Upgradeing to the next stable on arm's in general will likely be done by 
installing the system on a u-sd card with dd, from an image built by the 
linuxcnc people, and will continue to be until such time as debian also 
supports the rt kernel flavors, which isn't even done for the *86 stuff. 
Building that image is a major project, which is why our *86 machines 
are still running wheezy. Might have 10 jessie installs, all but mine on 
*86 machines. Not debians fault, nor am I blaming debian, its a lack of 
manpower and interest for an app thats a niche with a few thousand 
machines/users. More if you count the machines each user has, 4 for me 
and I'm just a hobbiest. But its the goto software when folks get tired 
of mach, or the proprietary stuff dies and the vendor has disappeared 
but the machine is still mechanically good, so it controls get 
converted. And often surprises the people with how much faster the 
machine is. It (we think) is whats makeing the Toyota

Kernels are among the safest packages you can bring in from a foreign
release.  They have almost no dependencies at all.  Just a magic hamster
that makes the system go.

Of course, you're still on your own if the hamster falls out of the cage.

I realize that Greg, but debian's support for armhf for unusual 
applications that require a realtime environment, is at its finest, an 
afterthought and discarded. We linuxcnc runners are used to it.  So we 
build our own kernels and pin them.

And so far, jessies apt has not issued a complaint other than advising me 
when a kernel update has been skipped.

Stretch on armhf, or arm64 (pine64/rock64) from the pine sites offerings 
is a disaster with sub 24 hour uptimes, so I am stuck on jessie, whose 
uptimes running this particular machine are from power bump to power 
bump. With a battery backup, which it doesn't have, uptimes would be 
essentially for the life of the battery. A superCap might even do it as 
I have a 20 kw auto starting standby here, power outages are about 5 
seconds.

Funny part is that I have built, on the rock64 using its own arm64 
compiler tools, one of the latest linux-rt kernels from that linux-rt 
mailing list, on the rock64, takes around an hour, but I can't get the 
pine people to tell me how to install it. I'd give you its version, but 
the rock64 is currently not online. Its running I think, but no one is 
logged in from its own keyboard. Some security minded person, in his 
infinite wisdom, has decreed that the networking will not be started 
until a user is logged in from its own keyboard. But howinhell can an 
ssh login be done over the cable when the networking has to be started 
by that same user which starts x too, me, going out and convincing the 
monitor to stay on the rocks cable long enough so I can login from its 
own keyboard. Classic chicken v egg no one gave any consideration to.  

How do I fix that for starters?

Know what you're doing :-)

In general, pinning is a way to have packages from a later distro
without getting everything upgraded.

That said, if you pull in anything which wants a newer libc,
for example, you're going to have fun :-)

Pulling in some new kernels. as Gene is doing looks (more or
less) harmless... as long as the libc plays along.

In general, I'd say: if you are running stable, pinning is
almost always a bad idea. If you are running testing, there
are more reasons for it.

But be prepared to second-guess your installer and to understand
why it wants to take decisions the way it wants.

FWIW, I've been running a Frankendebian (testing/unstable) for well
over two years. It's OK, but, just for one example, I couldn't run
aptitude, because its dependency resolver became hopelessly confused
and always wanted to deinstall half of my system (apt was mostly
fine, though). Be prepared to deal with such things.

Two references to skim (a bit oldish, but AFAIK still relevant):

  This one has examples for pinning:

Indiscriminate pinning is terrible. That's because it's a
powerful tool. 1001 is almost certainly not what you really
want to do here if you are regularly updating your system. And
if you are not updating your system at all, you don't need 
to apt-pin.

Here's a quick guide that I wrote some time ago:

---

Let us suppose that you are running Debian stable, but there are
some packages that you would like from the backports archive.
However, you don’t want all backports replacements to be brought
in.

In etc/apt/sources.list.d/backposts.list add the backports repo.
As I write this, Jessie is stable, so:

deb http://http.debian.net/debian jessie-backports main contrib
non-free

Note that the source lists must end with .list or they will be
ignored.

In etc/apt/preferences.d/priorities:

Package: *
Pin: release a=jessie
Pin-Priority: 900

Package: *
Pin: release a=jessie-backports
Pin-Priority: 50

and run apt-get update

There are magic levels for the numbers in the priority field.
They are explained, at length, in man apt_preferences. The
highlights:

P >= 1000 causes a version to be installed even if this
constitutes a downgrade of the package

990 <= P < 1000 causes a version to be installed even if it
does not come from the target release, unless the installed
version is more recent

500 <= P < 990 causes a version to be installed unless there
is a version available belonging to the target release or the
installed version is more recent

100 <= P < 500 causes a version to be installed unless there
is a version available belonging to some other distribution or
the installed version is more recent

0 < P < 100 causes a version to be installed only if there
is no installed version of the package

P < 0 prevents the version from being installed

Now, to install a single backported package, apt-get install
packagename/jessie-backports, and to install a backported
package plus any dependencies which are also backported, use
apt-get -t jessie-backports packagename

If jessie gets an update more recent than the backports version
you installed, it will be installed.

