Steps to reproduce:
swarm https://product-ci.infra.mirantis.net/job/9.x.system_test.ubuntu.system_test.deploy_centos_master/3/console
Expected results:

Actual result:
Test cannot not manipulate with package
Reproducibility:
100%

The possible root cause of issue is missed PRE-script. Here is configuration of the similar job in previous 9.0 branch with example of shell script executed before test/ https://jenkins-sandbox.infra.mirantis.net/job/9.0.system_test.ubuntu.system_test.deploy_centos_master/configure

looks like pre-script option is missing in new 9.x system test template
