OK, but do you use Ubuntu or Debian or both?

A poster named l0f...@tuta.io replied to me via this mailing list yesterday and 
below is what he wrote (verbatim):

"Cannot remember if you have Gnome installed but you should have a look at 
https://unix.stackexchange.com/a/594287, especially ALL the associated comments 
(click on "Show 7 more comments")."

When I did a *fresh* minimal install of Debian about two years ago, I didn't 
install the whole Gnome DE. Instead, I installed the following packages: xorg 
gnome-core gnome-tweak-tool synaptic file-roller gedit

A few days ago, after reading replies from some posters, I purged the package 
called unattended-upgrades. I don't know how and when it was installed in the 
first place. You see, about two years I chose the option Expert Install 
(without GUI) and during the installation process, I chose the option to not 
install updates automatically.

After reading what was written in the page 
(https://unix.stackexchange.com/a/594287), I disabled the package called 
PackageKit today. Only time will tell if said step works.

By the way, does Ubuntu use the full or stripped-down version of Gnome Desktop 
Environment?

*fresh* = not upgraded from Debian Stretch

It's just a home-grown program that's started from .xsession.
It sets the X background colour in a loop, with excessive
temperatures taking priority over power indications.

It used to be written in shell, but I converted it to python
some years ago when I found that reading the files in
/sys/class/ could fail (3.x kernels). Python's try…except is
easier for me to code than shell's trap mechanism.

I wrote it originally for monitoring whether the AC power
was connected (the brick was unreliable), and the state of
the battery. Temperature came later, for the Dell laptop
I mentioned. That laptop was scrapped last year, and
ironically the Acer laptop it now runs on has a completely
broken power controller (it only runs with AC power).

Woefully underpowered to run even one browser, this Acer
fortunately has a good fan, so it doesn't run too hot. But
it does suffer from symptoms that are somewhat similar to
the OP's—sometimes you have to wait a minute or two (and
avoid touching the touchpad) for things to catch up. But
you can tell it's merely swapping heavily, because the
disk-active light stays lit. (Firefox on buster in ½GB
at 1.5GHz, encrypted /home and 1GB swap.)

Cheers,
David.

Don't get me wrong Tom. I'm perfectly fine with receiving emails in HTML 
format. It's just that a few years ago, when I sent emails with HTML 
formatting, Debian User Mailing List rejected them outright. It took me quite a 
while - about at least two months - trying to figure out why my sent 
HTML-formatted emails were rejected.

I am OK as long as Debian User Mailing List now accepts HTML-formatted emails.

I avoid this wrinkle with a trick that's especially simple when it's
done first thing after installation (but it's easy at any time).

On machine A:

  # ssh-copy-id -i ~/.ssh/id_rsa.pub @hostB

where the sysadminuser¹ is as yet unconfigured for passwordless
login by ssh. On machine B, as sysadminuser:

  $ /bin/su -
  # mv -i /home//.ssh/authorized_keys /root/.ssh/
  # chown 0.0 /root/.ssh/authorized_keys

If sysadminuser already had some keys in authorized_keys,
then root will need to edit the key from the last line of
/home//.ssh/authorized_keys rather than just
moving the file (and make sure you don't leave behind a
backup in /home//.ssh/authorized_keys~).

Alternatively, you can move sysadminuser's authorized_keys
out of the way while you type the lines shown above, and then
move it back. (Stay logged in to sysadminuser while you do this.)

¹ I'm assuming root and sysadminuser are the same person, and others
  don't (yet) have access to the machine.

I haven't managed that rate of rise on a laptop with two cores,
but it could certainly cook your thighs. The attached shows a profile
when I was running the browser on a weather radar site much of the
day. I don't recall whether the machine was switched off from 16:22
to 16:30, or just not running X, but it was certainly switched off
between 16:53 and 17:18 as I was fetching my wife from work through
flooded streets. (The day reached 29°C whereupon over 4 inches of
rain fell.)

One of the posters provided me a link to the post in Unix StackExchange:

By the way, when I did a fresh minimal install of Debian Buster without

following packages: xorg gnome-core gnome-tweak-tool synaptic gedit gdebi

I bet you've got a new profile, thanks to Mozilla continuing the
war on their own users.

Look in ~/.mozilla/firefox for strangely named directories.

Start firefox with -P  to use the profile manager. You may or
may not be able to go back to the old one.

After I have done a fresh minimal install of Debian, I installed the following 
packages:

xorg gnome-core gnome-tweak-tool synaptic gedit gdebi file-roller

As you can see from the above, I did not install the full Gnome desktop 
environment.

The link that you gave me leads to the post in which the description of the 
problem is similar to my issue. It contains helpful information and I have 
taken action based on what the contributors had written. I have disabled 
PackageKit. I have not purged gnome-software as advised by the contributor in 
said post. Why? I am afraid that purging gnome-software may cause my operating 
system to become unusable.

I shall keep you informed if after disabling PackageKit, automatic downloads of 
software/security updates still take place.

firefox problem (OT?)

[ghe2001]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA256

Buster, Firefox-esr, apt says there's nothing to update.

Where does Firefox store the bookmarks?

I had to re-install yesterday, and everything seems to be working. Except my 
years of web bookmarks are gone.  And I can't tell where they are in the 
backups so I can put them back.

I put last week's .mozilla in my home dir, nothing.  I grep'ed the 
.mozilla/firefox files for text that was in one of them, nope.  I searched the 
web and got lots of hits, but they're all about restoring from a fully working 
browser.

Thoughts?  Been there before?

I find serial ports frequently on:

NUC-style machines (not always, but often)
servers (always)
Supermicro motherboards

You might consider getting someone to build you machines based
off of used server motherboards -- that way you will always have
full access to a text console covering BIOS function, booting,
and so forth.

Anything claiming to support IPMI (generic), iDRAC (Dell) or iLO (HP) 
should work nicely for this. Everyone complains that servers are
loud, but it's entirely an artifact of being in a short case
with high-speed fans. Build a desktop-sized system with a server
motherboard and it can be as quiet (or better!) than the next PC
over.

Only if workload stays the same and the system has reached equilibrium.
Temperature can change in a matter of seconds if workload suddenly
changes.

$ cat /sys/class/thermal/thermal_zone2/type
x86_pkg_temp
$ cat /sys/class/thermal/thermal_zone2/temp
47000
$ while : ; do : ; done &
[1] 4739
$ cat /sys/class/thermal/thermal_zone2/temp
63000
$ kill 4739
$ cat /sys/class/thermal/thermal_zone2/temp
49000

That's 15C change in about second on this laptop. My desktop will go
from drawing 17W from the mains when idle, to 160W when maxing out all
8 CPUs and temperature will jump about from 40C to 95C in a few
seconds.

I have found out that grub is very accessible if one has
defined a serial console and there is a working serial port on
the target system.  In this case, both conditions are true.

The next thing one needs is a talking terminal which is
no problem if one has another computer equipped with a serial
terminal program like microcom or what I consider the gold
standard, kermit which apparently has too many dependencies to be
part of the Debian distributions any more.  Kermit has a decent
scripting language so one can save the commands that work, even
the commands that involve entering a huge string in which one
typo means completely starting over again.

This means you can completely repeat all the things that
work each time and feed it all in again in a fraction of a
second.  Talk about working smarter as opposed to harder.

While I call kermit the gold standard, the gold standard
for scripting is expect so one can call unix applications from
the login shell to any valid command, read the output and
generate commands as if one was there.  You can even simulate
human typing rhythms to defeat attempts to detect robots.  I'd
love to see a good CAPTCHA solver with OCR that was so good that
CAPTCHA designers would go out and find honest work but I digress.

This is actually a systemic problem these days when
dealing with sick machines.  Nobody is selling new desktops
with RS-232 native serial ports and that is fine as long as
there is an alternative way such as a bluetooth interface or ssh
network connection.  The dream solution would be a local network
login covering all the lights-out conditions such as BIOS
configuration and failure to boot as in this situation where grub
is confused.

