[9.2][updates] contrail5.0.1 plugin's packages couldn't be installed from the plugin repository

[vnaumov]

Fuel 9.0 -> 9.1 -> 9.2, Contrail 5.0.0(updated to 5.0.1), LDAP 3.0.1 [1]

Steps to reproduce:
  1. Deploy 9.0 env + contrail plugin (9 slaves) [2]
  2. Install and configure LDAP
  3. Reset env (to activate ldap)
  4. Deploy changes
  5. Update to 9.1 state master node [3]
  6. Add mos-updates
"deb http://mirror.fuel-infra.org/mos-repos/ubuntu/9.0/ mos9.0-updates main restricted"
     into Settings -> General on Fuel UI
  7. Run `fuel2 update --env {env_id} install --repos mos-updates --restart-rabbit --restart-mysql` on master Node
  8. Deploy changes
  9. scp contrail-5.0-5.0.1-1-5.noarch.rpm root@10.109.0.2:/tmp
  10. fuel plugins --update /tmp/contrail-5.0-5.0.1-1-5.noarch.rpm (as a workaround to bug [4])
  11. start update to 9.2 [5]
  12. cd /etc/yum.repos.d/
  13.vim mos92-updates.repo
  14.switch update mechanism in repo-url to snapshots-case, and use MOS_CENTOS_PROPOSED_MIRROR_ID=proposed-2017-01-28-114420 from snap 822 (rc2)
  15. continue updating to 9.2 [6]
  16.replace step 4 in above guide by following command
ansible-playbook playbooks/mos9_prepare_env.yml -e '
{"env_id":1, "snapshot_repo":"snapshots/9.0-2017-01-28-114420", "snapshot_suite":"mos9.0-proposed" }'
  17.check that's above snap-repo matched with repo-mos-updates in fuel UI
  18. go to step 9(from guide), fuel2 update --env 1 install --repos mos9.2-updates
  20. failed to deploy
  21. redeploy with disabled Security TLS(as a workaround to [8])
  22. step 10 from guide (upgrade kernels)
  23. restart all nodes (using ansible)
  24. check kernel-versions on nodes

Expected results:
successful deploy and continue updating env

Actual result:
in fuel UI there was deploy changes button and when you push it, deploy failed on task

[Ruslan Khozinov (rkhozinov)]

I've investigated the issue and I've found the root cause - it's an empty Packages.gz file for
http://10.109.0.2:8080/plugins/contrail-5.0/repositories/ubuntu/

in /var/www/nailgun/plugins/contrail-5.0/repositories/ubuntu/Packages.gz

It seems, like the step:
 dpkg-scanpackages . /dev/null | gzip -9c > Packages.gz

was missed by puppet manifests

[Ruslan Khozinov (rkhozinov)]

@ipolliul Should we execute install.sh script during update the contrail plugins from 5.0.0 up to 5.0.1 ?

[Illia Polliul (ipolliul)]

Yes, looks like upgrading plugin rewrites Packages.gz, so need to add step with running install.sh after plugin upgrade.
