[Bug 2018943] Re: non latin keyboard doesn't suffice for installation

[Olivier Gayot]

Hello,

Thanks for the bug report. Adding ubuntu-desktop-installer.

Subiquity supports configuring the "toggle" key binding. That said there
is no default key binding for it.

For the server installer, the UI shows a dialog to configure the key
binding when a non-latin layout it selected. But it looks like this
dialog is not there on the desktop UI.

The following API call can tell if a given keyboard layout requires a
toggle:

GET a/keyboard/needs_toggle?layout_code=...&variant_code=...

Non-ASCII characters _are_ supported in subiquity. I quickly tested in
the server installer and I could login using greek characters after
install + reboot. I am going to test with the desktop installer as well.

Thanks,
Olivier

Title:
  non latin keyboard doesn't suffice for installation

Status in ubuntu-desktop-installer:
  New
Status in subiquity package in Ubuntu:
  Confirmed

Bug description:
  Using the new ubuntu installer and picking up a non latin keyboard is not possible to finish the installation. The following names:
  -computer
  -user
  are not recognized unless latin keyboard is used.

  edit (adding more info):
  the new installation process of ubuntu is not new under Mantic Minotaur. It had already started from Lunar Lobster where it had some (serious) issues that in the process were getting better and better. Now that a new version is under way, I fired it up and I noticed the following:
  1) the installation doesn't hung and the display of the first image of the installation process has improved a lot, time-wise
  2) it is still slow overall though, without showing any progress
  3) there is no meaning of choosing a non-english keyboard, since installation cannot be completed this way

  the last one is directly related to this bug report: during
  installation one has the option to choose one's keyboard. I can do so
  by typing only a couple of characters and greek keyboard is readily
  recognized. I follow the slideshow with the available options until
  the credentials of the new installation are required. Typing any name
  as my name, using different keyboards chosen at the beginning of the
  installation (either greek or english), that process is working fine.
  The problem arises when the computer name and user name is required:
  it doesn't pick up non-english characters. Maybe in general non-latin
  ones.

  In old ubuntu versions (e.g. 10.10) the user has the ability to switch
  keyboards by tapping Alt+Shift during the installation process. This
  is not the case now. I tried also Super+space to no avail.