Before I retired, some of our newest servers used
management interfaces and ipmitool where one could turn power on
and off, do BIOS setups and other configuration remotely.  It was
so cool to be able to do those things on a system in another town
without leaving the chair or grabbing a go bag and blowing a
whole day just to flip a couple of switches.  Of course,  
if it was that simple, we usually could call someone we trusted
at one of our remote campuses and ask them to flip the switches
but I'm sure you see the advantage of remote management.

For folks who are blind, you treat all those things as if
they were halfway round the Earth instead of sitting less than 1
meter apart.  They are all headless even if I can extend my arms
and touch both machines.

I think the grubdisk2 GUI app is basically a lost cause
but that's the rule when dealing with accessibility.  When
it's done wrong, you chase down endless rabbit holes all day and
muse as to how there must be some way to turn the sausage machine
backwards and have live farm animals running away from the
other end.

There was an American country and Western song back in
the early seventies which had a line at the end of each verse
that went,

"Work your fingers to the bone
What do ya' get?
Bony fingers."

I think the best course right now is to take my bony
fingers and workup a kermit script to interact with grub and get
it to produce one boot and then use the running system and grub
to fix itself.  So far, nothing else is less work.

I do appreciate your telling me about grubdisk2 because
sometimes, these things turn out to be life savers and you have
to try the rabbit holes to know for sure.

Temperature doesn't change in a matter of one or two minutes, unless you
have a real heat dissipation problem and you'll see in this case the
changes from the time you power it on the temperature will rise fast.

Problem is I can't check the temperature while it's freezing.


You might run a background job that keeps writing the sensors to a file, 
say every 5 minutes, although a really don't know how quickly the 
temperature can change.


That said, this sounds like a long shot to me.

You could, should, consider Wireguard.

- It's faster (less overhead) than OpenVPN
- Config requirements are similar to SSH, rather than OpenVPN
- Easier to add/drop clients than OpenVPN
- Available for all the OSs you mention, and will be in-kernel
  in the next major revisions

You can use any of the remote desktop protocols over the
pseudo-ethernet interface that Wireguard creates. X11, VNC,
Spice, RDP...

xserver-xspice might be the right choice here. Debian and Ubuntu
have virt-viewer clients for spice, Windows and other OS have
clients here: https://www.spice-space.org/download.html

Sorry ! But this is irrelevant... When you have a broken piece of
hardware (or faultry), you first find what's not going good before
investing funds into this machine...
You are telling this guy, go out and invest on something that maybe faulty.
So go buys RAM (that may not be easily transferred) for a laptop that
maybe the motherboard is starting to be faulty, like problem with
capacitors or cold solder.

The RAM and HDD are relevant if and only if, what he describe as a
freezes / crashes ain't one but is more of a huge lag with endless waiting.

Can you reproduce the issue on Debian?

Do CapsLock / NumLed or similar LEDs react (provided there are any)?

Can you ssh into the system, or does it even react to pings from another 
machine?

You might want to do a thorough check of the HDD.

Even if it turns out its ok, provided the rest of the hardware is still 
good, you should consider replacing the HDD with an SSD. The speed 
increase will be significant.

Maxing out the RAM (if any changes are possible) is also a good idea.

Re: Unexplained freezes and crashes, nothing in /var/log/messages

[Polyna-Maude Racicot-Summerside]

When you say "it freeze".
How long have you waited before "pulling the plug" or considering other
way of powering off ?

Have you checked the temperature of your CPU after leaving it running
for a while. Laptop end up with lot of dirt inside and this is not good
for thermal conductivity. So they tend to heat up when they get older
(and not cleaned).

If your system freeze it may be some problem caused by overheating. On
the long run, capacitor get tricky and solder may become problematic.

But first, is this happening only when you have been using the system
for a while ? Because this could point to a problem of overheating.

What are asking here anyway is pretty tough. As we don't have your
hardware in front of us.
