If coyote is really an alias and not part of domain name give us
grep -i coyote /etc/hosts

For what you show bpi54 is the short hostname so you need to do
ping -c1 bpi54
and not
ping -c1 coyote

I'd forgotten about that angle. IIRC, snaps are controlled by
Canonical. Flathub controls flatpaks. Appimages can be built by anyone,
but they are one file with *everything* in them.

I trust Debian to audit and ensure my packages are secure and
interoperable. I don't necessarily trust Canonical or Flathub.

I'm not a friend of flatpaks and similar concepts, either. For me,
it's not memory use, but the shifting of power from a distrubution
model to single applications. I find that makes software less "free".

In a distro, applications have to get along with each other, agree
on a common set of libraries, file system layout, etc. I think this
is a Good Thing. Every app carrying its own little distro is like

I principally wanted to confirm my suspicions about memory usage.
There's been increasing usage of Flatpaks, Snaps and Appimages. As
though it's a solution to the "problem" of distributions' own package
management systems. And now Fedora is openly embracing Flatpaks.

I find the trend disturbing. If you have a lot of apps running, and
they're all these types of packages, you're going to be using
considerably more memory. The alarming increase in the size of the
Linux kernel is yet another symptom of this idea that, because memory
is cheap, we simply use more. In my mind, it's a little like having
access to unlimited amounts of water and thus using all of it you can.
Or gasoline/petrol. Or food.

I don't have a problem with Debian's packaging system, and am generally
satisfied with the stable but older versions of Debian packages. They
get the job done.

Maybe I'm weird.

Flatpak is the odd one out and doesn't exactly work like this. Rather
than completely self-contained images, the packages aren't that much
different from what we have in Debian. The difference being that as for
dependencies it's more of an all or nothing affair. Or what's called a
"runtime", basically a small userland mostly tied to specific desktop
environments. Clearly not as economical, especially if all you need is
a single app, which to be fair isn't Flatpak's intented use case, or
everything you're using needs a different runtime. It's also simpler
though. With nothing but, say, GTK software you might always get away
with a single runtime. I do, although with very few apps installed.
Yes, if you're then also running something installed via Debian, or yet
another package manager, with the same dependencies, there's
redundancy, this is true even where versions match. I wouldn't rack my
brains on that however, modern loaders are quite intelligent and
dynamic linking is selective in a sense. I guess it's quite attractive
for people like me who are not even using one of the full-blown DEs
like GNOME, so there's little that must be resident all the time and
I'm more flexibel in "load balancing" if need be, which should be
almost never considering today's memory supplies. And I don't think any
of these solutions is specifically catering to resource-constrained
systems. With that you're probably always better off with installing
from a single source.

I was attracted by this idea and it gave me pause for

The specs require IPP (put in firmware, I suppose) and
DNS-SD discovery (again in firmware). Little extra cost?
AFAICT, a networking stack is not specified. Why should
it be for an isolated machine?


Because that's how IPP works: IPP-over-USB essentially creates a 
point-to-point network to the printer, which is then addressed via TCP 
just like any other networked printer. Historically there was a 
significant cost associated with adding a networking stack (more

essentially a zero-cost addition. It's not going to be added to old

Disabling the start of the avahi-daemon did not change the situation.
Deinstall of avahi-daemon did not help, too.

Yes, and that's a problem for anyone trying to replicate the

Alright guys, I may have an existing system here that shows a 169, but 
not as default. Running Armbian bullseye AND xfce4, in fact I have 2 of 
them that show an ip r of:


gene@bpi54:~$ ip r

default via 192.168.71.1 dev eth0 proto static metric 100
169.254.0.0/16 dev eth0 scope link metric 1000
192.168.71.0/24 dev eth0 proto kernel scope link src 192.168.71.12 
metric 100


Probably have 4 of them, but only two are powered ATM, and the other is 
busy running klipper and a 3d printer.
And networking is running fine on all 4 despite its being present as it 
is not the default. And all are using xfce4, because the gnome screen 
blanker is an instant crash and burn, requiring a power down reset to 
recover from. The xfce4 blanker Just Works.


