MongoDB 2.6 Update Error on CentOS using yum

Question

I'm trying to update MongoDB 2.4 to 2.6 on my 64-bit CentOS machine. I have removed the old 10gen repository package and created the /etc/yum.repos.d/mongodb.repo file with the new configuration as explained here .

However, when I run sudo yum install mongodb-org , I get the following error:

Error: mongodb-org conflicts with mongodb-org-server

This is the output in the shell:

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Has anyone else encountered anything similar? What is the best course of action here? Should I try using the --skip-broken option? I did a fresh installation in a new box a couple of days ago and did not encounter any problems.

Thanks for your help with this.

Answer 1

My best guess is that the yum build was broken when they updated to version 2.6.1-0.1.rc0.

For a temporary fix you could:

Try the unstable version, which is currently 2.5.5

yum install mongodb-org-unstable

or the regular mongodb package that comes with OS

yum install -y mongodb mongodb-server

Answer 2

Actually I had the same problem, the process that worked for me was:

1. Stop all mongo processes

    service mongoInstance stop 

2. Remove mongodb

    yum remove -y mongodb 

3. If not removed yet

    rpm -e --noscripts mongodb-server 

After that you may install mongodb-org and re-enable your processes.

Answer 3

Ernie Hershey from MongoDB just answered my post on the MongoDB user group:

https://groups.google.com/forum/#!topic/mongodb-user/5xRQW7ER4hE

Basically, there is a bug in how MongoDB RC packages are generated. So you need to run yum makecache before running yum install mongodb-org . That should fix the problem.

Answer 4

During the release of version 2.6.1-rc0, packages were accidentally published into the MongoDB yum and apt repositories such that new and upgrade requests would install the release candidate 2.6.1-rc0 instead of 2.6.0 (stable release).

Users expecting to install, upgrade to, or retain version 2.6.0 may have inadvertently installed version 2.6.1-rc0, which is a release candidate and not recommended for production use. However, we do not expect that accidentally updating to 2.6.1-rc0 will adversely affect your data or operations.

The packages were incorrectly published on April 22, 5:30pm EDT. The issue was resolved on April 23, 11:30AM EDT. Users who attempted to install or upgrade to version 2.6.0 during this time were affected by this issue.
