Now is Portugal flag, please change it ;D
Edit: Solved, problem was at apt-us language installer.
It's better to report it to the Calamares team, everybody could get in right.
Where this should be done? to the Debian Calamares maintainer Rohan Garg at github?
I used to do that at Calamares GitHub: https://github.com/calamares/calamares/issues
But anyway, I meant the language installer at sparkylinux-aptus....
ooo...
Have a look into that.
Done.
APTus 0.3.17 provides a fix for that.
