Updates

Manual Update

Manual updates usually work the same way as the initial installation. So you simply download the latest release:

• SNClient Releases Page

Then install the file as described on the install page.

Automatic Updates

SNClient Automatic Updates

If possible, use the operating system’s own update mechanism to automatically install updates. If not, SNClient can update itself periodically.

Configuration:

Create or edit /etc/snclient/snclient_local.ini (on Windows: C:\Program Files\snclient\snclient_local.ini)

[/settings/updates]
automatic updates = enabled
automatic restart = enabled

This will update SNClient to the latest stable release.

If you want to use development builds, for example on test systems, you can add the dev channel as well.

[/settings/updates]
automatic updates = enabled
automatic restart = enabled
channel = stable,dev

[/settings/updates/channel/dev]
; github token - the dev channel requires a github token to download the update
github token = GITHUB-TOKEN...

In order to use the dev channel, you need to create a GitHub token here: github.com/settings/tokens

Unfortunately it is not possible to download the build artifacts without a token.

Note: The SNClient self-update works on Linux, but cannot safely transfer the required capabilities. So it will only fully work if you don’t require any capabilities.

Debian / Ubuntu

On Debian and Ubuntu you can make use of the unattended-upgrades package.

• wiki.debian.org

Install the package:

#> apt install unattended-upgrades

Once installed you can add labs.consol.de to the list of sites used for automatic updates:

/etc/apt/apt.conf.d/50unattended-upgrades

Unattended-Upgrade::Origins-Pattern {
    // extend origin patterns with the labs repository
    "site=labs.consol.de"
}

Then activate periodic updates by adding a cronjob entry to the root crontab:

#> crontab -e

And add:

0 * * * * /usr/bin/apt-get -qq update && /bin/bash -lc "/usr/bin/unattended-upgrade"

To install updates at the start of every hour.

Or see the wiki.debian.org for other ways.
