enough to keep me away.

I dont run any headless boxes. But it sounds like a good idea if you have a network of many systems you need to look after. Sorry i couldnt be of any help. Maybe file a bug report again ??

No worries, and no apology needed. This was more a "(loudly) bring it to somebody's attention that this stuff is slipping through again" than a "how do I fix it". Fixing it is easy, it's the "making sure 'debian' doesn't keep slipping into our default configs and breaking things" bit that I'm after.

dice wrote:

Yeah, I'll get to that just as soon as I get around to figuring out how to report bugs... Round tuits are in short supply right now.

Re: (Unattended-upgrades) Apparently I'm running Debian... Again.

The steps for a bug report are almost as simple as your fixing of that file:

  1. find out which package is concerned (unattended-upgrades)

  2. find out which version of that package you'r using (1.11.2)

  3. send an email to submit@devuan.org with a useful subject, and the body starting "formally" with 2 lines:

    Package: unattended-upgrades
    Version: 1.11.2

    then followed by a polite and useful treatise outlining the issue and preferrably including a patch that resolves it.

In this particular case, the "bug" is lack of maintaner effort to upgrade the fork of unattended-upgrades. Therefore beowulf got committed with the debian package version.

Your patch will go part of the way towards upgrading the forked package, which also needs any other changes since the last fork version, 0.93.1+vua2.0, including any adaption to the current package building pipline.

As it happens, the maintainer role for that forked package is currently vacant.

Re: (Unattended-upgrades) Apparently I'm running Debian... Again.

I'm a not-especially-experienced user trying to figure out why my Devuan machines are not automatically updating themselves, or at least prompting me to do so.  (I assumed this would most likely happen by default, as on Ubuntu, from which I migrated, so it took me a while to notice that they weren't.)  I've searched for further information, and your discussion here is the best lead I've found: it seems, I think, that the unattended-upgrades package should do this for me, but doesn't, due to a bug.

I understand from the above that there's some straightforward fix that can be applied by editing /etc/apt/apt.conf.d/50unattended-upgrades and that it can be implemented by anyone with a passing familiarity with sed (which I have, barely).  But I don't understand what that fix actually *is*.

Could someone please tell me explicitly how to fix this bug?

Edit /etc/apt/apt.conf.d/50unattended-upgrades and change the Debian repository references to the correct Devuan equivalents.

Re: (Unattended-upgrades) Apparently I'm running Debian... Again.

Tested this at beowulf and after

aptitude show unattended-upgrades
Paket: unattended-upgrades                      
Version: 2.8
vi 50unattended-upgrades
%s/debian/devuan/g
%s/Debian/Devuan/g
:wq
unattended-upgrade --debug | wc -l

189 lines showed up (many) of debs, which can be upgraded.
In Devuan beowulf the problem is not fixed yet

Besides, if somebody needs a "freedom hack" post for a word replacement as obvious as this, I expect they probably need spoon-feeding and burping as well.

Re: (Unattended-upgrades) Apparently I'm running Debian... Again.

Steve,

Apparently the issue with unattended-upgrades is that Devuan support is in the Debian source, but the source also needs to be recompiled on a Devuan system.

I have added preliminary support for us doing that to the Devuan jenkins instance. Could you please test these artifacts and report back?

Thanks

Works fine on beowulf as far as a cursory test in a VM. Not so much on chimaera if one is using codename matching though...

I see the config template for Debian (50unattended-upgrades.Debian) references release as ${distro_codename}, and AFAICT from the python script, that's pulled from the output of lsb_release.
The config for Devuan does not (though it retains the reference to /etc/debian_version, which is nonsensical on Devuan), instead including hardcoded lines for beowulf.
The relevant (main, security) lines are also commented in the Devuan config, whereas for Debian they are not. Minor detail and all.

IMO since lsb_release returns correct information on Devuan, it would make sense to use ${distro_codename} by default here as well. Also changing /etc/debian_version to /etc/devuan_version for less confusion, since the former doesn't actually contain a release codename.

