OpenSSH 8.3p1 introduces the need of having a public SSH key otherwise is gonna show the warning
load pubkey "/root/.ssh/id_rsa": invalid format
# ssh -V
OpenSSH_8.3p1, OpenSSL 1.1.1g 21 Apr 2020To supress this message we can put in place our SSH public key or generate it from our private key with:
# ssh-keygen -y -f /root/.ssh/id_rsa > /root/.ssh/id_rsa.pubAs pointed out in https://bbs.archlinux.org/viewtopic.php?id=256210 there is already a commit ready to fix this in the future.
I am getting this warning in OpenSSH_7.9p1. I have both private and public keys in the same place. Any Idea, what to do?
That message should be for version 8.3p1, anyway, I would check permissions. OpenSSH is very sensible to them.
For me it was due to newer private key format, which generates:
-----BEGIN OPENSSH PRIVATE KEY-----
...
To fix this, I have regenerated file using -m pem option:
ssh-keygen -t rsa -b 4096 -m pem

Your solution worked for me precisely. Thanks.
Didn't work for me :(

Maybe you're using UTF8-bom. You can use sed -i 's/^\xEF\xBB\xBF//g' /root/.ssh/id_rsa to remove bom in the rsa file.

i ve had exactle the same error.
Load key "key_name": invalid format
I have solved it.
I suggest to check two things:
if you are using ~/.ssh/config
then pls check that you have specified there you PRIVATE key. If you specified publick key there - you ll get the error
pls check your echo $HOME.
in some OS like ubuntu\debian when you type:
$ sudo bash
your $HOME directory stay the same. I mean it is not /root
so OS is looking for ssh keys in /home/user/.ssh/ dir!
But you think it is using /root/.ssh dir
so pls check echo $HOME.
