Ubuntu 1804 - Default 'locale' setting results in portability issues because response to prompts are required to be UPPER case only!

[mi-hol]

Windows build number: Microsoft Windows [Version 10.0.17134.228]
with Ubuntu 1804 distribution and Windows host set to 'culture' German (Germany) but Windows UI language = English(US)

Get-Culture

LCID             Name             DisplayName
----             ----             -----------
1031             de-DE            German (Germany)

• What you're doing and what's happening:
  PowerShell commands requiring a confirmation only accept UPPER case response

• What's wrong / what should be happening instead:
  confirmations are case insensitive.
  This has the impact of case in-sensitive powershell scripts suddenly being CASE sensitive for prompts. Meaning portability is lost!

• Steps required to reproduce

1. install Ubuntu 1804
   =>results in a strange locale 'en-US-POSIX' that I was unable to change!

2. install powershell-preview RC1 according to:
   https://docs.microsoft.com/en-us/powershell/scripting/setup/installing-powershell-core-on-linux?view=powershell-6#ubuntu-1804

# Import the public repository GPG keys
curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -

# Register the Microsoft Ubuntu repository
sudo curl -o /etc/apt/sources.list.d/microsoft.list https://packages.microsoft.com/config/ubuntu/18.04/prod.list

# Update the list of products
sudo apt-get update

# Install PowerShell
sudo apt-get install -y powershell-preview

# Start PowerShell
pwsh-preview
Get-Culture
Set-Content foo.txt -Value "hi" ; $ConfirmPreference="low"; Remove-Item foo.txt

Confirmation that standard Ubuntu 18.04 in a VM doesn't show this issue
PowerShell/PowerShell#7639
due to a different LCID.
Also issue does NOT appear in Ubuntu 1704!
I failed to set a different locale due to error

sudo localectl
Failed to create bus connection: No such file or directory

could be related to #3018

could be related to #3018

Probably not directly unless WSLENV is in play somehow here, which I don't think it is. The problem over there is a pretty specific bad interaction.

sudo localectl

That isn't going to work because no systemd

install Ubuntu 1804
=>results in a strange locale 'en-US-POSIX' that I was unable to change!

No need to yell.

$ sudo locale-gen de_DE.UTF-8
$ sudo update-locale LANG=de_DE.UTF-8

Notably enough, whatever behavior PowerShell exhibiting with en-US-POSIX (assuming it is even incorrect behavior) is going to be the same on Real Linux

Thanks @therealkenc
Good to have a workaround but what really concerns me is the different behavior of WSL Ubuntu1704 and WSL Ubuntu1804 in this matter.

PS: not sure to understand your comment 'No need to yell.'

but what really concerns me is the different behavior of WSL Ubuntu1704 and WSL Ubuntu1804 in this matter.

The launcher changed between 16.04 and 18.04 may be the cause of this (analogous to but different than #3273). There is no difference in WSL behavior, and WSL does not control Ubuntu behavior.

Ausrufezeichen übersetzt schlecht

[mi-hol]

Symbolische Bedeutungen aus https://de.wikipedia.org/wiki/Ausrufezeichen
Das Ausrufezeichen steht allgemein für ‚wichtig‘, insbesondere für eine Warnung (‚Achtung‘), oder für ‚Gefahr‘ und ‚Gefährdung‘.
Achtung vor Gefahr! (Straßenverkehr, international üblich)

That road sign translates badly too. I changed my locale to en_CA and all I got was:
