ClickHouse Upgrade

If ClickHouse was installed from deb packages, execute the following commands on the server:

$ sudo apt-get update
$ sudo apt-get install clickhouse-client clickhouse-server
$ sudo service clickhouse-server restart

If you installed ClickHouse using something other than the recommended deb packages, use the appropriate update method.
