 ## Using sbsigntools
 - first we should compile `sbsigntools`
 ```
-sudo dnf in gcc automake autoconf make binutils-devel gnu-efi gnu-efi-devel help2man # buildrequires on openEuler 22.03
+sudo dnf in gcc automake autoconf make binutils-devel gnu-efi gnu-efi-devel help2man openssl-devel util-linux-devel
+# 根据./configure 提示缺少的文件进行安装 libuuid:util-linux-devel libcrypto:openssl-devel help2man:help2man bfd.h: binutils-devel
+# buildrequires on openEuler 22.03
 git clone https://git.kernel.org/pub/scm/linux/kernel/git/jejb/sbsigntools.git
 cd sbsigntools
 git submodule init && git submodule update
 ./autogen.sh && ./configure && make
+make install # 进行安装
 ```
 - verify the signed EFI image using the certificate we exported