When you upgrade to the next stable version, remove the pinning
before the dist-upgrade, and consider if you need to reinstate
it.

For backports, the 
say:

  All backports are deactivated by default (i.e. the packages are pinned
  to 100 by using ButAutomaticUpgrades: yes in the Release files.

Beyond that, pinning is strongly discouraged in the IRC channel.  The
channel's bot says:

  Bugs are explained at
  
https://web.archive.org/web/20121017070250/http://carlo17.home.xs4all.nl/howto/debian.html#errata

I don't know why the page was removed, forcing the archive retrieval.
But there you have it.

Usually a user's attempt to do pinning is one of the steps leading to
what we call a "frankendebian" system, which is completely broken and
unfixable.  Hence, the strong discouragement against using it.

Hijacking a thread here, but it reads like I might be reading an expert.

"Pinning" is an interesting subject Roberto, interesting because the info 
on how to do it is generally skipped over, or only mentioned in passing, 
with NO examples of how to do it in the man pages available. I have it 
working on one machine, but it was a heck of a trip getting there, and I 
still have had no confirmation that I actually did it correctly. That 
machine is a raspi-3b running jessie. But with an rt-preempt kernel 
because its main reason-de-terre is LinuxCNC.  Its running a 3/4 ton 
metal working lathe.

In /etc/apt/preferences.d/kernel.pref:
pi@picnc:/etc/apt/preferences.d $ cat kernel.pref
Package:linux-kernel
pin: version 4.4.4-rt9-v7+
Pin-Priority: 1001

Package: linux-headers
Pin: version 4.4.4-rt9-v7+
Pin-Priority: 1001

Package: raspberrypi-bootloader
Pin: version 1.20170427-1
Pin-Priority: 1001

Package: raspberrypi-kernel
Pin: version 1.20170427-1
Pin-Priority: 1001

Is this the approved method? All I know is that for me, its working, and 
anything related to a kernel update is skipped.

Thanks for any further insight.

Neither of the package front-ends that I have used (apt-get and
aptitude) do what you describe. In fact, on every system I have upgraded
I end up with a section called 'Obsolete and Locally Created Packages'
visible in aptitude. In the case of an upgrade, that section has
packages that are installed on the system but which no longer have an
available candidate from any of the available sources. Removal of a
package as part of a dist-upgrade only happens if its dependencies can
no longer be met.

Re: Error while upgrading from Wheezy to Stretch

[David Parker]

I never thought to use the backports repo in Jessie to keep pacemaker
installed.  That's a great idea, I'll give it a try and see what happens.

Regarding Pacemaker's data and config, as far as I could tell, it was
gone.  I'm not positive what happened with it, but I wonder if the fact
that the pacemaker package was missing entirely from the new release caused
apt to just get rid of it during the upgrade.  I can also re-try that and
keep closer track of what gets removed.  I do know that when I upgraded
from Wheezy to Jessie and then to Stretch, and then I re-installed
Pacemaker in Stretch, it didn't find any old config data and acted like a
new installation.

Thanks!

I totally forgot about backports. Generally, including backports
repositories of the upgrade target (i.e., the suite being upgraded to)
is not a good idea. However, this situation would qualify as extenuating
circumstances. Plus, someone who manages a HA cluster almost certainly
has the skills to deal with the occasional minor hiccup assocaited with
mixing backports into an upgrade.

The only thing I would say is use apt "pinning" to prioritize the
backports repository lower than the other repositories so you don't

I'm still stumped by the claim that the configuration is being removed
during the wheezy->jessie upgrade.  Removing a pacakge during an
upgrade SHOULD NOT remove the configuration (i.e. it should be a
"remove" rather than a "purge").

So, the "obvious" answer would seem to be "upgrade to jessie, then
upgrade to stretch, then reinstall the pacemaker package, and it should
still see the old configs".  Of course this is assuming the old
configs are compatible with the new version of the package.  I know
absolutely nothing about this specific package.

