I have had this problem since I downloaded Debian 10 KDE Plasma. Any time I run a program I get warning errors about the language settings. I have ran all of the commands to set the language settings such as:
export LANGUAGE=en_US.UTF-8 export LANG=en_US.UTF-8 export LC_ALL=en_US.UTF-8 locale-gen en_US.UTF-8 sudo locale-gen en_US.UTF-8 dpkg-reconfigure locales sudo dpkg-reconfigure locales
but every time I re-log in or restart my computer the language settings are gone and I get the same errors/warnings in the programs. Some programs won't run without the settings. A concrete example is when I run R this warning shows:
During startup - Warning messages: 1: Setting LC_CTYPE failed, using "C" 2: Setting LC_COLLATE failed, using "C" 3: Setting LC_TIME failed, using "C" 4: Setting LC_MESSAGES failed, using "C" 5: Setting LC_MONETARY failed, using "C" 6: Setting LC_PAPER failed, using "C" 7: Setting LC_MEASUREMENT failed, using "C"
Any help on making the settings stay and why this is even happening?
