Install FPBX 14: change language

Hey Guys,

I try installing the Beta with 14/14 as combo on a VM (OMV-Virtualbox)

But when ever I have my VM HDD big enough (4GB or more) the install goes all the way w/o me beeing able to change the locale… and I hate the US layout on my DE keyboard in the console. This is also a problem with suitable passwords for root…

So how do I interupt the automated install process? I tried STRG+C but it wont work…, to change the language / locale settings.

I did try to yum update and localectl set LANG=de_DE.utf8, but it ends with lots of file not found things. (of course I did check that de_DE.utf8 is availabe)

Regards
Manne
