[DNG] chimaera to daedalus upgrade

[fraser kendall]

Hello,

In the middle of a dist-upgrade and got this error:

Preparing to unpack .../nodejs_16.15.1+dfsg-1_amd64.deb ...
Unpacking nodejs (16.15.1+dfsg-1) over (12.22.12~dfsg-1~deb11u1) ...
dpkg: error processing archive
/var/cache/apt/archives/nodejs_16.15.1+dfsg-1_amd64.deb (--unpack):
trying to overwrite '/usr/share/systemtap/tapset/node.stp', which is

Errors were encountered while processing:
/var/cache/apt/archives/nodejs_16.15.1+dfsg-1_amd64.deb E: 

Sub-process /usr/bin/dpkg returned an error code (1)

reluctant to just reboot and hope.

Is this at all interesting or is is it simply artefactual?

best

You can find these files in the subdirectories:

/sys/devices/system/node/node0/hugepages/hugepages-*/

The path you gave is per numa node. It is possible to set different numbers of
hugepages on each numa node. The per system information is here:

/sys/kernel/mm/hugepages/hugepages-*/nr_hugepages

(or in /proc/meminfo)


Read the paragraph "Per Node Huge Pages Attributes" in the link:

https://github.com/torvalds/linux/blob/master/Documentation/admin-guide/mm/hugetlbpage.rst
  


saying:

[...]

  A subset of the contents of the root huge page control directory in sysfs,
  described above, will be *replicated* under each the system device of each
  NUMA node with memory in:

 /sys/devices/system/node/node[0-9]*/hugepages/

[...]

The root huge page control directory in `sysfs` is:

  /sys/kernel/mm/hugepages

For each huge page size supported by the running kernel, a subdirectory 
will exist, of the form:


  hugepages-${size}kB

And you'll find the same subdirectories replicated among the numa nodes with 
memory in:

/sys/devices/system/node/node[0-9]*/hugepages/


Cheers,

Aitor.

systemd does no black magic to initialize your audio hat, it just loads the 
correct kernel module. Followed the steps in the manual (chapter 3) 
https://datasheets.raspberrypi.com/iqaudio/iqaudio-product-brief.pdf and see it 
it's autodetected. If not, load the module by hand.

[DNG] Lennart now working for Microsoft

[Edward Bartolo via Dng]

Let me understand... So, this excellent coder first grabs the
opportunity offered to him by RedHat, and now, after the latter made
him rich, he is leaving  them! Please, anyone explain to me, how can
anyone extend a day beyond the usual 24 hours? Systemd is not a simple
game like the many one can find, it is literally a very complex piece
of software with many functions that hardly can be logically imagined
to be produced by the same project. This latter fact, is asking for
more systemd problems.

Regrettably, I have it running on my raspberry pi mini-computer
because I could not find a way to let the OS recognise and use an
IQAudIO DAC PRO hat (a sound card). If Devuan can do it, that would be
the death knell of my installation using the blessed systemd.

Thanks to all for using and supporting Devuan.

Hi,
in my debian to devuan migration script I hit the same problem
and resolved it like this:

# ntpdate is deprecated in debian but still exists in
# bullseye repos so we still use it here.
# In the future we will  need to switch to
# ntpsec-ntpdate or sntp -S pool.ntp.org
# this is less ideal as they have more dependencies.
# INSTALL NTPDATE IF NEEDED
NTPDATE=$(command -v ntpdate-debian)
if test -x "$NTPDATE" ; then
echo "ntpdate-debian is already installed...good"
# Wrong date and time is one of the causes of failure of apt update
# and subsequent devuan deb packages download which breaks
# the migration process, so we ensure that date and time are set 
correctly
else
echo "Installing ntpdate-debian"
apt install ntpdate > /dev/null 2>&1
fi
echo "Setting date and time with ntpdate-debian"
ntpdate-debian pool.ntp.org
# Allow time change to propagate
sleep 5

Hope this helps.

Ciao,
Tito
