Hello


I use gmail, and seem to be getting email from this list. I wonder if it

I think you are on to something: It could well be that there has been a shift
to using how the recipients organise their gmail (do you sort it into
a high value folder, do you reply to it, do you star it, etc, etc) as
a factor in the decision to reject email at the SMTP transaction.

That might explain why a small subset of gmail users still get to
see the DNG messages ... if the heuristics are local to a user.
Which seems reasonable, otherwise a spammer could sign up and superlike
the their own spam, guaranteeing delivery for others too...

Though I am not sure I should expend the energy to run some tomography on
these interactions, in order to discover the heuristics that
google actually uses - with apologies to the hitch-hikers guide to
the galaxy: As soon as we have an explanation, the system will be
replaced by an even more complex set of rules.

What it does seem to mean is that gmail users are likely
missing some legitimate messages completely - without even a
trace in their spam folders.

I suppose that is just another instance of the Availability vs
Integrity vs Confidentiality Tradeoff that underlies most
of Computer Security... though I for one like to make that
call myself rather than having some AI try infer that from
my mail reading behaviour.

marc


Not for to use this list but i do have a gmail account as spamcatcher 
for a publicly visible mail address. I never use the web interface 
though but use Thunderbird to handle that account. So i do not see fancy 
lines or high value folders or am using stars. So far Google does handle 
spam correctly and I do not have to search that often in the spam 
folder. I recommend this for all gmail users.


I do run my own MTA (three of them actually) and noticed a rejection by 
gmail the moment I got IPv6 and forgot to set reverse DNS for it. So 
rDNS is a thing for gettingaccepted by gmail.

Hello,

I've been running Devuan on my break even public facing webhosting 
system for several years.  I've been using ISPConfig and the debian 
perfect server instructions with adjustments for Devuan. I'm up to 
Devuan Beowulf at the moment and trying to go to chimaera so that I 
can get PHP 7.4 support.  I'm happy to build a new server and migrate 
sites from Beowulf to Chimaera except that PHP 7.4 goes end of life at 
the end of November of this year.  The current versions PHP are 8.0 
and 8.1.


Using the instructions at packages.sury.org, I am able to add the 
other versions of PHP except for PHPN.n-fpm due to a (what seems to be 
a completely unnecessary) dependence upon systemd.


I would love to keep running Devuan.  It runs way better than anything 
systemd based.  Is there a workaround for this limitation?  I've tried 
installing the package from chimaera, but it's a couple of minor 
revisions behind sury.org. It also seems to need a version of libc6 
greater than or equal to x.xx.


As a web hoster I need to be able to deploy multiple versions of PHP 
and I don't see very advanced support for it in Devuan. Developers 
need to test PHP 8 as it's different enough to cause trouble for apps 
written intending to run on version 7.4



Trying not to install ubuntu,

I am running PHP in docker containers for the purpose of running

docker does not work for you can look for the PHP start command in the 
docker container which does not have systemd dependencies afaik.

You shouldn't do that. Although its possible to "partition" SD-Cards,
this is not recommended. This is since SD-Cards have some kind of
knowledge about "how FATFS works" to optimize the write cycles. This
won't work if the card is partitioned.

Bit wierd that X-gazillion Raspberry Pi's out there are expected to work
with partitioned SD cards.

There is a reason that SD-Cards wear out quickly with a Raspberry Pi. 
But the Pi need to boot from a FAT partition and at the same time 
Raspbian will not run on a FAT partition. Luckily you can boot them from 
the network and from USB pen drive or SSD too.

Thanks Nick,

Yes, I saw your response back in 2020.

I've been trying to figure out how that applies to network manager, or how I

The problem here is network-manager gets killed early in the process. Same 
result but a different cause.

Hi Brad,

I already thought to have seen the question before. Too bad it does not 
work for you.


But maybe I have another solution. I am using chrony and this uses a 
small script in /etc/NetworkManager/dispatcher.d named 20-chrony and 
this content;



#!/bin/sh
# This is a NetworkManager dispatcher / networkd-dispatcher script for
# chronyd to set its NTP sources online or offline when a network 
interface

# is configured or removed

export LC_ALL=C

# For NetworkManager consider only up/down events
[ $# -ge 2 ] && [ "$2" != "up" ] && [ "$2" != "down" ] && exit 0

# Note: for networkd-dispatcher routable.d ~= on and off.d ~= off

chronyc onoffline > /dev/null 2>&1

exit 0


So maybe you can make a small nfs shutdown script and put it in 
/etc/NetworkManager/dispatcher.d too or make a link to 
/etc/init.d/umountnfs.sh?


