[Romain Dessort (Evolix)]

Package: varnish
Version: 4.0.2-1
Severity: minor
Tags: patch

Hello,

If varnishlog/varnishncsa daemons are not launched (the default after
installing Varnish), logrotate output the following errors when trying to run
invoke-rc.d reload:

    /etc/cron.daily/logrotate:
    Job for varnishlog.service failed. See 'systemctl status varnishlog.service' and 'journalctl -xn' for details.
    invoke-rc.d: initscript varnishlog, action "reload" failed.
    error: error running non-shared postrotate script for /var/log/varnish/varnish.log of '/var/log/varnish/varnish.log '
    Job for varnishncsa.service failed. See 'systemctl status varnishncsa.service' and 'journalctl -xn' for details.
    invoke-rc.d: initscript varnishncsa, action "reload" failed.
    error: error running non-shared postrotate script for /var/log/varnish/varnishncsa.log of '/var/log/varnish/varnishncsa.log '
    run-parts: /etc/cron.daily/logrotate exited with return code 1
