How do I install ntpd-rs on a Debian 13-based operating system like LMDE7 with Cinnamon Desktop via terminal?

[Nihon-Ryori]

Given is a common Debian 13 based LMDE7 system, with Cinnamon Desktop, whose time reference is based on systemd-timesyncd and systemd-timedatectl.

lsb_release -d
Description:	LMDE 7 (gigi)

echo $XDG_CURRENT_DESKTOP
X-Cinnamon

In the ntpd-rs documentation I found instructions for migrating from chrony, ntpd and NTPsec to ntpd-rs, but no installation instructions for the case requested here that were apparent to me:
* https://docs.ntpd-rs.pendulum-project.org

I expect that before installing ntpd-rs, even on a perfectly functioning system, you will probably need to disable or perhaps even uninstall certain things, and that simply entering the following four commands in the terminal will not be sufficient:

sudo apt update
sudo apt install ntpd-rs

sudo systemctl enable ntpd-rs
sudo systemctl start ntpd-rs

I'm also unsure which of the two—or perhaps just one of them—of the following files is used for configuration, and if they aren't present after installation, should they simply be created manually?:

/etc/ntpd-rs/ntpd-rs.conf
/etc/ntpd-rs/ntp.toml

Sample configuration of the /etc/ntpd-rs/ntp.toml file

• https://github.com/pendulum-project/ntpd-rs/blob/main/ntp.toml

Man page for the file /etc/ntpd-rs/ntp.toml

• https://docs.ntpd-rs.pendulum-project.org/man/ntp.toml.5/

Furthermore, I don't know how to test whether ntpd-rs is correctly obtaining the time via NTS.

Thank you for your help.

It appears that the relevant section to add to the ntpd-rs installation guide for installing ntpd-rs on Debian 13-based distributions such as LMDE7 is as follows:

sudo apt install ntpd-rs

sudo systemctl enable --now ntpd-rs

ntp-ctl status

Perhaps this should be added to the documentation on the following page:

• https://docs.ntpd-rs.pendulum-project.org/guide/installation/

The debian repositories can be significantly behind, which is why we don't recommend them in our documentation. The installation instructions in the guide you quoted in your second message will work just fine on any debian system, and will take care of dealing with conflicting time daemons so long as those are installed through the package manager.

However, if you feel anything in that section is unclear or could use additional clarification, feel free to open a PR expanding on those instructions.
