Upgrade from CentOS 4 to CentOS 5…


I upgraded my main server at home from CentOS 4 to CentOS 5 last night. The upgrade from the installation DVD went OK, but when the upgrade was complete and I tried to check for software updates on the net using “yum update”, it complained about a number of package conflicts. On closer inspection I found that about 10 old packages were still present on the server, causing conflicts with newer versions. I removed the old packages and the software updater ran fine.

Now CentOS 5 is up and running, I guess I need to see what else I’ve broken along the way. I wonder how long it will be before I switch off the transparent windows and wobbly menus? 🙂

As is always the case, it’s better to do a clean OS install rather than an upgrade, but I really couldn’t be bothered. Maybe in a few weeks I’ll blow it away and start again.

  1. You should have done a little more of Googling before upgrading.

    And as far as I can see it with YUM, try #yum clean – I suppose it gets rid of all that oldies.

    Also, instead of #yum update, try #yum upgrade 😉

  2. Hi.

    I did the upgrade itself using the CD media, not yum. The yum stuff was only for the updates, post CD release. I guess the “clean” would have helped. 🙂
