Just for the record, the same problem will occur in rhel 8. Both both of 'try-reload-or-restart' and 'reload-or-try-restart' will exit non-zero if the service provided is not present. For the record, as we already agreed on IRC on that, this is a very specific corner case as RHEL is always shipped with NetworkManager. The chance of having a customer running into this problem if very unlikely. This won't be fixed for RHEL-7.9 but I'll add as a lower priority for RHEL-8. Thanks for reporting that! Just experienced this same problem when updating to CentOS 7.9.2009 on a Hetzner Cloud Server. This is not really a "specific corner case", IMHO :-) (In reply to Joerg Lehmann from comment #4) > Just experienced this same problem when updating to CentOS 7.9.2009 on a > Hetzner Cloud Server. This is not really a "specific corner case", IMHO :-) Sure we can reopen this BZ in this case. As you mentioned on BZ#1829713, you do have NM installed and you're still facing this issue. Can you post the logs? I do not have NM installed. This explains the error, not sure why there is no RPM-dependency to NM if it is required though. It's not a big deal, but to have failed services after a normal update is just not so nice. (In reply to Joerg Lehmann from comment #7) > I do not have NM installed.

Agreed. I'll raise the priority on this one and will fix on the coming week. Thanks for sharing the bug!

FYI: CentOS-7-x86_64-GenericCloud-yymm.qcow2 images have been shifted without NetworkManager. There are hundreds of such VMs in the cloud infrastructure, and suddenly after upgrading from 7.x to 7.9, somebody decided to add dependency for NM, which was not present all the time. Does not sound fair Also impacted by this issue. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Created attachment 1729145 [details] Proposed fix for issue. Description of problem: cloud-final.service wil fail if NetworkManager is not installed. journal -u cloud-final.service would show: cloud-init[5328]: Cloud-init v. 19.4 finished at ... echo[5346]: try restart NetworkManager.service systemctl[5349]: Failed to reload-or-try-restart NetworkManager.service: Unit not found. systemd[1]: cloud-final.service: control process exited, code=exited status=5 systemd[1]: Failed to start Execute cloud user/final scripts. systemd[1]: Unit cloud-final.service entered failed state. systemd[1]: cloud-final.service failed. Note that both of 'try-reload-or-restart' and 'reload-or-try-restart' will fail if the service is not present. So this would also affect rhel 8 systems that do not use NetworkManager. Version-Release number of selected component (if applicable): cloud-init-19.4-7.el7_7 How reproducible: Always
