Package: ntp Version: 1:4.2.8p10+dfsg-5 Severity: normal Hi,
with one of the recent updates ntp lost acess to my local DCF clock. It took me quite a while to find out that the correct may to regain access to the device was to set @{NTPD_DEVICE}="/dev/ttyUSB[0-9]*" in /etc/apparmor.d/tunables/ntpd Please be so kind to mention the above file and the tunable NTPD_DEVICE in README.Debian or NEWS.Debian to help people like me with local clocks. When I googled the issue, the most prominent results were to disable any SElinux / apparmor. And this is definitely the worst option ;-) Thanks for maintaining ntp in Debian Peter -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 4.13.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages ntp depends on: ii adduser 3.116 ii dpkg 1.19.0.4 ii init-system-helpers 1.51 ii libc6 2.25-3 ii libcap2 1:2.25-1.2 ii libedit2 3.1-20170329-1 ii libopts25 1:5.18.12-3 ii libssl1.1 1.1.0g-2 ii lsb-base 9.20170808 ii netbase 5.4 ii tzdata 2017c-1 Versions of packages ntp recommends: ii perl 5.26.1-3 pn sntp <none> Versions of packages ntp suggests: ii ntp-doc 1:4.2.8p10+dfsg-5 -- Configuration Files: /etc/apparmor.d/tunables/ntpd changed: @{NTPD_DEVICE}="/dev/ttyUSB[0-9]*" -- no debconf information
