Keyboard layout is wrong. Solution: During the wizard setup, specify the correct keyboard map (e.g., us , uk , de ). You can also edit /etc/kbd/lang after boot if you have persistent changes. Upgrading from 5.4.0 to a Newer Version While 5.4.0 is stable, you may eventually need to upgrade. The Porteus-Kiosk team releases major versions (5.x, 6.x). Because the system is stateless, upgrading is as simple as downloading the newer ISO and writing it to your boot media.

If you have a PC that you want to turn into a simple web terminal—without the constant fear of viruses, user errors, or system crashes—this ISO is your solution. It requires minimal hardware, zero maintenance, and boots faster than a smart TV loads its OS.
