The invalid locale error came from the install layout: when the installation directory is a symlink, postinstall.sh skips the step that rewrites substrings in files to point at the actual install path, so the locale files never get fixed up. The fix is to not install through a symlink, or to re-run the corrected postinstall.sh. The maintainer merged the script fix in commit 18bd3da and it shipped in the next patch release, and the reporter confirmed it worked. Source: https://github.com/yugabyte/yugabyte-db/issues/3732
