CentOS 8: How to Update Docker Client

Question

I previously installed docker in my CentOS 8, and now I was trying to update.

My steps to update were described in this answer https://stackoverflow.com/a/67942165/1410223

sudo rpm -Uvh https://download.docker.com/linux/centos/8/x86_64/stable/Packages/containerd.io-1.4.6-3.1.el8.x86_64.rpm
sudo rpm -Uvh https://download.docker.com/linux/centos/8/x86_64/stable/Packages/docker-ce-cli-20.10.7-3.el8.x86_64.rpm
sudo rpm -Uvh https://download.docker.com/linux/centos/8/x86_64/stable/Packages/docker-ce-20.10.7-3.el8.x86_64.rpm

But checking my version...

Alternatively

How to update the client?

MY STEPS

$ rpm -qa | grep containerd
containerd.io-1.4.6-3.1.el8.x86_64
$

I try to uninstall

$ rpm -evh containerd
error: package containerd is not installed
$

Let's try again

$ rpm -evh containerd.io-1.4.6-3.1.el8.x86_64
error: Failed dependencies:
    containerd.io >= 1.4.1 is needed by (installed) docker-ce-3:20.10.7-3.el8.x86_64
$

Let's check docker-ce.

$ rpm -qa | grep docker-ce
docker-ce-cli-20.10.7-3.el8.x86_64
docker-ce-rootless-extras-20.10.7-3.el8.x86_64
docker-ce-20.10.7-3.el8.x86_64
$

Go for remove it

$ rpm -evh docker-ce-20.10.7-3.el8.x86_64
error: Failed dependencies:
    docker-ce is needed by (installed) docker-ce-rootless-extras-0:20.10.7-3.el8.x86_64
$

Then

$ rpm -evh docker-ce-rootless-extras-0:20.10.7-3.el8.x86_64
error: Failed dependencies:
    docker-ce-rootless-extras is needed by (installed) docker-ce-3:20.10.7-3.el8.x86_64
$

Try again remove both: docker-ce and docker-ce-rootless-extras!

$ sudo rpm -evh docker-ce-20.10.7-3.el8.x86_64 docker-ce-rootless-extras-0:20.10.7-3.el8.x86_64

Unfortunately I have the same version Client!

Using a search tool that inspects the files inside and looking for which files have the 19.03.12 version of docker to uninstall.

Many files were found with the content "19.03.12", but the most suspicious were on $HOME/bin directory:

docker
dockerd

I found some files on

$ ls ~/bin
containerd  containerd-shim  ctr  docker  dockerd  dockerd-rootless.sh  docker-init  docker-proxy  rootlesskit  rootlesskit-docker-proxy  runc  vpnkit
$

Maybe just deleting or renaming those files would have been enough (without having to uninstall or reinstall everything), but I didn't test at the time.

I uninstall all again:

$ sudo rpm -evh \
containerd.io-1.4.6-3.1.el8.x86_64 \
docker-ce-20.10.7-3.el8.x86_64 \
docker-ce-rootless-extras-0:20.10.7-3.el8.x86_64 \
docker-ce-cli-20.10.7-3.el8.x86_64 \
docker-scan-plugin-0.8.0-3.el8.x86_64

I renamed the suspicious files (I renamed almost all of them, although some could be unnecessarily).

$ ls $HOME/bin
containerd_OLD  containerd-shim_OLD  ctr  dockerd_OLD  dockerd-rootless.sh_OLD  docker-init_OLD  docker_OLD  docker-proxy_OLD  rootlesskit-docker-proxy_OLD  rootlesskit_OLD  runc_OLD  vpnkit
$

Install all again

$ sudo rpm -Uvh \
