How to remove offending key in git when you try to push your changes?

  • 772

I've done tons of search and tested different solutions, but gain no success!

When I want to push my codes, I receive the following error: 

Warning: the ECDSA host key for 'git.mywebsite.ir' differs from the key for the IP address '164.138.23.11'
Offending key for IP in /home/alireza/.ssh/known_hosts:10
Matching host key in /home/alireza/.ssh/known_hosts:1
Are you sure you want to continue connecting (yes/no)? yes

What should I do to remove this message every time I push my changes? Any idea?

key list

ssh

    It says:

    Offending key for IP in /home/alireza/.ssh/known_hosts:10

    So for some reason you have to delete 10-th line in known_hosts.

    Run this command to delete 10-th line in known_hosts:

    sed -i '10d' ~/.ssh/known_hosts

    Or use ssh-keygen

    ssh-keygen -R git.mywebsite.ir

    Quote from man

     -R hostname
         Removes all keys belonging to hostname from a known_hosts file.
         This option is useful to delete hashed hosts (see the -H option
         above).

  2. When I got the messages:

    Offending key for IP in /home/myusername/.ssh/known_hosts:12

    Notice the line number - in my case - 12

    So open 'known_hosts' file and delete the 12-th row.

    For me this solved the problem.

    P.s. Notice if you cannot find the .ssh folder - the .ssh folder is hidden and in order to see it from the file manager - you have to "Show hidden files and folders". In Linux Mint (and possible in your distro too) when in the file manager - there is a shortcut to show/hide hidden folders -> Ctrl+H

    Cheers

  3. You have to edit your known_hosts file (located in ~/.ssh/known_hosts) and remove an entry asociated with this address.
