Hello, A few days ago, I asked a question about applying a patch to resolve a problem in my OpenStack environment. I didn't get a response. My question was probably stupid and not appropriate for this list. I apologize. Having to resolve this problem, I searched high and low using search engines. It seems that the solution, with kolla-ansible, is to upgrade to Epoxy, which takes the patch into account. Since this update could cause other problems, I don't want to do it for the moment. Is there another solution? Is it possible to modify the code (it's simply a line to modify in a file (https://review.opendev.org/c/openstack/horizon/+/942946)) in the two Horizon containers in my cluster? I'm really sorry if this is a stupid question, but I've been searching and can't find a method for applying these patches. Franck
