While updating my CentOS / RHEL HP Linux server via yum command it givens an error which read as follows:


There are unfinished transactions remaining. You might consider running yum-complete-transaction first to finish them

How do I fix this problem under RHEL / CentOS Linux 5.x server operating systems?

You will get this message only if yum finds incomplete or aborted yum transactions on a system.

Run yum-complete-transaction

Type the following command to finish transactions:
# yum-complete-transaction
I recommend running yum-complete-transaction –cleanup-only, which is safe option
# yum-complete-transaction --cleanup-only

The yum-complete-transaction command finds incomplete or aborted yum transactions on a system and attempts to complete them. It looks at the transaction-all and transaction-done files which can normally be found in /var/lib/yum if a yum transaction aborted in the middle of execution. If it finds more than one unfinished transaction it will attempt to complete the most recent one first. You can run it more than once to clean up all unfinished transactions.

    You’re gonna love this. Here’s my response from Red Hat support.

    Thanks for contacting Red Hat support,

    I would like to point you that this is known issue in RHEL 5, we have already escalated this to Engineering Team and they are working on it.

    As per the current update it seems that this issue likely to be fixed in RHEL 5.5 release.
    Well, there is a moral:

    1. Have good backups ( which, thankfully, I do. )
    2. Never use commands you don’t fully understand. ( Even if yum tells you ‘it’s cool’ ).
    3. AVOID AT ALL COSTS yum-complete-transactions!!!!!. It’s a plague on six syllables.

    But, before you can do that command, at least you must install the tool first. Run:

    yum install yum-utils
