Hi all, We have been testing with 4.0~beta2 in our setup for a few weeks and all has gone very smoothly, however when tried to install 4.0~rc1 we ran into problems with python versions.
We are on Ubuntu 16.04.7 LTS so use apt to install Cassandra, and this now gives the following error: The following packages have unmet dependencies: cassandra : Depends: python3 (>= 3.6) but 3.5.1-3 is to be installed E: Unable to correct problems, you have held broken packages. Looking at the apt packaging the requirement for python has changed from 2.7 to 3.6 between beta4 and rc1. I have found https://issues.apache.org/jira/browse/CASSANDRA-16396 <https://issues.apache.org/jira/browse/CASSANDRA-16396> which says it needed to be python 3.6, however reading this ticket this seems to imply 2.7 is still supported https://issues.apache.org/jira/browse/CASSANDRA-15659 <https://issues.apache.org/jira/browse/CASSANDRA-15659> Also the code for for cqlsh says it supports 2.7 as well: https://github.com/apache/cassandra/blob/b0c50c10dbc443a05662b111a971a65cafa258d5/bin/cqlsh#L65 <https://github.com/apache/cassandra/blob/b0c50c10dbc443a05662b111a971a65cafa258d5/bin/cqlsh#L65> All our clusters are currently on Ubuntu 16.04 which does not come with python 3.6, so this is going to be a major pain to upgrade them to 4.0. Does the apt packaging really need to specify 3.6 ? Thanks Paul Chandler