According to http://packages.debian.org/pacemaker there is also a
backport of the stretch version of the package in the jessie-backports
repository.  So perhaps there is some way to convince the jessie upgrade
to use the jessie-backports version of this package rather than removing
it.  But that's beyond my experience.

Ah, but it is in jessie-backports [1]. I'd try to include those in your
jessie sources.list, perhaps that works out cleanly.

It is likely that you would have received different, and perhaps more
constructive responses, had you included this detail in the initial
description. However, that is in the past.

That said, it should be possible to upgrade without pacemaker and other
packages which are important to you being removed. The only thing that
would *force* the removal would be if one the dependencies was no longer
satisified. None of the first-order dependencies of any of the pacemaker
packages have versions specified with < (i.e., a maximum version on the
dependency), so in general I would say that what you are describing is
unexpected. Of course, there are lots of dependencies and those
dependencies all have dependencies of their own. It is certainly
possible that somewhere further on down the chain a dependency is
getting marked for removal it is filtering up and causing the removal of
pacemaker.

So, some strategies that might enable you to get a wheezy -> jessie ->
stretch upgrade to work include:

 - remove pacemaker first (note: 'remove' and 'purge' have different
   meanings when it comes to apt, with 'remove' removing a package's
   executables and other static resources but preserving configurations
   and user-generated content, while 'purge' will also remove
   configuration files and user-generated content), proceed with
   upgrades, and re-install after the upgrades are complete
 - start the upgrade to jessie and get far enough along to identify the
   culprit(s) of the removal, then manually remove those with 'dpkg'
   using the '--no-force-depends' option; that will allow pacemaker to
   remain installed, though in a broken state, while the offending
   dependencies are removed, after which you can proceed with the
   upgrade and when you get to the jessie -> stretch step the new
   pacemaker should get pulled in and the new dependencies with it
   (note: this approach may require a fair amount of manual intervention
   at each step of the upgrade process)
 - backup your pacemaker configurations and user-generated files, let
   the upgrade process remove the packages, then restore everything
   after the upgrade is complete

Re: Error while upgrading from Wheezy to Stretch

[David Parker]

Hi all,

Sorry I didn't get back to this sooner, had some crazy life stuff getting
in the way.

I should have said in my original post that there is a reason I'm trying to
jump from Wheezy to Stretch.  These boxes are in an HA cluster with
Pacemaker, Corosync, and DRBD.  I have all 3 of these installed from the
Debian packages.  Pacemaker is not in Jessie (apparently the devs missed
the deadline for inclusion), so an upgrade to Jessie uninstalls pacemaker
and all of its configuration.  That's what I was hoping to avoid, because
setting up an configuring Pacemaker always takes me a while to get right,
so an upgrade path which does not include the removal of it is preferable.

I did read the documentation and I did try Wheezy -> Jessie - > Stretch
first, but the problem was that Pacemaker was removed.  Hence, I was hoping
to skip Jessie.

If it's simply not possible to do this upgrade then I guess that's that.
I'll have to reinstall and reconfigure Pacemaker, which hopefully will
continue to be delivered in future releases without fail.

Thanks,
Dave

That's the short answer.

dpkg --configure -a   and   apt-get -f install   can be useful
to fix a logjam, but when you get an error like
 E: Sub-process /usr/bin/dpkg returned an error code (1)
it's worth running dpkg directly, seeing which packages are stuck,
and then try   dpkg -i 
as this can sometimes fix circular and reciprocal dependencies
that running from apt* is unable to solve.

BTW if they're test boxes, keep on trying: you may learn something
useful about rescuing systems, which the reinstall people won't.

Cheers,
David.

  given they are test boxes you should go straight

  much much faster than trying to fiddle around with
upgrades.  especially when many versions in between.

  of course, always check installation notes for 
errata and look to see if there are a lot of issues
reported for your specific hardware.

I would start by reinstating jessie in all of your sources
files, then try dpkg --configure -a, then apt-get -f install,
then apt-get dist-upgrade to jessie. After a successful jessie
reboot, upgrade to stretch.

The other "incantation" that's worth trying is

# dpkg --configure -a

Yes.  Retore both Wheezy systems from their respective back ups Then
read and follow the upgarde instructions which you should have done
first. And DON'T skip upgrading to interim releases to save time
thinking it's not necessary.  That piece of advice is in the
iinstructions, too, along with a lot of other wisdom to make your
upgrade as unproblematical as possible.

it is definitely less effort to upgrade to jessie and then to stretch - it
just takes a bit more time, but less effort in debugging.

can you reinstall or configure bsdmainutils?
or purge man and bsdmainutils and add them later if needed
