    What is causing this? There is no indication that something isn't working.
    To which log is the last line referring? We've done massive searches and can't find anywhere it appears.

    Same.... The only error in my update log is the following (note the "E" flag - an easy way to find errors in the log):

    Code:
    [2017-10-18 20:32:02 -0500]   Processing: Restarting any outdated services
[2017-10-18 20:32:02 -0500]    - Processing command `/usr/local/cpanel/scripts/find_outdated_services --always-restart`

    And then, like you, this being reported at the end:

    Code:
    [2017-10-18 20:32:49 -0500] E Post Maintenance ended, however it did not exit cleanly (256). Please check the logs for an indication of what happened
    However, this does not seem to have any ill effects. Perhaps the cPanel folks have some more insight.

    Hi @jndawson

    As ElviCities pointed out, could you check the related log file for the 'E' tag? This can be done as below:
    Code:
    # awk '$4=="E"' /var/cpanel/updatelogs/update.XXXXXX.log
    @ElviCities, The `/scripts/find_outdated_services' script checks for processes/services whose RPM's have been updated, but the service has not been restarted. If you run this script manually, do you see any errors or output?

    Thanks,

    I receive the same error. Rebuilding the RPM database works. If I do an update after that no errors occur, however in the next scheduled update run the error is back.
    The problem started with an upgrade to 68

    Sorry for the delay in responding. Indeed, running the script manually spits out the following error:
    Code:

    Interesting that there is a kernel related error, as nothing on that end has changed.

    It seems that a custom kernel is installed, which blocks this. Is grsecurity in use?

    Yes this is a grs kernel (3.14.32-xxxx-grs-ipv6-64 #7 SMP)

    Hi, yes grsec is in use. Always has been, though. Not sure what has changed on cpanel's end to start causing this.

    Hello,

    I've opened internal case CPANEL-16624 to report the upcp failure notifications in cPanel 68 when the grsec kernel is installed. I'll monitor this case and update this thread with more information as it becomes available.

    Thank you.

    Follow up:

    The 'E' was the clue. We discovered that although each server had the same error, the 'E' line in the log provided different reason for the error. One was a quota issue, another missing vm-tools, etc. Seemed to track down to rpms not getting updated in order, or something.

    Fix was to update rpm database and run upcp --force. Needed to do it twice on at least 2 servers. After that, no further issues.

    Yup, error is different for me as well. RPM solved it for once and the problem came back. I am going to do your suggestion now. update rpm database and run upcp --force twice.

    Hello,

    To update, the resolution for internal case CPANEL-16624 is included in cPanel 68.0.9:

    Fixed case CPANEL-16624: Find_outdated_services: handle grsec kernel more gracefully.

    Thank you.

    Hi incase like me anyone else is searching for "E Post Maintenance ended, however it did not exit cleanly (256)" with the v68 upgrade.

    I also got the error but mine was shown with the E flag

    [2017-11-01 19:47:24 +0000] E [/usr/local/cpanel/scripts/quotacheck] The “/usr/local/cpanel/scripts/quotacheck” command (process 3461) reported error number 255 when it ended.

    I had to increase a users quota, then force the update again, then put the quota back down. Luckily only on one server, but we shouldn't have to do this. Some users keep hitting the quota and won't upgrade so they leave it full.

    In my case, there was an error from the smartcheck command due to there not being an /etc/fstab file, which is normal for a VPS.
    So it could be ignored.

    Here was the issue:

    ========================
    [2017-11-01 13:02:19 -0700] - Processing command `/usr/local/cpanel/scripts/smartcheck`
    [2017-11-01 13:02:20 -0700] E [/usr/local/cpanel/scripts/smartcheck] The “/usr/local/cpanel/scripts/smartcheck” command (process 16541) reported error number 2 when it ended.
    [2017-11-01 13:02:20 -0700] The Administrator will be notified to review this output when this script completes
    ========================

    The smartcheck script failed because there is no /etc/fstab file:

    ========================
    [13:28:35] [8995931] [~]$ stat /etc/fstab
    stat: cannot stat ‘/etc/fstab’: No such file or directory

    Hi @uk01,

    I've moved this to a separate thread:

    upcp failure notification - quotacheck

    Hi @russ@gfx,

    We actually have a separate thread and internal case open for that issue at:

    upcp failure - smartcheck

    I'll update that thread as soon as a resolution is published.

    Thanks!

    @cPanelMichael:

    I've the same problem since the upgrade to version 68 yesterday:
    Code:
    E Pre Maintenance ended, however it did not exit cleanly (256). Please check the logs for an indication of what happened
    However:
    • We're not running a special or customized kernel. Just the standard CentOS one.
    • Running /scripts/find_outdated_services did not find any outdated services.
    Please advise.
