81f9f8b4cbe170e6b6=0A=0AI decided to test it, but unfortunately I get "Too =

t this error is and how to fix=0Ait? I did not find any useful information =
on the web.=0AThe problem is not related to efi file size.=0A=0AI usually u=
se a third-party implementation from here=0Ahttps://aur.archlinux.org/packa=

orks fine, but when you added the=0Aimplementation of Argon2 this version a=
lso can not be builded from the source=0Abecause of the patch conflict.=0A=
