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.
ClickHouse does not support a distributed update. The operation should be performed consecutively on each separate server. Do not update all the servers on a cluster simultaneously, or the cluster will be unavailable for some time.
