ntpdate installation in moode audio - Falconcrest - 11-06-2024
Hi,
I would like to synchronize my two Raspberry Pi's, on which moode Audio is installed, with my time server in the home network.
Preferably I would like
0 * * * * /usr/sbin/ntpdate -s XXX.XXX.XXX.XXX
in crontab -e.
But now when I try to install ntpdate, various other files are supposed to be uninstalled because they are no longer needed.
Therefore I have canceled the installation for the time being.
What is the best way to do this or can I specify my own time server somewhere else under moode?
Thanks for any suggestions.

It's not clear to me why you need this degree of time synchronization but since you would like to, let's consider what happened.
I just tried installing ntpdate on a moOde 9.1.4 player. The package manager apt offered to install it along with 3 related packages
Code:
The following additional packages will be installed:
ntpsec-ntpdate ntpsec-ntpdig python3-ntp
The following NEW packages will be installed:
ntpdate ntpsec-ntpdate ntpsec-ntpdig python3-ntp
0 upgraded, 4 newly installed, 0 to remove and 12 not upgraded.When I accepted the proposed install, apt did so without suggesting there were now packages no longer needed which could be removed.
What release of moOde are you working with and have you installed anything else on it?
As to the message in question, it's merely advisory---you can accept or reject the removal. If it makes you uneasy, just leave them installed.
Regards,
Kent

Hi Kent,
Ok, the usefulness of my idea is debatable, but since I have set it up this way on all my different RPI`s, the Pi's with moode audio should not be missing.
The installation of ntpdate on an RPi 2 with moode audio version 8.3.9 worked now
without any problems.
However, the installation on an RPi 3B+ resulted in the following message:
Host: moOde
RPiOS: 12.6 Bookworm 64-bit | Linux: 6.6.51 64-bit
Model: Pi-3B+ 1GB
Audio: HiFiBerry DAC+

But note what is actually said

Use 'sudo apt autoremove' to remove them.Dunno where those packages came from. Was this an in-place update of a previous moOde release?.
Anyway, just don't run sudo apt autoremove if you don't want to remove them.
As an aside, obviously sudo su can allow you to run interactive commands as root but it's considered better practice just to run the commands prefaced by sudo.

Kent

Why? Let them sync using the default OS config and be done with it. I suspect that you are over-thinking things here.
RE: ntpdate installation in moode audio - Falconcrest - 11-06-2024
I mean, it was a new installation 1-2 versions of moode audio ago with prior export of the settings and subsequent import into the new installation. But you are right, 1-2 times an in-place upgrade has been done in the meantime.
I will take the sudo su thing into account in future.
Another slightly different question:
Is it still valid to avoid apt update, apt upgrade etc. and better to work only with the updates of moode Audio?
RE: ntpdate installation in moode audio - Falconcrest - 11-06-2024
I admit, it's perhaps a little playful after all! ?

Yes.
P.S.
all those qt packages look weird to me; I think I've also seen a gtk-something one. They are not, AFAIK, in the moOde distribution. Maybe you tried to install some software that pulled them in...?
RE: ntpdate installation in moode audio - Falconcrest - 11-07-2024
I don't really know where the packages could come from.
The only thing that is certainly different to a "standard" installation is that I don't use an SD card, but an SSD connected via USB and an RTC is installed.

To quote my farmer grandfather, “if it ain’t broke, don’t be fixing it.”
That was usually directed at my uncle who was always fiddling with his tractor.
I expect those packages were in an earlier release of moOde. However they got there, they can stay if nothing else in the current release is complaining or they can go if none of them is supporting some app which depends only on one or more of them. If you’re uncomfortable removing them, then don’t.
If you make a backup of your current configuration first, then the worst that can happen is you have to make a fresh install of moOde 9.1.4 and reload the backup.

Kent
