rpm -qa | grep selinux-policy
selinux-policy-38.28-1.fc38.noarch
selinux-policy-minimum-38.28-1.fc38.noarch
selinux-policy-devel-38.28-1.fc38.noarch
selinux-policy-doc-38.28-1.fc38.noarch
selinux-policy-targeted-38.28-1.fc38.noarch

I wanted to see other packages, too. Maybe also

semodule -lfull | grep -v ^100

 

Noticed one machine that gets failed didn't have selinux-policy-doc
installed and installed it, then tried reinstalling all the
selinux-policy and still got error?
Failed to resolve allow statement at
/var/lib/selinux/targeted/tmp/modules/200/container/cil:1186
Failed to resolve AST
/usr/sbin/semodule:  Failed!
Files in that directory are
-rw-------. 1 root root     2 Sep 21 08:09 lang_ext
-rw-------. 1 root root 24411 Sep 21 08:09 hll
-rw-------. 1 root root 13487 Sep 21 08:09 cil

The cil file is a binary file, so not sure what :1186 means?
that tmp directory doesn't exist on my notebook that doesn't have
error?

It's a temporary directory used for the policy rebuild. Try this:

f39# file /var/lib/selinux/targeted/active/modules/200/container/cil
/var/lib/selinux/targeted/active/modules/200/container/cil: bzip2 compressed data, block size = 500k
f39# file -z /var/lib/selinux/targeted/active/modules/200/container/cil
/var/lib/selinux/targeted/active/modules/200/container/cil: ASCII text, with very long lines (446) (bzip2 compressed data, block size = 500k)
f39# bunzip2 </var/lib/selinux/targeted/active/modules/200/container/cil | sed -n '1180,1187p'

What's in the output?

set selinux to minimal on machines.

Don't understand this.
