Hi Everyone, I am using ansible since 2 months. It was working fine uptill now. But, now it is giving error to every ansible command.
For Ex. I am running ping command it is giving following error

ansible -vvvv 172.27.59.27 -m ping

Something is wrong with your "~/.ssh/known_hosts" file?

Hi Giovanni ,
Thanks for your valuable solution. I deleted all entries in known_hosts file and it resolved my issue.

[Daniel]

From the "not_in_host_file" it sounds like possibly something on the ssh side. Are you able to ssh to 172.27.59.27 manually (either with a password or with the certificate that command is trying to use)?

Cheers,

Daniel

A stacktrace is still a bug in our opinion, this PR https://github.com/ansible/ansible/pull/10238 should skip bad data in the file.
