I am using a fresh install of Unbuntu 20.04 and observe the following error message about
filesystem layer verification failed for digest about almost any image I pull.
root@korra:~# docker pull centos:centos7 centos7: Pulling from library/centos 75f829a71a1c: Verifying Checksum filesystem layer verification failed for digest sha256:75f829a71a1c5277a7abf55495ac8d16759691d980bf1d931795e5eb68a294c0 root@korra:~#
I observed the same behavior yesterday on Fedora32.
I also have a Windows system on the same network, and pulling the same images using Windows system works and I do not see these errors.
Sometimes I see this error, or other certificate related errors:
root@korra:~# docker pull centos:centos7 Error response from daemon: Get https://registry-1.docker.io/v2/: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "Amazon")

Does anybody know what this is about or how to fix it?
