You need to change/update the sources list from russian to english.
#!! Create /etc/apt/sources.list
deb http://ftp.ru.debian.org/debian wheezy main contrib non-free
deb http://ftp.ru.debian.org/debian wheezy-updates main contrib non-free
deb http://security.debian.org/ wheezy/updates main contrib non-free
#updated sources list /etc/apt/sources.list
deb http://ftp.us.debian.org/debian stable main contrib non-free
deb http://ftp.debian.org/debian/ wheezy-updates main contrib non-free
deb http://security.debian.org/ wheezy/updates main contrib non-free
cd /etc/apt/sources.list
nano sources.list
change first two lines that contain ftp.ru.debian…
Save and close out.
apt-get update
Change you local language. You must be root for this to work.
I found it here: https://wiki.debian.org/ChangeLanguage
env | grep LANG
export LANG=en_US.UTF-8
dpkg-reconfigure locales
A window will ask you to select the languages you want to have available. Choose your own.
Changes may not show immediately, a reboot will be needed.
Let us know how it goes.
