I have Oracle Linux 8.5 in Oracle Cloud, and have been using the host for several months.

But today I was trying to setup vscode remote ssh and looks like I messed up the ssh key that I use to login to the host. Now I cannot!

I tried to follow this documentation and this thread to fix some commands.

However, that did not help! And in fact now the host having difficulty stopping quickly; rebooting looks fine.

Any ideas on how to correct this issue?! (Was having a lot of fun until this struck :) )

In the OCI console, go to the instance, and click on the "console connection", this will show you 2 options, one is create local connection, which will allow you to upload a new ssh key file. Or you can create a console connection and then update the authorized_keys file with your new id_rsa.pub contents

Console connection did NOT work for me. That's why I went by attaching the volume to another instance. The documentation I followed suggests to mount /dev/sdb3. However that did not work for me. Instead, I mounted /dev/ocivolume/root, and modified the ssh key there, and now works!