Grtz.

It accepted the baud rate option this time however the middle button

This way you reacquire a fresh ip from the DHCP server.||

of eMMC flash, Gigabit Ethernet, 2 x DisplayPort, 4 x USB and audio.


I have set the BIOS back to defaults, booted from the server 
installation on a USB stick made with Rufus 3.17 and performed the 
installation, re-partitioned the eMMC flash, installed minimum 
components and the installation has run to the end successfully and 
for the "Now time to boot to your new installation".


When rebooting the machine it drops to a "No bootable devices" error.

Now these systems are EFI based and do not appear to have any legacy 
drive support in BIOS.


I have run the installation a second time and paid more attention, 
when it installs Grub it doesn't pop a menu asking where I want the 
boot loader installed (MBR, first partition,) or providing a list of 
'drives' or block devices to choose where to put the boot loader - 
instead something flashes past about grub and EFI and it completes, 
but after cycling the power the system isn't bootable.


Is there something incomplete/configurable/different that has to be 
done on systems with eMMC/EFI to get them to boot?



Mike



IIRC there are two common problems. 1) On the EFI partition there is a 
hard link to Debian directory which should be Devuan or reverse 2) The 
BIOS is expecting a bootx32.efi whereas only a bootx64.efi has been 
installed


You can check this with the tools from the link to GrubEFIReinstall from 
Tim Wallace mail.

Hi all,

https://www.youtube.com/watch?v=ECCr_KFl41E

Thanks for the link to that - brilliant talk. I've always thought
that Brian Kernighan himself was the great communicator in the
UNIX group - I wonder whether "The C Programming Language" and
"The Unix Programming Environment" would have happened without
his obvious ability to take abstruse and difficult material and
make it accessible.

If I had one incredibly tiny nit to pick, it would be that he
didn't mention GNU (it appeared once in the slide showing Linus'
original email). Without GNU, it's reasonable to suppose that
linux wouldn't have happened.

I disagree with "it's reasonable to suppose that".

Linus Torvalds was building a system for himself, partly (I
believe) because he liked Unix but couldn't afford a Unix system of
his own, and therefore he was of course going to build it using as
much free (of charge) software as he could.

That meant GNU.

I think the Unix philosophy and design principles are beautiful,
and formed the basis of an amazingly efficient system, but some of
those principles are embodied in Linux and some are embodied in GNU
(for example, devices as files, and pipes, in the first; and tools
such as tr, cut, grep in the second), so these days we can't really
separate the two - Linux is nothing without GNU (although the
reverse is not true).

And don't forget Minix, the system he used while developing his
kernel.

Didn't Linus start what became Linux because Minix was only 286 capable
and was not going to be upgraded and Linux wanted something that
would run on 386 cpus.

I think there was also a licensing issue involved in modifying Minix.

As far as I know, minix came from Andrew Tannenbaum at the Free University
of Amsterdam.and maybe also from the students in an OS course.

I don't know the details, but it was at one point sold commercially, although 
its main purpose was for teaching.

Whatever the licence then, it seems to have ended up with a sufficiently
free licence for Intel to put a copy of it in the management engine in
their CPUs for the last decade or so *without informing Tannenbaum*.
Tannenbaum was miffed; he said the licence allowed this, but he would
have liked to have been informed.

I still do have the book and floppy disk from the 1.0 version somewhere 
in storage. At the time it had a restrictive license and I had Sun and 
HP systems to play with at work so I have not done much with Minix . 
Later on I moved to Linux and forgot about Minix until I learned that 
Intel implemented Minix in their processors ME which was a big surprise 
(Indeed even for Tannenbaum!).

Hi Mark,

Thanks for the tip. I remember using debootstrap a long time ago and
it wasn't exactly fun, or trivial. I am looking at Howtos and It does
sound like an awful lot of work just to build a LV2 audio plugin from
source.

Just to clarify again, the plugin I am building is only distributed as
source code, no binaries provided and no distro packages of any kind.
I don't need a .deb package of this software, just the output
binaries, nor I intend to make one.

