Hello Arunaav, I'm curious if you could double-check the testing environment to make sure the user accounts are as you expected?
chmod 0600 /home/core/.ssh/authorized_keys ssh -i .ssh/id_rsa onprem_shell@10.14.169.25 ssh -v user@10.14.169.25 debug1: identity file /root/.ssh/id_rsa type -1 There's usernames 'core', 'onprem_shell', 'user', and 'root' in play here, and I think it'd be extraordinarily easy to perhaps use sudo or another privilege changing tool in such a way that it is using the wrong private key or the wrong authorized_keys file, etc. Thanks -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2059367 Title: SSH-RSA not supported for Self-SSH in Ubuntu 22.04 FIPS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/2059367/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
