Brandon Williams commented on CASSANDRA-15889:
----------------------------------------------

Sorry, I missed this too.  I've opened/tagged the ticket appropriately to 
prevent this from slipping through.

bq. I am curious how [arch=amd64] doesn't break it for any debian distribution 
and architecture, like i386. But debian package management foo is weak here.

Well, actually, i386 is the other option we publish:

https://dl.bintray.com/apache/cassandra/dists/40x/main/

If you dig into either of those or our packaging though, the architecture is 
'all' so this is not an issue of packaging, but whatever is managing our Debian 
repository is only publishing the package list for amd64 and i386 
architectures.  Anyway, we should fix this to include arm64, rather than 
specifying an architecture in our docs, since while that will work, it is 
horrible system hygiene.

Mick, is your foo any stronger with what is building  the repo? :)

> Package cassandra is not available, but is referred to by another package.
> This may mean that the package is missing, has been obsoleted, or
> is only available from another source
> E: Package 'cassandra' has no installation candidate
> {code}
> Note that there is a workaround available: if you specify "amd64" as the arch 
> for the source, it downloads and runs on Arm without issue:
> {code:bash}
> echo "deb [arch=amd64] https://downloads.apache.org/cassandra/debian 311x 
> main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list
> {code}
> The Redhat RPM contains a "noarch" arch type, so it will download on any 
> host. (Cassandra does not use separate binaries/releases for different 
> architectures, so this seems to be the correct approach, but adding an 
> aarch64 variant would also suffice.)
