Control: reassign -1 console-setup 1.184

This is not a bug in initramfs-tools. The warning comes from console-
setup and is triggered by a change to the German keyboard layout
(from <https://bugs.freedesktop.org/show_bug.cgi?id=102225>).

This is not a bug in initramfs-tools. The warning comes from console-

Indeed, on my system (I use a customised German layout, attached)
console-setup.service fails, even though the layout works under X.org:
$ systemctl status console-setup.service

The interesting bit is
$ grep sharp /usr/share/X11/xkb/symbols/de2
key <AC02> { [ s, S, ssharp, Ssharp ] };
i.e. M-s -> ß and M-S -> ẞ, which correspond as expected to
$ ą
ß (U+00DF, UTF-8 c3 9f ): LATIN SMALL LETTER SHARP S
ẞ (U+1E9E, UTF-8 e1 ba 9e ): LATIN CAPITAL LETTER SHARP S

So Ssharp definitely exists but isn't in <X11/keysymdef.h>:
$ grep -i sharp /usr/include/X11/keysymdef.h
#define XK_ssharp 0x00df /* U+00DF LATIN SMALL LETTER SHARP S */
#define XK_musicalsharp 0x0af5 /* U+266F MUSIC SHARP SIGN */
or, indeed, anywhere?
$ grep -ri ssharp /usr/include/
/usr/include/gtk-3.0/gdk/gdkkeysyms-compat.h:#define GDK_ssharp 0x0df
/usr/include/gtk-3.0/gdk/gdkkeysyms.h:#define GDK_KEY_ssharp 0x0df

So whatever the source of truth w.r.t. keys xinput-or-whatever uses,
console-setup probably needs to use as well, or not error after warnings.

I can also reproduce ths with a German keyboard (XPS 13 9360).

[s***@arcor.de]

Package: console-setup
Version: 1.188

Same here on Debian Buster with console-setup v1.188 and "de" keyboard
layout.
Same as well on Raspbian Buster on RPi2, which has the same
console-setup version and keyboard layout.

I narrowed it down a bid to the "setupcon" command, when configuring the
keyboard:

____________________

Possibly related:

- On the VM, the "dpkg-reconfigure keyboard-configuration" dialog has
French language, even that the current locale is set to "en_GB.UTF-8",
not other locale is even generated, current keyboard layout is "de",
console has UTF-8, Latin1+5, 8x16 chars. I also have disabled APT
package translations disabled. This is not the case on an otherwise
identical Stretch VM with v1.164 packages.

- On the RPi, "dpkg-reconfigure keyboard-configuration" does not even
run interactively, even with "-f dialog" or "-f readline" frontend
actively set. It updates "/etc/default/keyboard", but does not change
any value that was set before. Not sure if it's related. I can't find
any error output/log about it.

Seems the warnings are gone. Neither with update-initramfs nor with
setupcon I get the "WARNING: Unknown X keysym "dead_belowmacron""
messages anymore.

Hi,

for me this message still is displayed:

Dear Maintainer,

On Debian 10 (with console-setup 1.193~deb10u1) running "sudo
update-initramfs -u" produces:
update-initramfs: Generating /boot/initrd.img-4.19.0-9-amd64

This is with my custom XKB keyboard layout where I included the quite a
few "dead_*" X keysyms.

The problem is indeed caused by the Perl script "/usr/bin/ckbcomp" because:

- The script does not support all X keysyms.

- Despite not supporting all X keysyms the supported X keysyms are used
as if the remaining unknown X keysyms are potentially invaild X keysyms.

- On Debian 9 the "/usr/share/initramfs-tools/hooks/keymap" script calls
"/bin/setupcon" via "setupcon --save-keyboard ..." which causes it to
call "/usr/bin/ckbcomp".

- On Debian 10 the "/usr/share/initramfs-tools/hooks/keymap" script
calls "/bin/setupcon" via "setupcon --setup-dir ..." which causes it to
not call "/usr/bin/ckbcomp".

Perhaps the Perl script "/usr/bin/ckbcomp" should be updated to support
all X keysyms or the current supported X keysyms should be used as just
an incomplete whitelist, where the remaining unknown X keysyms are also
potentially vaild keysyms. In other words an info or warning about
unsupported X keysym could be printed only in verbose or debug mode or
not at all.

Bakhelit