The reason you've never seen any logs etc is that if its the default. 
there is no way in hell to get you those logs or other info because 
there is no network to get it to you.  We could take screen pix, but my 
camera makes 5 meg jpegs the server won't take.


So maybe we can figure out whats different about Armbian that makes it 
work. Give me some troubleshooting commands to see if we can figure out 
whats different about armbian that makes it work when there's no way in 
hell to make it work with a debian install of bullseye and going clear 
back at least to stretch, maybe further? Except nuking avahi and rebooting.


Maybe this is your chance to come up with a fix that doesn't get us a

Did you ever open its manual? Brother ships a plastic bag with such things as
driver disc, manual, warranty registration card and such with its printers.
Generally these things have a copyright date on or in them somewhere. From the
paper manuals from my two most recent Brother acquisitions:

MFC-J480DW - © 2015
MFC-8910DW - © 2012

The one for my HL-5470DW is more effectively squirreled since I moved. Its pdf
manual has no date near its front or back that I could spot, but the timestamp 
on
it is 122 months ago, same as a freshly downloaded copy.

Irrespective of the lines that interested Brian, how did your system
manage to produce no output, whereas Greg's and all of my systems
produce lots; in my case, 95, 141, 226, 278 and 303 lines.
(Greg used sudo, whereas I logged in as root.)

The extra sections that root reports appear to be variously:
  Hub Descriptor:
Hub Port Status:
  Binary Object Store Descriptor:
  Device Qualifier (for other device speed):

Yes, and that's a problem for anyone trying to replicate the
configuration of these addresses: we usually never see files
and logs from offending systems, but just reports of package
deletion or, even less helpful, so-called nuking of random files.

IPP-over-USB basically requires the whole traditional networking stack,
so it's no surprise that it's usually present in printers that include
a network interface (very little extra cost) and not in
USB-only printers.

So... yeah, I guess we're saying that your printer was 5 years old at the
moment you bought it.  Or at least, that it was a 5-year-old *design*,
even if that particular printer had been assembled more recently.


The Brother HL-L2320D seems to have come on the market in early
2016. I haven't any idea when Staples decided to stock it.


Now, personally I don't consider a 7-year-old product to be an antique,

I do not consider a 7-year-old product to be an antique. The
significance of 2016 is that it is four years after the
IPP-over-USB standard was ratified.

Network printers from 2016 almost certainly (always in my
experience) do ship with IPP-over-USB. For some reason USB-only
devices generally do not provide it; it's very hit-and-miss.

I do not know why all vendors (not just Brother) have taken that
decision. It's a real pain as it effectively makes the printer
a legacy model and very much limits how it fits into the Debian
printing ecosystem.

The big scanner/printer has an ip address, but its a lot slower when 
using ipv4 to operate it, I wiresharked it back about jessie, and found 
why, the cups driver for IPP was sending a bad crc the first 6 times it 
tried to wake it up before it decided to send a good crc, so there was a 
1 minute time killer just to wake it up. Then it was about a 5 kilobaud 
circuit, about a minute a text page. Its at least 5x faster on a usb2 
circuit. A ping works in 0.5 milliseconds, but that doesn't wake it up. 
Its much faster on a usb circuit.


I made some noise about it at the time, but was ignored. I don't know if 
dfu could update its firmware, or if its too old for that.

I finally gave xi2bind a try, using the hierarchy option to do something
(run xmodmap) when a keyboard is plugged in. Or in my case, I have a USB
switch which connects or disconnects a USB hub with my mouse and
keyboard connected to the hub.

It works fine but usage was a little baffling and it doesn't help the
example on how to use the hierarchy command doesn't work due to wrong
quoting.

With some work I think I've worked out which event when the keyboard is
plugged in I should use to run xmodmap, out of the six that happen when
my keyboard is plugged in. With the mouse and hub the total number of
events is actually 16!

For sure it doesn't really matter if xmodmap runs sixteen or six times
or only once but it feels right.

So for adding my extra keys to my quite normal US layout keyboard this
works fine. Unfortunately something weird happens with the modifier keys
and my extra keys working depend on setting Alt_R to mode_switch and
that's not something I can automate currently. Nothing to do with
xi2bind though.

