Highlights in this release

ARC now correctly parses multiple checksums, avoiding download failures that otherwise occured. (Bug 4094)

The following Bugzilla tickets have been addressed or solved

• 4098 0 size job description files being created - and overpopulating controldir

Installing ARC 6

We recommend to install ARC release using the Nordugrid repository.

• Start with the basics
• Get production ready

Note that if you instead install from EPEL for RHEL7 compatible systems, the ARC 6 packages can be found as nordugrid-arc6-* and not nordugrid-arc-*. This was needed in order to supply both ARC 5 already available for RHEL7 and the new ARC 6.

We provide binary builds for all supported versions of:

• Debian (i386 and amd64)
• Fedora (x86_64)
• RHEL/CentOS Linux/CentOS Stream/Rocky Linux (x86_64)
• Ubuntu (LTS and interim releases) on i386 and x86_64 where supported

In addition we build nightly packages for some older platforms.

Contributing

You can submit pull requests to our public repo which mirrors our GitLab repo.

The pull requests will be automatically copied over to our Gitlab repo where they will be merged into the source-code if accepted.
