When using the text installer on an equivalent of a physical console such as a web-based remote keyboard, video monitor, mouse, or VirtualBox console, the installer displays text in English even if you have chosen another language during the boot from the install media. The installer displays text in English to avoid a garbled display of non-ASCII characters.
The text installer displays localized text only on an equivalent of a serial console, for example, a service console based on SSH or telnet.
Workaround: None.
