Michael Kelly commented on CASSANDRA-16605:
-------------------------------------------
Not quite.
If python3 is not supported until Cassandra 4.0, that's fine by me.
The issue is that cassandra3 has a dependency on 'python >= 2.7'.
In Ubuntu 20.04 (and later, I presume), no package can satisfy that dependency
(the 'python' package was removed sometime after 18.04).
The python2 package provides 'python2=2.7.17'.
I guess the optimal solution would be to change the dependency list, something
like:
Depends: python (>= 2.7) | python2 (>= 2.7), ...
That should cover all currently supported versions of Ubuntu.
> The dependencies in the Cassandra DEB package prevent installation on Ubuntu
> 20.04+

>
> The DEB package for Cassandra has a dependency on 'python >= 2.7'.
> In Ubuntu 18.04 there is a package called 'python' which installs python2.7.
> This package has been removed in Ubuntu 20.04 so the dependency cannot be
> satisified.
>
> Proposed solution:
> Change the dependency 'python >= 2.7' to something like 'python2 >= 2.7 OR
> python3 >= 3.6'.
