Unfortunately, this bug is more dangerous than it seems. I've tested
the languages below and they all failed:
* Hebrew
Keymap: hebrew.kmap
Charset (_in keymap_, not in languagelist): iso-8859-8
Result: Gave the warning 'unknown keysym "doubleunderscore"'
Totally refused to load keymap at boot!
* Lithuanian
Keymap: lt.kmap
Charset: iso-8859-4
Result: Same as Turkish (keymap loaded, but will not be functioning
properly)
* Latvian
Keymap: lv-latin4.kmap
Charset: iso-8859-4
Result: Same as Turkish
I've retested these languages by applying the following one line patch:
(/usr/lib/prebaseconfig.d/70kbd-chooser)
db_get debian-installer/serial-console
if [ "$RET" = "false" ] ; then
apt-install console-tools console-data console-common
- chroot /target install-keymap $KEYMAP
+ kbd-mode -a; chroot /target install-keymap $KEYMAP; kbd-mode -u
fi
and the problem was resolved. According to these facts, let me
summarize the whole picture:
* We had applied a critical patch to resolve the bugs: #251550, #251231,
#252109 (keyboard freezes for high ascii characters). From that time,
keyboard has been used in Unicode mode in d-i.
* But as stated in #276752, switching to unicode mode produces a
side-effect for all languages which use console-tools and have a
charset declared in keymap different from iso-8859-1, iso-8859-15 and
utf-8. Note that most of the cyrillic languages (using the
console-cyrillic) and asian languages (using jfbterm) does not suffer
from the problem. In fact, only a few languages that I know of:
Turkish, Hebrew, Lithuanian and Latvian are directly affected.
* Switching temporarily to ascii mode before invoking 'install-keymap'
(and then reswitching to the unicode mode) seems to be the most simple
solution, till we find a fix for #276548. As I said before, I've
succesfully tested this workaround for the affected languages.
* Instead of fixing the problem for affected languages only, I suggest
to use brute-force which means to always switch to ascii mode before
keymap installation, hence my patch.
* The workaround I proposed should not affect the languages using
iso-8859-1/15 and utf-8, because this workaround means to return
temporarily back to the old behaviour (the one before applying the
patch to fix the keyboard freezes). Nevertheless we should perform a
test. Hence I CC'ed this mail to Christian (iso-8859-1/15) and
Konstantinos (utf-8). Could you check the French and Greek keyboards
_after the installation_ by first applying the patch attached to the
/usr/lib/prebaseconfig.d/70kbd-chooser in d-i phase?