Here's the software if anyone fancies a play:

https://github.com/brummer10/Fluida.lv2



Dependency

libcairo2-dev
libx11-dev
lv2-dev
libfluidsynth-dev


For now I've hacked it by force installing iibsystemd-dev and
libfluidsynth-dev, building the plugin, and then uninstalling them. I
wonder if it could be easier to just spin a vanilla Debian system in a
VM next time.

The other alternative I can think of would be to just install the libs
from source and comment out the systemd bits. Upgrading sounds painful
though.

Cheers,

I can give it a try building it in a Debian docker container with all

That would be easier then a complete VM for a few dependencies.

Greetings

In anticipation of a fiber optical connection (moving from a wireless) I
have been planning out and purchasing some bits of hardware. Am finding
that networking is, at least sure seems to be, another black hole 
for time

and effort.

TL;DR (skip to last paragraphs for the question(s))

At present this is a soho office kind of installation but that will 
slowly

be morphing into something that is at least somewhat larger. There are a
number of input sensor locations being worked on some of which would be
generating, initially at least, up to 15 data streams sampled possibly
every second (some maybe more often - - - decisions aren't all done 
as yet)
so there will be a fair amount of data running around on my network 
which

I'm trying to keep largely a wired affair.

At this point I'm working on the three entry bits of hardware (and their
software) - - - the router, hardware firewall, and the managed 
switch. The

initial hockup on the fiber system is going to be at 250 Mbps sysmetric.

For the router I'm planning on using OpenWRT running on a Nanopi r4s 
which
according to the folks over on openwrt capable of even very close to 
full
Gbps speeds (IIRC tested to some 918 Mbps) which would give some 
headroom

for future increases although I don't see a need for the foreseeable
future.

For the switch I have found myself a XyZel 1900-48 that I'm working on
getting OpenWRT on. This ability to run a managed switch on OpenWRT is
somewhat new but its open source and I'm not tied (I don't think) to
OpenWRT - - - - except I don't know any other real alternative - - - so
that's not a difficult solution either. I don't 'need' 48 ports but 
I have
16 at present on a hub and its almost full and that's for stuff only 
here

in the orifice (sic!). I also want the capabilities of forcing streaming
services and wireless communications to not collect any more data 
from any

other part of the network (using VLANs) as is possible.

Then lastly to the hardware firewall.
I've been looking at pfsense and opnsense. Both are ipv6 possible 
although
both are mostly focused on ipv4 at the present. IPfire seems to have 
gotten

itself into a holding pattern and is not continuing work toward ipv6
functionality. Any one of these options are producing headaches when I'm
trying to figure out how to configure them - - - nothing installed at
present, just researching so far.

So - - - - questions - - - -
1. is my splitting the network system into the three parts a good 
idea or
should I truncate parts 1 and 2 into the router? If you would please 
give

reasons - - - please?


Hi,

If you want to have reliability splitting is good, if the router breaks
you still have a working firewall and switch and so on.
If you want also some redundancy you should think of buying
two of everything:

2 routers
2 firewalls
2 switches (2 x24 rather than 1x48 ports)

I personally prefer x86 hardware for this kind of things
when I see that little boxes like the Nanopi R4S they make me
think about toys. In my case sadly I'm tied to adsl over pots
so for the modem I still need to use this little plastic blackboxes.
In your case I would swap the nanopi for a nice mini-itx board
with intel nics, a sfx/flex psu (or pico psu), 4-8 gb of ram and a well
ventilated case (with low noise Noctua fans).


2. are there any good sources for information on and about networking?
debian has moved to nftables from iptables  - - - is devuan doing
similar?


I think so.


Where does one find information to enable a firewall that works yet
isn't stupid?


I use arno-iptables-firewall It is easy to create a basic setup for 
your network,
reliable, comes with good defaults and can easily be tweaked (for 
port-forwarding,
vpns, geoip filtering and so on, don't know about vlans as don't use 
them yet).


(I've wondered about having some kind of easy 'switch' that when 
users left
their systems that the system wouldn't be calling home in the 
overnight at

least a la ms googly. Dunno if that's 'simple' or not - - - so much to

I’ve just finished setting up a new router using PCEngines APU2 
(apu4d4 model) with OpenWRT. Uses x64 AMD Embedded G series GX-412TC 
and has 4x Intel i211AT Ethernet ports. It also runs a Coreboot bios 
and I can see regular bios updates approximately monthly. The coreboot 
bios and AMD CPU were the main reasons I picked this over a Qotom box. 
It’s also fanless which is good for a quiet environment.


