If that’s not a typo, then it looks like you’re trying to use a very old version of Couchbase that isn’t even supported at the enterprise level anymore. I’m wondering how you even found that packages.couchbase.com link, and it’s possible that’s not even a valid package file anymore (it looks to be suspiciously small).
Is there anything I can do to help you move to a newer version of Couchbase Server?
Just to clarify, that’s the package from here rather than Couchbase Server itself (I think something that old would still be Membase Server! ) If you’re looking to actually download Couchbase Server, check out the Downloads Page.
I just gave this a quick test, and couldn’t reproduce the issue when wgeting the file, nor when using your example of curl -O. I suspect something might’ve gone wrong with the download - does this happen every time you try the steps?
