docker install container-selinux hang on centos

Question

i have centos 7 (on Xen) and I'm trying to install the latest stable update. first thing that I did is to stop the docker service and remove old versions from the procedure

then I have tried to install docker-ce using the command (I have already added the docker repo):

sudo yum install docker-ce

from some reason the installation hang.

command output:

Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: repo1.ash.innoscale.net * epel: mirror.us.leaseweb.net * extras: mirror.rackspace.com * updates: ftp.osuosl.org Resolving Dependencies There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help). --> Running transaction check ---> Package docker-ce.x86_64 0:17.09.0.ce-1.el7.centos will be installed --> Processing Dependency: container-selinux >= 2.9 for package: docker-ce-17.09.0.ce-1.el7.centos.x86_64 --> Running transaction check ---> Package container-selinux.noarch 2:2.28-1.git85ce147.el7 will be installed --> Finished Dependency Resolution

the installation hang on container-selinux. after stopping (I have waited 1 hour) the yum install process I'm getting the error:

warning: %post(container-selinux-2:2.28-1.git85ce147.el7.noarch) scriptlet failed, signal 2 Non-fatal POSTIN scriptlet failure in rpm package 2:container-selinux-2.28-1.git85ce147.el7.noarch

now here is the strange thing... actually after stopping the process the container-selinux has been installed (not sure if successfully) so after that I was able to install docker-ce without issue but only after interrupt the fist installation that was hang

any idea how to complete the installation without the be hanging?

remarks:

1) already tried reboot

2) already tried to install using the command: yum install --setopt=obsoletes=0 docker-ce

3) the repository extras already enabled

4) no disk space or performance issue on the server

5) already tried: yum-complete-transaction --cleanup-only

6) there is already containers + volumes that their data (under /var/lib/docker/) is still exist on disk

Answer 1

after several hours of trying things to make the installation work without hanging I have succeeded only after yum update all the packages in the server

looks like that the package (in my case) container-selinux-2.28-1.git85ce147.el7.noarch.rpm (here) contains some Requirements of the packages (here):

libselinux-utils
policycoreutils >= 2.5-11
policycoreutils-python
selinux-policy >= 3.13.1-39
selinux-policy-base >= 3.13.1-39
selinux-policy-targeted >= 3.13.1-39

I didn't try to update only them but probably it will do the work
