I ran it once, but my terminal native language went back to Finnish. I've tried unsuccessfully .bashrc and .profile.
I have followed the thread here about How to set all locale settings in Ubuntu. I have also tried to setup English as locale:
sudo update-locale LANG=en_EN.UTF-8 LC_MESSAGES=POSIX
But output:
*** update-locale: Error: invalid locale settings: LC_NAME="fi_FI.UTF-8" LC_TIME="fi_FI.UTF-8"
LC_IDENTIFICATION="fi_FI.UTF-8" LC_NUMERIC="fi_FI.UTF-8"
LC_MESSAGES=POSIX LANG=en_EN.UTF-8 LC_MEASUREMENT="fi_FI.UTF-8"
LC_ADDRESS="fi_FI.UTF-8" LC_PAPER="fi_FI.UTF-8"
LC_MONETARY="fi_FI.UTF-8" LC_TELEPHONE="fi_FI.UTF-8"
Where can you put export LC_ALL=C?
