Updating to OSG 25

OSG 25 (the new series) introduces support for EL10. Changes required to upgrade from OSG 24 are relatively minor. Please update all services to OSG 25 as soon as possible.

Updating the OSG Repositories

  1. Consult the relevant section for the service you're upgrading before updating the OSG Yum repositories:

  2. Clean the yum cache:

    root@host # yum clean all --enablerepo=*

  3. Remove the old series Yum repositories:

    root@host # yum erase osg-release

    This step ensures that any local modifications to *.repo files will not prevent installing the new series repositories. Any modified *.repo files should appear under /etc/yum.repos.d/ with the *.rpmsave extension. After installing the new OSG repositories (the next step) you may want to apply any changes made in the *.rpmsave files to the new *.repo files.

  4. Update your Yum repositories to OSG 25

  5. Update software:

    Note

    Because configuration updates will be necessary, be sure to turn off any OSG services before updating them. Consult the sections below that match your situation.

    root@host # yum update

    Warning

    • Please be aware that running yum update may also update other RPMs. You can exclude packages from being updated using the --exclude=[package-name or glob] option for the yum command.
    • Watch the yum update carefully for any messages about a .rpmnew file being created. That means that a configuration file had been edited, and a new default version was to be installed. In that case, RPM does not overwrite the edited configuration file but instead installs the new version with a .rpmnew extension. You will need to merge any edits that have made into the .rpmnew file and then move the merged version into place (that is, without the .rpmnew extension).

  6. Continue on to any update instructions that match the role(s) that the host performs.
