Automatic updates

Porteus Kiosk is very well secured but it does not have 'automatic updates' service enabled by default. This is an important feature which provides security patches, updated software components (kernel, browser, libraries/utilities) and brand new system features. Public ISOs are released about two times per year which may not be enough for companies/institutions or even a single users where security and 'up to date' software are critical from a private or business point of view.

Taking this into mind, we have introduced a paid subscription for those who want to keep their systems updated and secured 365 days a year. We are targeting the 'setup and forget' approach which means that you need to setup your kiosk only once through our Kiosk Wizard, and then it updates automatically without any user intervention. Only a reboot is required so updated components such as kernel or browser can be loaded into PC memory.

Automatic updates allows software freezes and downgrades. It is possible to freeze the linux kernel at specific version and upgrade it when certain bugs are resolved upstream. It is also possible to freeze, for example, Firefox but keep upgrading other system components. The automatic updates service is very flexible - when in doubt please query for additional information.

You have an opportunity to sign up for a 1 month free trial before buying the subscription.

When activating 'automatic updates' you are automatically signed to our support service which means that you are eligible to receive a software/hardware related help during the whole subscription period without additional charge.

Real time changelog for security fixes, software upgrades and new features implemented in the system are presented at this address: automatic updates changelog.

  • Kiosks signed to the automatic updates service must be able to access domain on ports 80 and 443. Please make sure that your firewall is not blocking these ports and our domain.

  • How do automatic updates work?

  • Kiosk boots and does an MD5 sum check of all system components.
  • Once the network is fully initialized, kiosk contacts our server which has a list of MD5 sums for the latest available components.
  • If there is a mismatch between local and remote sums, then the updated component is downloaded from our server, new ISO is created on the fly and burnt automatically on the hard drive.
  • After reboot the system is fully updated and secured.

  • Please check out following video presenting how Porteus Kiosk performs an update: link


  • System works in full rolling-release development model.
  • Kiosk is kept up to date all the time.
  • Only updated components are downloaded over the network which saves time and bandwidth required for doing an update (short downtime).
  • Everything is done automatically, no need to burn the ISOs manually anymore.
  • Kiosk config is preserved so there is no need to run the Kiosk Wizard and repeat configuration steps.
  • Automatic updates enhances security as MD5 sums are monitored and every mismatch brings a clean component from our server.

  • Limitations

  • Automatic updates can be enabled only for usb/hard drive installations and wont work for CDs/DVDs or a kiosks booted over network (PXE boot).
  • There is no possibility to perform manual kiosk ISO customizations due to MD5 sum mismatches with components kept on our server. Modifications authorized through our customized builds service are still possible when automatic updates are enabled. Please mind that extra charge will apply in case when custom component requires additional maintenance effort during updates.