The only downside is having only serial console output so you need a 
serial cable or serial-usb cable for the initial setup or bios 
configuration changes. Thankfully subsequent bios updates can be done 
with OpenWRT via flashrom.

the source of the claim that big pharma spends more on marketing than on
research, before I repeat it, and am left without a defense.

Hi all

About one or two years ago I had installed Devuan on my brother's laptop.

It is a Lenovo B50-10 (model 80QR), with a 64bit Intel N3540 CPU, 4GB
DDR1600 RAM and a mechanical 500GB HDD (see:
https://pcsupport.lenovo.com/cr/en/products/laptops-and-netbooks/lenovo-b-series-laptops/b50-10/80qr/documentation/doc_userguide)

Two weeks ago I tryed some BIOS changes and did an apt-get update/upgrade.
Do not remember neither which BIOS changes I tried, nor the order I did
changeas and apt-get...

This resulted in a unbootable system (a loop, booting and rebootin,
without starting the system).

Ok... I know I was too hurried and not very careful...

I tried to fix the situation using some usb live tools, but without
success.

Anyway, as the previous installation had not been completely smooth, and
the system had been a little messed up by my brother, and I don't want to
waste more time trying to fix it, I'm about to reinstall it.

Very shortly, the plan is:

a) Set the BIOS in UEFI Mode (and not legacy: it seems that Lenovo
machines will only have this mode in the future)

b) Download and use the most updated Devuan 3.1 netinstall ISO from USB

c) Run the installation procedure -- About partitions: I think I will use
the partitioning tool (in manual and non-automatic mode) provided by the
ISO, possibly maintaining the same scheme of existing partitions

Kindly, I therefore ask you observations and advice about this plan.

My major doubts are about the HDD partitions (which is a 500GB
*mechanical* HDD), and how to be sure I will have a stable and clean boot
process.

Many thanks in advance

I wonder if you have been bitten by "grub-efi-amd64-signed bug: 
hardcoded link -> unbootable system" earlier on this mailinglist.


When you have a separate /home partition I would go for the manual 
partition route and leave this partition alone. After installing and 
stable boot you can add the home partition manually in /etc/fstab and 
have all your brothers settings back.

Just curious: what are you using a s6 inside docker containers for ?

I've always been under the impression that docker containers are meant
for running only one application/service per container and thus don't
need an extra service supervisor inside the container.


By the way: IMHO a huge portion of the whole topic is describing the
individual services. I've made some experiments on some hi-level
service description that hopefully should be universal enough for
driving quite any supervisor/service manager on any distro from that,
while still being easy to maintain, even for the actual package
upstreams. Of course, that's just a little PoC, nothing usable in
the field. https://github.com/metux/srvman



--mtx

I know the theory but in practice I wanted a small static server with 
Letsencrypt and cron enabled in one small container. So I took a Alpine 
base image added s6 and the services needed. BTW Alpine uses busybox 
crond not cron. Especially for small an low resource computers you will 
prefer 1 containter above 3  separate ones.

The Evergreen 'system' uses ejabberd as a communication tool and it
would seem to me (new at digging under the hood as it were) that
ejabberd is quite intertwined into this system.

Ejabberd was installed as part of the install but then  in the setup
it is necessary to shut it off.
The install workflow used 'systemctl' etc etc as a control
I used 'service ejabberd stop' which worked but when I wanted to
restart the service the complaints started.

Is there a simple way to change this reliance on systemd or is this
something better left to someone who does know what they're doing (not

Most likely you cannot do service ejabberd restart after a stop. You 
have to use service ejabberd start
Otherwise you get a error/warning that no running service has been found 
before starting the service.

Right.  For spacefm it is udevil.

This is one of the "gotchas" that can happen when running an "in

things.  Most of the time, it's because a dependency, like udevil to
spacefm, become mismatched version-wise.  That is, udevil has become
"too old" to work with spacefm, and the upgrade process uninstalls it.
Try "full-grade" instead of just "upgrade" to get the newer version of
the dependencies when "upgrading." In fact, this is the recommended
procedure when running an "in development" or testing version.


Please - - - not understanding the command(s) suggested.

