Package: libc6 Version: 2.28-2 Severity: minor While upgrading libc6 from 2.27-8 to 2.28-2, I saw this:
| Checking for services that may need to be restarted... | Checking init scripts... | /var/lib/dpkg/tmp.ci/preinst: 320: /var/lib/dpkg/tmp.ci/preinst: runlevel: not found That's libc6's preinst using runlevel. I also saw this: | Checking for services that may need to be restarted... | Checking init scripts... | /var/lib/dpkg/info/libc6:amd64.postinst: 81: /var/lib/dpkg/info/libc6:amd64.postinst: runlevel: not found | Nothing to restart. That's the same thing for postinst. The message is completely harmless. It's from debian/script.in/nsscheck.sh and tells. When runlevel is not available, we're not running any of sysvinit, systemd or runit and very likely no services are running. In that case, the result is irrelevant and the only negative effect is the message. The upgrade proceeds successfully. Helmut
