Why Does a Linux Service Fail When the System Locale Changes?

A locale change can affect date parsing, sorting, decimal separators, character handling, and command output. Scripts may behave differently even when the same files and software are present.

What to check

Check service environment variables, system and user locale, application logs, date and number parsing, and whether scheduled jobs inherit the same environment. Reproduce with representative input data.

Recommended next step

Set an explicit supported locale for the service and test data handling across expected languages and formats. Avoid relying on an administrator’s interactive shell locale for production behavior.
