#231970 — need to reinstall pulseaudio every day

hi,
the problem is exactly what says my subject.
every morning, ls /usr/bin/pulseaudio gives:
     ls: cannot access '/usr/bin/pulseaudio': No such file or directory
and I must issue "aptitude reinstall pulseaudio" 
I plan to put the ls command every minute to find when it disappears,
unless somebody can give me an axplanation (and a fix...)

best regards,

When did this start to happen?
    . for years?
    . since installation?

Is this buster?

Are you running any applications, particularly those involving sound,
as root, particularly in response to some previous problem?

Is it just that binary that goes missing, or does apt/dpkg actually
show that the entire package is uninstalled?

The pulseaudio package contains about 216 files. Have they all gone,
or just the one binary? (Run   $ dpkg -L pulseaudio   to list them.)

Cheers,
David.

  hi David,
  I'll answer to-morrow.
  Meantime, may-be my every minute check will have given some usefull information

    I can't answer that now, because I run
    "ls -l /usr/bin/pulseaudio" every minute to find when it disappears,
    and curiously, it didn't disappear this night
    I'll see what happens after removing  the ls command in cron.

Quantum physics principles manifest in software, seen it before. The closer
you look, the more dice you have to roll ☺

But of course Einstein said that in response to the work of Heisenberg and
Bohr. Which was also quite experimental as well as theoretical. Probability
is predictive at the sub-atomic level.

In Schrödinger's Equation of quantum physics, "in practice, the square of
the absolute value of the wave function at each point is taken to define a
probability density function".

  the situation is rather complex  now, after the experiments following
  the Bell's inequalities.
  For example, a lot of people think now that in the Schrodinger's cat
  experiment, the cat is actually alive or dead, before anybody open the door.

But of course death is invariant to physics. In fact it makes the physics
clearer without altering it in any way.

Yet your pulseaudio has disappeared again. So it must result from human
activity. The question remains, which human? You or others? ☺

Hint: You know you're getting old when you find your 2nd wife on dating
sites 😂

And then, "science advances one funeral at a time", attributed, IIRC to
Max Planck, a... physicist. It seems they banded up all together to get
us :-)

Well of course "ex-wife".
Do I look like a Mormon polygamist??
Do I like the Utah wilderness??
Polygamist is a Greek word FYI 😃
My 3rd grade teacher was Mormon...

You could use ``inotify-tools``
https://packages.debian.org/en/buster/inotify-tools
They are based on kernel inotify api:

   I can answer today, as /usr/bin/pulseaudio was not there this morning:
   It's the only missing files. All  other files of the package are still there.
   I'll enable again my monitoring every minute, hoping that observing a process
   will not modify it, as in quantum physics.

  it's a file. Since I re-enabled my monitoring, it didn't disappear.
  wait and see...

Have you done *any* basic, proactive analysis yet?


ls -ld / /usr /usr/bin /usr/bin/pulseaudio

sudo grep -ri pulse /etc/crontab /etc/cron.* /var/spool/cron 

find /lib/systemd /var/lib/systemd /etc/systemd -name '*.timer' \
  -exec grep -i pulse /dev/null {} +


The first one should give 4 lines of output.  Show them.

The latter two don't give any output on my system.  If they give anything
on yours, show it.  And then investigate it.  And then tell us what you
learned.

If you can think of any other places from which an automatic or timed job
might run and do *ANYTHING AT ALL* involving pulseaudio, investigate it.
And then tell us what it was, how you investigated it, and what you
learned.

   I found no other places involving pulseaudio.

   Anyway, it didn't disapear since several days ...

thanks for tour help.

OK, it's good that we can rule out some of the possible causes, like
"permissions are wrong on /usr/bin" or "there's a cron job that
deletes it every week".  We're still left with a mystery, but it's
slightly smaller now.

  actually, it's still a mystery, as I changed nothing in my configuration and pulseaudio
  no more disapears!
