failure to install bash in Zorin-os system

[Jianfeng Menglu]

I am installing Bash into zorin-os system. According to install
instruction, I have successfully passed "configuration", "make' and "make
tests". When I typed "make install", to install, the following message come
up and the installation stopped.

Is there any suggestion to fix this?

Thanks.
