Dear list,
I have an issue updating a CentOS 7.9 machine.

A simple "yum update" exists with this error:

# yum update
--> Running transaction check
---> Package kernel.x86_64 0:3.10.0-1160.36.2.el7 will be erased
--> Finished Dependency Resolution
ERROR: update failed. Check the log file for details
Protected multilib versions: libsss_idmap-1.16.5-10.el7_9.11.x86_64 != 
Error: Protected multilib versions: 
libsss_nss_idmap-1.16.5-10.el7_9.11.x86_64 != 

Trying to update excluding all i686 packages reveal the true issue: an 
unmet dependency of

# yum update --exclude="*.i686" libsss_idmap
Resolving Dependencies

---> Package libsss_idmap.x86_64 0:1.16.5-10.el7_9.10 will be updated
--> Processing Dependency: libsss_idmap = 1.16.5-10.el7_9.10 for 
package: sssd-client-1.16.5-10.el7_9.10.x86_64
---> Package libsss_idmap.x86_64 0:1.16.5-10.el7_9.11 will be an update
--> Finished Dependency Resolution
Error: Package: sssd-client-1.16.5-10.el7_9.10.x86_64 (@updates)
            Requires: libsss_idmap = 1.16.5-10.el7_9.10

Basically, yum tries to update libsss_idmap to a too new version, not 
allowed in for sssd-client. I do not use sssd so I can simply uninstall 
the packages, but I am curious about the unmet dependency.

Anyone has the same issue?
