Description

Based on default yum behaviour, even though incomplete transaction causes any delay in installing packages, yum internally performs cleanup and then proceeds with installation of on-going packages.

However, our code prevents default yum behavior and fails to perform installation of packages.

- - Identify the pending transactions with the command 'yum history list <packages failed>'
2018-10-05 13:47:09,975 - - Revert each pending transaction with the command 'yum history undo'
- - Flush the transaction log with 'yum-complete-transaction --cleanup-only'
- 
Traceback (most recent call last):

    InstallPackages().execute()

    raise Fail("Failed to distribute repositories/install packages")
resource_management.core.exceptions.Fail: Failed to distribute repositories/install packages

 

With the changes submitted in PR, we have not found any issues with yum installation of packages for the first time or multiple times on the same host for upgrade. Even though agent kills yum, yum internally takes care of completing the transaction itself.