# apt update

The right command is  apt full-upgrade.

The main difference between full-upgrade and upgrade is full-upgrade 
also delete dependencies which are no longer used. I guess that the 
older version apt-get dist-upgrade does do something similar.

   * Add smoke autopkgtest that can run in containers.
 Add a simple test of cockpit-bridge and the login page to ensure that
 packages have the right dependencies and contents, and that the systemd
 units are set up correctly to get a login page on
 https://localhost:9090.
 This can also run in a container and thus in Debian's CI and on all

it may cause us difficulties.

Maintaining such list is not feasible for one person. Personally I was
thinking of a wiki page with packages broken by systemd with version

I do have one stubborn laptop which has a similar behavior and to keep
it going i have entered the dns in /etc/resolv.conf and made the file
readonly. So far this works fine.

Most likely it does do a domain name lookup which times out by lack of a
ppp connection.

Edit: list.dyne.org was not added automatically.

I did not keep notes when I installed it but /dev/mmcblk0p1 has been
mounted as /boot. Booting from a Pi 2b depends on bootcode.bin, dtb's
and kernel being present on /dev/mmcblk0p1. If I remember correctly I
kept the whole install from a Raspbian sd-card and changed the
apt/sources.list first to ascii updated and after that to beowulf. And I
cloned and builded https://github.com/raspberrypi/userland for the
typical Raspberry Pi userland software.

I could not find the raspi-firmware package you mentioned. After adding
the non-free repo the raspi3-firmware was present which indeed contains
bootcode.bin etc. But apt tries to install this in /boot/firmware which
does not exist on my Pi. So maybe you need to copy the contents of
/usr/lib/raspi3-firmware/ manually to the mounted /boot directory. From
experimenting with booting from NFS I remember that bootcode.bin must be
present in the root of the first partition. Which after booting is
mounted under /boot

Remember this only works for Rpi 2 and higher. In the past I have been
bitten by updating a Pi 1b to Devuan Jessie because of the arm v7
instruction set being used in Devuan/Debian while Pi 1 and Zero are arm
v6 with hard float instructions.

For my regular Pi's i just have the following in my apt sources

deb http://deb.devuan.org/merged beowulf main
deb-src http://deb.devuan.org/merged beowulf main
deb http://deb.devuan.org/merged beowulf-security main

and this just works.

For my Pi 1's and Zero's i have to specify the armel architecture
because apparently Debian arm v6 does not exist.

Well, i do not live in the USA and chances of being fired or risking my
career for defending Stallman are not existent. So privately I most
likely will sign this open letter.

But I would like to keep politics *any politics except init freedom* as
far as possible from Devuan so I will not in any way connect my signing
to the Devuan project. And I suggest others to do the same.

In its current state (with little updated profiles working with enforce)
it does not add much to your daily use imo. According to
https://wiki.debian.org/AppArmor/HowToUse#Disable_AppArmor it is enabled
by default in Debian 10. And you can disable it with a kernel parameter
in grub.

Hi,

Mostly agree with you and in its current state apparmor belongs to this
list. In the same time I like the idea of apparmor in limiting apps
behavior. It could be most useful if implemented correctly.

Did you try

    zfs sharenfs=on tank


and

    showmount -e

or

    exportfs

and if both don't work

    zfs share -a

Hi Fred,

Any USB disk device should work. As a precaution you could use a USB2
port. You have to unzip the file to the USB device to let the BIOS find
the file with the new version. $120 is a lot of money hopefully you can
sell it after the upgrade.

Grtz.

You do not need Windows to update a BIOS on a Gigabyte mb but can use
Q-Flash from BIOS instead. Too bad you still need a working processor
and memory to make this work. Your motherboard does not support Q-Flash
Plus with which you even do not need a processor to update the BIOS.

Depending on your hardware and driver the easiest solution is to
blacklist the synaptics driver and modprobe it by hand whenever necessary.

Workarounds are great of course but I found that default eudev does not
compile with --enable-rule-generator anymore and that is likely the
reason this problem has appeared now.

