Bug 381521

What is your system locale? (you can paste the output of the `locale` command as user)

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=ru_BY.UTF-8
LANGUAGE=ru:en_US
LC_CTYPE="ru_BY.UTF-8"
LC_NUMERIC="ru_BY.UTF-8"
LC_TIME="ru_BY.UTF-8"
LC_COLLATE="ru_BY.UTF-8"
LC_MONETARY="ru_BY.UTF-8"
LC_MESSAGES="ru_BY.UTF-8"
LC_PAPER="ru_BY.UTF-8"
LC_NAME="ru_BY.UTF-8"
LC_ADDRESS="ru_BY.UTF-8"
LC_TELEPHONE="ru_BY.UTF-8"
LC_MEASUREMENT="ru_BY.UTF-8"
LC_IDENTIFICATION="ru_BY.UTF-8"
LC_ALL=

Did you set the locale through the systemsettings or when you installed Debian?

Please make sure that the locale exists (dpkg-reconfigure locales).

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

How do I fix this??

sudo dpkg-reconfigure locales

        LANGUAGE = "ru:en_US",

Did dpkg-reconfigure ask you any question? I should have seen a list box with all the available locales, and you should have been asked to set the default locale.

I've chosen locales "en_US.UTF-8" and "ru_RU.UTF-8".
As default I set "ru_RU.UTF-8", but it doesn't effect. When I run dpkg-reconfigure second time it shows the same errors and warnings like at first time.

There is still a pending question: did you set the "ru_BY.UTF-8" locale through  systemsettings ("Regional Settings" -> "Formats")?
Do you see a ru_BY locale in Debian, from dpkg-reconfigure locales? If not, you should change the settings in systemsettings to match an existing locale.

thanks, it's worked :) It were much locales on systemsettings and part of them was writed with russian letters(I didn't notice it at first). So it takes time to find ru_RU there... But now everything is working.

Btw, on the top of okular's window writed some ugly code instead of file's name. But that's not error, just a little notice :) And that is occured not in all pdf-files. I've find only one file with such problem yet.

it was system misconfiguration
