Are you stuck with two Git repositories or branches that have completely different histories, but you need to merge them? You may be hitting a roadblock because Git is designed to prevent this kind of operation by default. However, there’s a workaround for this, and it’s simpler than you might think.

The Problem: Unrelated Git Histories#

Imagine you’re working on a project where you have a main branch, and someone else has a completely separate project with its own history. Now, you want to combine both projects into a single repository. If you try to perform a regular git merge or git rebase, Git will likely stop you with an error message, something like:

How to Solve the Puppet Error: Could not find class in namespace#

Sometimes, when working with Puppet, you may encounter an error message that does not accurately reflect the actual problem. For example, if you see this error:

err: Could not retrieve catalogue: Could not find class php in namespaces standardbuild at /etc/puppet/manifests/templates.pp:15 on domain.internal.com

One of the possible causes could be a missing curly bracket in your code. This can be hard to spot and can waste a lot of your time. To avoid this, make sure you check your syntax carefully and use a code editor that can highlight any errors for you.
