From centos 7.9 cannot pull ubuntu images

i’ve a centos 7.9 machine

i am able to pull images e.g. python, debian, … but not the ubuntu

[rootocalhost f]# docker pull ubuntu:latest
Trying to pull repository ... 
manifest for not found
[rootlocalhost f]#

Please, share the outout of the following commands

docker version
docker info

and try to pull the image without the tag:

docker pull ubuntu

But I guess you have probably the same error I explained here:

The Ubuntu images has different manifest format than the python images. Old Docker versions are not compatible with it.
