Update of master node 9.0-9.1 fails if there is an additional package in system which contains 'fuel-nailgun' substring

[Vladimir Khlyunev]

If there is more than one package in system that contains "fuel-nailgun" in it (e.g. extensions) "upgrade-prepare master" can fetch wrong package for selecting service for restarting:

=======
[root@nailgun versions]# PACKAGE="$(rpm -qa | grep '^fuel-nailgun')"
[root@nailgun versions]# echo $PACKAGE
fuel-nailgun-9.0.0-1.mos8861.noarch fuel-nailgun-extension-cluster-upgrade-9.1-1.mos81.git.f98dc1c.noarch
[root@nailgun versions]# SERVICES=$(rpm -ql "$PACKAGE" | grep '^/usr/lib/systemd/system/\w*.service$' | awk -F'/' '{print $NF}' | sed 's/.service$//')
[root@nailgun versions]# echo $SERVICES

=======
this leads to not restarted nailgun and non-zero ret code.
Steps to reproduce:
Deploy Fuel 9.0
Install fuel-nailgun-extension-cluster-upgrade package
Upgrade Fuel to 9.1

Workaround: remove fuel-nailgun-extension-cluster-upgrade-9.1-1.mos81.git.f98dc1c.noarch before upgrade.

[Ilya Kharin (akscram)]

This is not a workaround because the fuel-nailgun-extension-cluster-upgrade package is not only one package with such prefix, there is yet one at least.

[Vitaly Sedelnik (vsedelnik)]

Another workaround would be restart nailgun manually. Downgrading to High, adding release-notes tag and retargeting to 9.2.

[Anton Chevychalov (achevychalov)]

Release note.

Update-prepare script unable to restart nailgun services when any of fuel-nailgun extensions was installed on master node.

As workaround it is possible to restart services manually after "update-prepare prepare master" step.

Command to restart:

systemctl restart assassind nailgun oswl_flavor_collectord oswl_image_collectord oswl_keystone_user_collectord oswl_tenant_collectord oswl_vm_collectord oswl_volume_collectord receiverd statsenderd
