8.3.4. Completing Transactions

An unexpected situation, such as power loss or system crash, can prevent you from completing your yum transaction. When such event occurs in the middle of your transaction, you can try to resume it later with the following command as root:
The yum-complete-transaction tool searches for incomplete or aborted yum transactions on a system and attempts to complete them. By default, these transactions are listed in the /var/lib/yum/transaction-all and /var/lib/yum/transaction-done files. If there are more unfinished transactions, yum-complete-transaction attempts to complete the most recent one first.
To clean transaction journal files without attempting to resume the aborted transactions, use the --cleanup-only option:
yum-complete-transaction --cleanup-only
