After installing Linux Mint, these are the things you may want to keep it up to date and configured properly.
Get Updates
Open Update Manager by clicking on the shield icon on the bottom right-hand corner (see inset) and click on the Install Updates button.
Or from the terminal run the following command:
sudo apt-get update && sudo apt-get upgrade
Set UTF-8 Locale
Open Terminal and type in this command:
ls /usr/lib/locale
You will see this result.
# ls /usr/lib/locale/ C.UTF-8 locale-archive
Now, type in the following command:
sudo locale-gen --purge --no-archive # ls /usr/lib/locale/ C.UTF-8 de_LI.utf8 en_CA.utf8 en_IN en_US.utf8 de_AT.utf8 de_LU.utf8 en_DK.utf8 en_NG en_ZA.utf8 de_BE.utf8 en_AG en_GB.utf8 en_NZ.utf8 en_ZM de_CH.utf8 en_AU.utf8 en_HK.utf8 en_PH.utf8 en_ZW.utf8 de_DE.utf8 en_BW.utf8 en_IE.utf8 en_SG.utf8
