 Nothing will go wrong, but it does not hurt to [[other:win10wsl#backup_of_a_full_linux_installation|save an image of your full installation]], in case you want to try some really different settings later.

-WSL will automatically try to use in the terminals the same language as the one used by the Windows 10 computer ([[https://docs.microsoft.com/en-us/windows/wsl/troubleshooting#changing-the-display-language|ref]]), but this could lead later to some difficult to debug **side-effects** when you connect to remote Linux servers (e.g. the ''sort'' command may give different results !).

+It is **safer** to [[https://docs.microsoft.com/en-us/windows/wsl/troubleshooting#changing-the-display-language|force the Linux installation to use a standard English localization]]. The ''update-locale'' command will change the content of the ''/etc/default/locale'' file

+After updating the system //localization// (and possibly restarting ''wsl'' with ''%%wsl --shutdown%%''), open the [[other:win10wsl#opening_a_terminal|available terminals]] and type ''echo $LANG'' in order to check that are indeed getting ''en_US.UTF8''
+If you are still not getting ''en_US.UTF8'' in some terminals (e.g. you are still getting ''C.UTF-8''), you can check if you can override the //localization// options in the terminals settings. Check the [[other:win10wsl#the_wsltty_terminal|Text options of the WSLtty terminals]]
 ==== Package management ====
+=== How does it work ? ===
+  * **Ubuntu applications** are distributed through package files in **//Debian// format** (''.deb'' files) that are found in [[https://help.ubuntu.com/community/Applications#Software_repositories|software repositories]]
+  * High level package management tools such as ''aptitude'' or ''synaptic'' rely on ''apt'' which, itself, relies on ''dpkg'' to manage the packages in the system
+    * The ''apt'' tool merges functionality of ''apt-get'' and ''apt-cache'' and by default has a fancier colored output format, making it more pleasant for humans. For usage in scripts or advanced use cases, ''apt-get'' is still preferable or needed
+    * ''apt*'' tools and ''dpkg'' are pre-installed on Ubuntu
+    * [[https://www.debian.org/doc/manuals/debian-faq/pkgtools.en.html#aptitude|aptitude]] can be used on the command-line or through a text-based interface.
+      * You do not need to have an [[other:x_conf|X server]] running to use ''aptitude'', therefore aptitude can be used in the early stages of a Linux installation, or on a remote Linux computer
+    * [[https://www.debian.org/doc/manuals/debian-faq/pkgtools.en.html#synaptic|synaptic]] is a graphical package manager
+      * You need to have an [[other:x_conf|X server]] running in order to use it
+  * All the details can be found in [[https://www.debian.org/doc/manuals/debian-faq/pkgtools.en.html|The Debian package management tools]]
 [[https://www.howtogeek.com/63997/how-to-install-programs-in-ubuntu-in-the-command-line/|apt-get tutorial]] if you are more used to Fedora/RedHat ''yum''/''dnf'' and //rpm// packages