TBH I'm a little confused that the Devuan config deviates so far from the Debian version to begin with - all that's really needed is s/Debian/Devuan/g and some minor cleanup of the comments.

It may date from a few years ago when lsb-release returned confusing data on Devuan to fix UEFI boot. That is now resolved.

If you have a better/improved default config for Devuan, could you submit it to Debian's BTS please?

Many thanks.

I use unattended upgrades to install security upgrades on both my main PC and my mail server.

I didn't find it that difficult to get working.

1. Install package

2. Consult man page

man unattended-upgrades

read the lines

CONFIGURATION
       The  configuration  is  done  via  the  apt  configuration  mechanism.  The  default  configuration  file can be found at
       /etc/apt/apt.conf.d/50unattended-upgrades

3. Open (as root/sudo) the file  /etc/apt/apt.conf.d/50unattended-upgrades and configure.
The file is largely self-documenting.

This includes changing the default distribution and package.

This is my fixed/working version. I suspect its unchanged (apart from changing ascii to chimaera in line 43) since I used ascii.

// Unattended-Upgrade::Origins-Pattern controls which packages are
// upgraded.
//
// Lines below have the format format is "keyword=value,...".  A

//   o,origin        (eg, "Devuan")
//   n,codename      (eg, "ascii", "ascii-updates")
//     site          (eg, "deb.devuan.org")
// The available values on the system are printed by the command
// "apt-cache policy", and can be debugged by running

It might be nicer if the Chimaera version included Devuan/Chimaera/security defaults (my line 43):

       "o=Devuan,n=chimaera-security"; 

But not sure its really worth pestering our admins to do this every time Debian change it upstream as there are other options in the config you might want to change anyway ( I don't do auto reboots or install non-security ungrades, I do ask it to email me when upgrades happen) though a mention in the release notes might help as at the very least you do need to change that line, or it's equivalent, to include 'chimaera' when upgrading.

I run apt both on my mail server and my main PC via 0anacron and apt-compat in /etc/cron.daily so it should check for updates daily. For a server you could just call it directly from cron, however as I often hibernate rather than reboot my main PC overnight I also get it to check for updates on resume (cron doesn't run jobs called when the computer is turned off at the designated time).

This is my fixed/working version. I suspect its unchanged (apart from changing ascii to chimaera in line 43) since I used ascii.

If your install dates back to ascii (and you haven't let dpkg clobber the config files) you would have correct distro name, as this predates the fix getting lost and the package reverted to upstream Debian.

That's kinda my point WRT using ${distro_codename} instead of a hardcoded release. That's how Debian does it, and it allows unattended-upgrades to track the new release after a dist-upgrade with no manual changes to its configuration at all.

Ditto for the devuan-security line, I see no reason not to use ${distro_codename} there either, unless to create more packaging work.

Surely that would only make sense if I wanted to upgrade immediately 'testing' became 'stable'?
I'm far too conservative to want to do that - I'd rather wait a decent interval and let other find out for me what problems are surfaced.
Note the latest fubar with Windows ( https://www.theregister.com/2023/01/16/ … e_scripts/).
This is also why I only update security patches immediately.

No, that's what "archive" (a=foo) matching is for.

a=stable will track whatever release is currently marked as stable (so it's liable to silently start pulling in packages from a new stable release as soon as it becomes available).
n=<codename> will track <codename> forever until you change it manually, regardless of unstable/testing/stable status.
n=${distro_codename} does the same, except that it uses lsb_release to determine which release codename you are currently running. When (and only when) you switch to a different release (i.e. change your sources and do a manual dist-upgrade), lsb_release picks it up, nobody needs to look at that file.

That last one has been the "safe" default in Debian for a long time now, and AFAICT the only reason it isn't on Devuan is that lsb_release was broken for a while (returning Debian release names).
IIRC lsb_release in turn was broken to work around yet another "we're 99% Debian but trying to pretend we're not" class bug. Of course. roll

All that is now fixed, so I see no reason not to put this trivial bit of automation back. smile
