The root cause of your problem seems to be an installation of "suroegin's package - sort" which apparently is incompatible with Ubuntu - or even more, or even worse, seems to be a broken nonsense package.

(Note: the quote inside the quoted string would have to be escaped)

I suggest that you remove that package.

What a mess. You aren't adding PPAs correctly and missing the keys. Hence the warnings.

You can make that better with:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys D800C7D66F036044

Repeat for each missing key above in your output. This will help some.

Also run:

sudo rm /etc/apt/sources.list.d/google.list

If you now run:

sudo apt-get update

Is it smooth?

I see several different problems on your system.

1. You have got a processor based an amd64 architecture, and this processor can also run i386-architecture programs. This is correctly reflected in the settings of the dpkg package management program.
For reasons unknown to me you have also activated that dpkg searches for packages with arm64 architecture. You have, however, not correctly set up your package management system for that, as this needs references to a specific "ports" server. The "normal" Ubuntu repositories (like kr.archive.ubuntu.com) do not contain the packages for arm64 architecture.

Do you really need the packages for arm64?
If yes, then you have to restructure the contents of the sources.list configuration file to look for the arm64 packages on the ports.ubuntu.com server.
If no, then you should remove the definition of arm64 as accepted architecture in dpkg.

2. You seem to be missing the signature keys for
file:/var/cuda-repo-9-0-local
file:/var/visionworks-repo
file:/var/visionworks-sfm-repo
file:/var/visionworks-tracking-repo
Which instructions did you follow to install these repositories?
Did you follow these instructions completely?

On https://samuel.netlify.com/post/install-cuda-on-ubuntu-16-04/ I see an instruction
sudo apt-key add /var/cuda-repo-9-0-local/7fa2af80.pub

I follow this video https://www.youtube.com/watch?v=D7lkth34rgM&t=461s for these:
file:/var/cuda-repo-9-0-local
file:/var/visionworks-repo
file:/var/visionworks-sfm-repo
file:/var/visionworks-tracking-repo

for http://security.ubuntu.com/ubuntu/dists/xenial-security/main/binary-arm64/Packages I would like to remove it completely, please help me by safe method. I tred used this method but I can't http://ask.xmodulo.com/find-remove-obsolete-ppa-repositories-ubuntu.html

finally, you mention above that I used them without key, please let me know how to know thier keys.

For removing the references to the arm64 architecture execute the command
sudo dpkg --remove-architecture arm64

Have you tried running the command
sudo apt-key add /var/cuda-repo-9-0-local/7fa2af80.pub
Does it work, or does it give error messages?

What is now the output of
sudo apt update

I choose the system is 64-bit, why do you want that I remove it?

Don't confuse amd64 and arm64!
amd64 is the 64-bit version of Intel/AMD processors (based on x86 architecture)
arm64 is for a completely different type of CPUs, based on a reduced instruction set (RISC), e.g. those in smartphones.

What is the output of the commands

dpkg --get-selections | awk '/arm64/{print $1}'

What exactly is your aim?
Do you want to do cross compilation on your Ubuntu system for a different system that has an arm processor?
Only in that case you need the arm packages.

I suggest that you execute the following commands:

sudo apt purge cuda-cublas-cross-aarch64-9-0:arm64 cuda-cudart-cross-aarch64-9-0:arm64 cuda-cufft-cross-aarch64-9-0:arm64 cuda-curand-cross-aarch64-9-0:arm64 cuda-cusolver-cross-aarch64-9-0:arm64 cuda-cusparse-cross-aarch64-9-0:arm64 cuda-driver-cross-aarch64-9-0:arm64 cuda-misc-headers-cross-aarch64-9-0:arm64 cuda-npp-cross-aarch64-9-0:arm64 cuda-nvgraph-cross-aarch64-9-0:arm64 cuda-nvml-cross-aarch64-9-0:arm64 cuda-nvrtc-cross-aarch64-9-0:arm64

sudo dpkg --remove-architecture arm64

If you then run the command
sudo apt update
what output do you receive?
