If start new installation with your local language and make cryptography of disk (with english pass)

if start new installation with your local language and make cryptography of disk (with english password) you can’t pass crypto key on start system, cause system has no english locale on start!

And even more – if I choose english locale (and get through crypto) I still get folders (/home/…) named in my language, this is really uncomfortable because u can’t use them in terminal!

I don’t understand the error description. Can you describe the observed behaviour in a more precise way.

You can also run

sudo -E calamares -d

in the terminal and paste the output to a pastebin service.

When you start installation with you local language and make crypto-disk – you face up with the problem with uncryption of the disk, cuz system starts with yours language! And you can’t switch to English!

True.
The password is still what you typed.
the very same keys - just not the same letters …

english keyboard is the default layout

You can remedy it - but only after the fact.
/etc/vconsole.conf

and include it in /etc/mkinitcpio.conf
in the HOOKS or in the FILES

But then: have fun when your native language keyboard might fail to work :smiley:

encryption takes some knowledge …
else you’ll lock yourself out, effectively
