Hi @eps1lon,
I see the dynamic part of your cache key is actually referencing two templates: -{{ arch }}-{{ .Revision }}.
The {{ .Revision }} part appears consistent across jobs: 96bfb2c7ac8832896c2ad0bab4d27c96d7c9735e.
Rather, it’s the {{ arch }} part that appears to switch between arch1-linux-amd64-6_85 and arch1-linux-amd64-6_106.
I’m bringing this behaviour to the attention of our engineering teams, and I’ll get back to you.
