bitcoin.conf file is missing Just installed bitcoin core v0.21.0 on my ubuntu server.
When I run

bitcoind -printtoconsole

It says bitcoin.conf file is missing.

As I know, it should be in $HOME/.bitcoin folder. But it's not. Should I create it manually?
Yes. It hasn't been created automatically, at least for as long as I remember.
But not in the folder whose screesnhot you've uploaded.
