In many of my Digital Ocean's droplet I sometimes get this whenever I'm installing something:
perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LC_TIME = "es_CL.UTF-8", LC_MONETARY = "es_CL.UTF-8", LC_CTYPE = "en_US.UTF-8", LC_ADDRESS = "es_CL.UTF-8", LC_TELEPHONE = "es_CL.UTF-8", LC_NAME = "es_CL.UTF-8", LC_MEASUREMENT = "es_CL.UTF-8", LC_IDENTIFICATION = "es_CL.UTF-8", LC_NUMERIC = "es_CL.UTF-8", LC_PAPER = "es_CL.UTF-8", LANG = "en_US.UTF-8" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). locale: Cannot set LC_ALL to default locale: No such file or directory
Given it's just a warning, I tend to dismiss it. But when installing some packages, most notably postgres this may cause an issue.
How to solve it
Go to /etc/environment:
sudo vim /etc/environment
Append this the file:
or any other value. I'm in Chile, but I always use everything in English, so I chose en_US,
Then just the reboot the machine
And that's it.
