I tried to use AWS system manager to scan whether my Ubuntu EC2 is missing any patches. After I "Run a Command" using AWS-RunPatchBaseline, it showed that thr PatchLinux scan failed. The error message is shown below.
Does anybody know what is the reason and how to fix/debug it?
My EC2 to be patched is: ubuntu 16.04.

Update: in fact I clicked "Run a command" again, but this time I saved the complete output to S3, now I saw more error message, it seems the reason is: aws try to install python3-apt in my EC2 and fail.
in fact, I ssh to this ec2 and manually run:
sudo apt-get update
and then:
sudo apt-get -y upgrade
and it showed this error:

I believe if I can figure out how to run "sudo apt-get -y upgrade" successfully, then the original issue of scan will be resolved. anybody know how to fix the issue when I manually execute "sudo apt-get -y upgrade"?
