After I restarted my server I got this
$ sudo systemctl restart clickhouse-server.service
$ clickhouse-client
ClickHouse client version 20.4.2.9 (official build).
Connecting to localhost:9000 as user default.
Connected to ClickHouse server version 20.4.2 revision 54434.
As I can see, version of 20.4 is not a stable version. How can I resolve this issue?
