OSG 3.4 End-of-Life Approaching

According to our OSG Software Release Series Support Policy, the OSG 3.4 series is due to reach end-of-life in November 2020. Please upgrade to OSG 3.5 at your earliest convenience.

Summary of changes

This release contains:

  • Frontier Squid 4.11-3.1: Fixed critical bug that causes server errors to be cached indefinitely which may require caches to be cleared. The bug was introduced in version 4.10-3.1
  • VOMS 2.0.14-1.6: Allow VOMS libraries to accept certificates with VOMS attributes that only have a top-level component, such as those provided by the WLCG VO

These JIRA tickets were addressed in this release.


This section describes important upgrade notes and/or caveats for packages available in the OSG release repositories. Detailed changes are below. All of the documentation can be found here.

  • OSG 3.4 contains only 64-bit components.
  • The StashCache service is only supported on EL7

Updating to the new release

Update Repositories

To update to this series, you need to install the current OSG repositories.

Update Software

Once the new repositories are installed, you can update to this new release with:

[email protected] # yum update


  • 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). Watch especially for /etc/lcmaps.db, which every site is expected to edit.
