Ubuntu installer selects a single keyboard layout, cannot type English during installation

Ubuntu uses a new installer that is based on Flutter. Ubuntu 24.04 is the first Long Term Support (LTS) to use the new installer, and now Ubuntu 26.04 is the second LTS. Ubuntu 26.04 is currently being developed, and currently any bugs/issues, big or small, are being resolved. All is fine when you rewrite software. [ ]
