Good day! In the first steps I have written "yes" after $ssh -p 29418 gerrituser@gerrit.wikimedia.org but then it haven't been continued. So the next time I have had an error like this "debug1: No more authentication methods to try. ...@gerrit.wikimedia.org: Permission denied (publickey)." and I cannot find on your page how this problem may be solved. Two variants mentioned here are not devoted to this case.

@Фәрһад What is your user name for your Wikitech developer account, and which exact complete command did you enter (copy and paste, please)?
user:AKlapper (WMF), in wikipedia and other neighbouring projects my name is written in cyrillic script "Фәрһад". For gerrit it passed not, so I create another account with only latin letters "Faerhad". As it was written here I have made all the steps before this in step "$ssh -p 29418 gerrituser@gerrit.wikimedia.org". it always write "Identity added: .ssh/id_rsa (Фәрһад@F▒rhad)" but the next step don't pass.
@Фәрһад If you are following the Gerrit/Tutorial#Add SSH Private key to use with Git and if you literally entered "ssh -p 29418 gerrituser@gerrit.wikimedia.org" then you did not read the instructions which say "Replace gerrituser by your username".
Edit: Ah, and if you follow https://www.mediawiki.org/wiki/Gerrit/Troubleshooting#%22Permission_denied_(publickey)%22_error then you should replace "username" with your username.
I have found a mistake in previous steps... So now it has been improved. Thanks!
