Thanks for the follow-up. [...] From there the files were downloadable again.
Nice work!
We are going to try to create a new liberasurecode package 1.6.2 for 20.04 so we can set the environment variable to write legacy CRC headers until all the nodes in the cluster can be upgraded.
I'm not sure if you need a new package, I think you have to set the env at runtime - but there's also a swift config option that will force the env to get set that you can turn off after full upgrade.
This is why we have testing environments.
This is why *competent* deployers and operators have testing environments - and it's the only thing that makes the terrible terrible reality of building and releasing software actually a net good. Couldn't do it without you; go FOSS!
