Some tests are locale dependent

I'm trying to build the project with sbt assembly and I noticed that a couple of tests fail due to different decimal point character.

Forcing locale to English using LC_ALL=C sbt assembly worked. The offending locale should be et_EE.UTF-8.

I've tried setting my location to a few places where I'd expect commas in numerics; brazil, germany but can't reproduce. Where are you, Estonia? Any suggestions how to setup my (dev) machine to replicate?

[Ingramz]

Yes, I am in Estonia. Make sure that locale -a displays the locales you are trying to use. If you don't have a locale installed, then sudo locale-gen et_EE.UTF-8 should do the trick. Otherwise I think it uses the default fallback locale.

[tobyweston]

Is this still an issue?

[Ingramz]

Unsure, I haven't tried in a long time. I'll try a fresh install a bit later.

[Ingramz]

I can confirm that this is still an issue. Below you will find the output of sbt assembly.

Ok thanks, any suggestions on how I replicate? What’s your env? OS?

[Ingramz]

This time I just installed ubuntu 18.04.3 on a VM and selected Estonian as the language, then followed the build from source instructions, installed the required dependencies as needed. But I mean, it should happen with any distro / locale with comma as the decimal separator symbol.