I do not believe that to be the case.

As your user run 'lsusb -v | less' and clear the screen

Heskett did use sudo. Note the different messages.

Anyway, this USB-only printer from 2016 does not provide
an IPP-over-USB service. This is not unexpected.

Are you saying that this printer has been sitting on the Staples display 
for 5 years when I bought it new about when it first showed up there 2 
years ago? And I bought it to  replace an older but nearly like model 
that had decided it did not have a toner insert when it had a new one of 
the proper ID in it and had been using it for a couple reams of paper 
already?


I find it quite unlikely this printer is 7 yeas old. My bigger, tabloid 
sized printer, yes, easily 7 years old as I originally bought it to do 
rockhopper printouts of the control logic of my linuxcnc machines with 
fewer sheets of tabloid sized paper. A single machine can output enough 
logic info to piece together, taping sheets together to cover a wall, 
more than covering a single 4x8 foot sheet of plywood. Great for 
troubleshooting but eats shop space like M's candy.

Este es justamente el caso. Sumar varios almacenamientos web, por ej
Google Drive + Mega, o dos Google Drive.

I do not believe that to be the case.

As your user run 'lsusb -v | less' and clear the screen
(CTRL-L) or scroll up and down. Observations? Gene
Heskett did use sudo. Note the different messages.

Anyway, this USB-only printer from 2016 does not provide
an IPP-over-USB service. This is not unexpected.

Ben en fait je crois que le problème est que tu n'es pas dans la bonne 
discussion, là le hors-sujet c'est "quel espace laisser à Windows".

Pour ton sujet "Davinci resolv ?" je t'ai déjà répondu que ce n'est pas un 
logiciel libre donc le source n'est pas disponible donc il n'y a rien a 
compiler.

C'est un script bash donc ça ne se compile pas. Il permet de lancer
la version linux de davinci resolve prévue pour centos dans un conteneur centos 
sur un système ubuntu.

Sauf que c'était un [hors-]sujet sur Windows...

Voici la réponse de Chat-GPT :

Je suis désolé, mais je ne comprends pas votre message. Il semble contenir 
plusieurs phrases disjointes et sans contexte clair. Si vous pouvez préciser 
votre question ou votre préoccupation, je serais heureux de vous aider.

Re: Debian 10 planté par mise à jour pour autre version (+ récente)

[Sébastien NOBILI]

Bonjour,

Le 2023-02-13 17:39, Romain P. a écrit :

La commande " dpkg -l | awk  '/libc-bin/ {print $2,$3}'" renvoie
"libc-bin 2.28-10+deb10u2".

Les 3 commandes contenant "apt" renvoient
"GLIBC_2.34" et "GLIBC_2.35" "not found".


Le système a donc toujours une libc (bonne nouvelle) mais la version 
n'est pas

celle attendue par apt.

La commande commençant par "wget" indique que le téléchargement a été 
effectué.


Y aurait-il autre chose a effectuer ?


Au point où tu en es, ton système est dans un état non-prévu. Ça se 
répare mais
c'est complexe, ce sera long et il faudra sûrement forcer un peu. Ça 
peut fonctionner

(ça m'est déjà arrivé plusieurs fois) et ça sera très enrichissant.

Tu n'auras pas la garantie d'avoir retrouvé un système complètement 
intègre.


As-tu le temps et l'envie de te lancer dedans ?

Si la réponse est non, alors sauvegarde ce qui t'est cher et réinstalle.

Si la réponse est oui, alors sauvegarde ce qui t'est cher et (au choix) 
:


- installe le .deb de la libc que tu as téléchargé (via la commande 
wget)

  avec la commande suivante :
   dpkg -i libc-bin_2.36-8_amd64.deb
- télécharge apt/stable et installe-le avec dpkg :
   wget 
http://ftp.fr.debian.org/debian/pool/main/a/apt/apt_2.2.4_amd64.deb

   dpkg -i apt_2.2.4_amd64.deb

Ça risque de commencer à coincer dès cette étape, il faudra analyser 
pourquoi et insister.


Ensuite il faudra faire le downgrade du système.
