Resolved: perl: warning: Please check that your locale settings:
When working with ubuntu, sometimes when you remote ssh into a server you get a bunch of locale errors which are pretty annoying. Fortunately, when using Ubuntu 18 you get a message when you login that is rather helpful:
_____________________________________________________________________ WARNING! Your environment specifies an invalid locale. The unknown environment variables are: LC_CTYPE=UTF-8 LC_ALL= This can affect your user experience significantly, including the ability to manage packages. You may install the locales by running: sudo apt-get install language-pack-UTF-8 or sudo locale-gen UTF-8 To see all available language packs, run: apt-cache search "^language-pack-[a-z][a-z]$" To disable this message for all users, run: sudo touch /var/lib/cloud/instance/locale-check.skip _____________________________________________________________________
so, the key here is that your client machine has a locale that your ubuntu server is struggling to grasp. Sadly, you follow the instructions just to run across this:
$ sudo apt-get install language-pack-UTF-8 [sudo] password for : Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package language-pack-UTF-8
$ sudo locale-gen UTF-8 Error: 'UTF-8' is not a supported language or locale
perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = "en_US.UTF-8", LC_CTYPE = "en_US.UTF-8", LANG = "en_US.UTF-8" are supported and installed on your system.
which makes you wonder… if they don’t work why did I say the message was rather helpful? Well, because it points us in the right direction: We need to install the language pack somehow. Well, it turns out I am using a Mac and it is in spanish, so Ubuntu is unable to translate that into one of its locales. So, take the example below:
export LC_ALL="en_US.UTF-8" export LC_CTYPE="en_US.UTF-8" sudo dpkg-reconfigure locales
This will tell it to default to en_us and call it a day. In my case, I ran in order to get the language code for Spanish/Mexico which is:
es_MX.UTF-8. Make sure you install the language while you are at it on the
dpkg-reconfigure locales screen before you try to run the following commands. That means you can look yours up if you are using a different language and plug it in like so:
export LC_ALL="es_MX.UTF-8" export LC_CTYPE="es_MX.UTF-8" sudo dpkg-reconfigure locales
and you should be golden now!
