I have just upgraded our ipa-server from 4.2 to 4.6.4 via yum update on OEL 7.2.
At the very last step of the yum update I got the following warning:
OSError: No such file or directory
ValueError: SELinux policy is not managed or store cannot be accessed.
warning: %posttrans(bind-32:9.9.4-72.el7.x86_64) scriptlet failed, exit status 1
Non-fatal POSTTRANS scriptlet failure in rpm package 32:bind-9.9.4-72.el7.x86_64
The update process hung at this point. Pressing CTRL C,  produced:
warning: %posttrans(ipa-server-4.6.4-10.0.1.el7.x86_64) scriptlet failed, signal 2
Non-fatal POSTTRANS scriptlet failure in rpm package ipa-server-4.6.4-10.0.1.el7.x86_64
Can I ignore this warning? My initial tests indicate that the upgrade was a success:
* I can log into IPA clients.
* I can log into JIRA (authentication via IPA LDAP integration)
* SSL RC4 no longer supported on port 443 (this was the main reason for the upgrade)
* Samba initially failed (smb running on the same server as ipa-server), but after upgrading Samba from 4.4.4 to 4.8.3 now works.