It looks like systemd again is responsible for this mess. From what I
understand uses eudev the same files as systemd with udev. If so you
should do

ln -s /dev/null /etc/udev/rules.d/80-net-name-slot.rules

to make sure (e)udev does not mess with the network devices. (/etc/udev
seems to have priority above /lib/udev)

After that it is somewhat unclear to me. Or
/etc/udev/rules.d/70-persistent-net.rules should work again. Or you
should add a 70-net-name-slot.rules with the syntax of
80-net-name-slot.rules like

SUBSYSTEM!="net", GOTO="net_setup_link_end"
IMPORT{builtin}="path_id"
ACTION!="add", GOTO="net_setup_link_end"
IMPORT{builtin}="net_setup_link"

NAME=="eth0", ENV{ID_NET_NAME_ONBOARD}!="", NAME="$env{ID_NET_NAME_ONBOARD}"
NAME=="eth0", ENV{ID_NET_NAME_SLOT}!="", NAME="$env{ID_NET_NAME_SLOT}"
NAME=="eth0", ENV{ID_NET_NAME_PATH}!="", NAME="$env{ID_NET_NAME_PATH}"

LABEL="net_setup_link_end"


After adding net.ifnames=0 and biosdevname=0 your system should work as
intended but I do not have the time to test it, hopes it helps in the
right direction.

Are you sure that your exim4 mta has not been simply denied access by
Google because it has no static ip, spf, dkim etcetera? An alternative
would be to use your isp smtp-server by configuring it as a smarthost
like in this example

Coming from Debian you maybe should change your sources list first to

deb http://deb.devuan.org/merged jessie main

and install the devuan-keyring and sysvinit-core before you move over to
devuan ascii.

I do administer 3 different mailservers from which 1 does have the full
package from spf, dkim and dmarc. In my experience dmarc does not add
much of value but spf does. Dkim is much liked by isp's with strict spam
policies. But those are still reachable without after some waiting time
as long as you are not on a spam blocklist. A reverse dns record does
help too.

To ease the maintenance of those servers i intend to migrate them to
docker containers. I wonder people on this list have experience on this
subject?

I do not have experience with Zoom but with Jitsi and discovered that
disabling WebRTC leakage in Firefox because of WebRTC leaking ip
addresses also crippled Jitsi.

My ISP hand out static ip (4 and 6) and allows me to change rDNS too. So
i do run one of my mail servers from my home FTTH connection.

It also helps if you configure SPF and DKIM for your domain. Rejected
mails almost never happen, mostly only random by Microsoft O365 servers.

For those who ISP blocks port 25 you can configure your mailserver and
client to use port 465 (SSL) or 587 ((START)TLS) both with authentication.

In this thread it is mentioned that for use as a daemon you better user
the python-inotify module because just piping inotify does have
unexpected behavior like with runinit and s6.

Actually i would plugin kbd & screen before pushing that big red switch.
Once logged in scp or sftp the public key from yourworkstation and move on.

The first option disables the check of drives for the presence of
(other) filesystems. The second has indeed to do with partitions only
and you can ignore that one.

According to grub documentation you can make grub-mkconfig skip a drive
with one of these options in /etc/default/grub

'GRUB_DISABLE_OS_PROBER'
 Normally, 'grub-mkconfig' will try to use the external 'os-prober'
 program, if installed, to discover other operating systems
 installed on the same system and generate appropriate menu entries
 for them.  Set this option to 'true' to disable this.

Hi Edward,

By using apt instead of apt-get you get the question if you want to
accept the change. Answering yes will make apt or apt-get update work again.

From what i am able to find the kernel parameter:

    usb-storage.delay_use=

[UMS] The delay in seconds before a new device is scanned for Logical

g_mass_storage is used in usb otg mode where the system mimicks a usb
gadget. Most likely the usb_storage module is compiled in the kernel.

Which is still quiet high. I would advise to renew the thermal paste on
your processor. I can recommend Arctic Silver 5 AS5-3.5G Thermal Paste.
Made a difference of another 20°C on idle on my old i5.

I did have a similar problem with a Raspberry Pi caused by fsck taking
to long to end. If you can add a keyboard giving a CTL D it maybe continues.

Because i only do have data on it I entered a mount in rc.local.

But maybe if you fsck the drive on another system?

According Geekbench
https://browser.geekbench.com/v4/cpu/compare/12415873?baseline=12415673
removing mitigation mainly makes a difference on single core performance.

But i recently did see some Intel firmware update passing at my system.
So maybe Ascii has not yet received the same updates as Beowulf.

As seen earlier on this list you must use

apt update

instead of

apt-get update

Because apt will ask if you agree and after answering Y go on
