Building an Image from file error

hi to all,

I am new to Docker world. First time I am trying to create an image with docker file it is giving the error message as bellow.

Below is the details of Docker file from which I am building the image.

FROM ubuntu
RUN apt-get update
RUN apt-get upgrade -y
RUN apt install -y openssh-server vim
RUN mkdir /var/run/sshd
RUN echo ‘root:AbC-123#’ |chpasswd
RUN sed -i ‘s/#PermitRootLogin prohibit-password/PermitRootLogin yes/’ /etc/ssh/sshd_config
RUN sed ‘s@session\srequired\ optional’ -i /etc/pam.d/sshd
ENV NOTVISIBLE “in Users profile”
RUN echo “export VISIBLE=now” >> /ect/profile

#to enable the any service to start at containers startup

CMD ["/usr/sbin/sshd", “-D”]

Bellow is the output of build command.

The command ‘/bin/sh -c sudo echo “export VISIBLE=now” >> /ect/profile’ returned a non-zero code: 127

that’s the output of command. Google is not helping in this. Any help would be highly appreciable.
Thanks in Advance.
