Summary: check_apt: clarify that it doesn't upgrade per default
Initial Comment:
(Roughly) From: http://tracker.nagios.org/view.php?id=302
Hi.
check_apt uses its "--upgrade" option per default:
-U, --upgrade=OPTS
[Default] Perform an upgrade. If an optional OPTS argument is provided,
apt-get will be run with these command line options instead of the
default (-o 'Debug::NoLocking=true' -s -qq).
Note that you may be required to have root privileges if you do not use
the default options.
I was quite confused by this, given the meanings of upgrade (install new packages) and update (get information about new packages) in Debian.
The following seems to be true:
- Using the upgrade mode in APT (and therefore the --upgrade option to the plugin) is really required, even to just get a list of upgradable packages.
So this really needs to be the default.
- No upgrades (in the sense of installing packags) are however executed, given the options (-o 'Debug::NoLocking=true' -s -qq). This is true for both, normal users (obviously) and root.
In order to clear things up, I'd suggest to add a notes that:
- the --upgrade option of the plugins (with it's default OPTS) doesn't do package upgrades (in the sense of installing new ones), neither as root nor as normal user.
and optionally:
- the --update option (and upgrade mode of APT) is needed even to just get a list of upgradable pacakges.
Cheers,
Chris.
