ubiquity (1.1.30) edgy; urgency=low * Add /usr/lib/ubiquity/console-setup/locale wrapper that overrides the output of locale with the value of debian-installer/locale if set; this encourages console-setup to select an appropriate keyboard layout (closes: Malone #60067). * Don't set PARTMAN_UPDATE_BEFORE_COMMIT for automatic partitioning. * Run partman-commit while generating the installation summary to make sure that we have a partitioning summary even for manual partitioning (closes: Malone #61572). Take care to stop partman-commit proceeding past the confirmation question. * Don't reset the locale or run localechooser again if the country selected on the timezone page isn't one for which we have a locale in the current language (closes: Malone #61387). * Add/update .desktop file translations from Rosetta: Arabic, Belarusian, Czech, Kashubian, Spanish, Estonian, French, Frisian, Irish, Luxembourgish, Lithuanian, Macedonian, Malay, Portuguese (Brazil), Slovak, Swedish, Tajik, Ukrainian, Chinese (Taiwan). * Add/update translations from Rosetta: Afrikaans, Amharic, Bulgarian, Bengali, Breton, Catalan, Czech, Kashubian, Welsh, Danish, German, Divehi, Dzongkha, Greek, Esperanto, Spanish, Basque, Persian, Finnish, French, Irish, Galician, Hebrew, Hindi, Croatian, Hungarian, Indonesian, Icelandic, Italian, Japanese, Georgian, Khmer, Kurdish, Kirghiz, Lithuanian, Latvian, Malagasy, Macedonian, Malay, Norwegian Bokmål, Dutch, Occitan, Polish, Portuguese, Portuguese (Brazil), Romanian, Russian, Northern Sami, Slovak, Slovenian, Serbian, Swedish, Tamil, Thai, Tagalog, Turkish, Chinese (China), Chinese (Hong Kong). * Automatic update of included source packages: base-installer 1.63ubuntu5, localechooser 1.20ubuntu7, partman-base 90ubuntu6. -- Colin Watson <[EMAIL PROTECTED]> Mon, 9 Oct 2006 21:15:10 +0100 ** Changed in: ubiquity (Ubuntu) Status: Fix Committed => Fix Released -- [edgy knot 3] selecting zh_TW produces zh_CN https://launchpad.net/bugs/61387 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
