Yesterday i was connected to my droplet via SSH as usual, doing my work. Then i has issues with zsh so i removed it to use the default console:
sudo apt-get --purge remove zsh
Then I exited and now I can’t connect anymore.
Via SSH I get the “permission denied” error. Via web console it looks like the login worked (I see the welcome screen for a second), and then it goes back to the login screen again.
Right now i have no way to log in. I tried re-adding the SSH key via dashboard and it says that the SSH key is already installed, so that’s not the problem (but i knew it).
I believe that after removing zsh now i don’t have a default shell.
What could I do??

Hello there,
You can check our article on How to Upload an SSH Public Key to an Existing Droplet
You can access the droplet from the DigitalOcean console and then temporary enable the PasswordAuthentication on your droplet and access the droplet with a password to upload the ssh-key.
If you haven’t created new pair of keys you’ll need to do that first.
You can enable PasswordAuthentication for your Droplet by modifying your
/etc/ssh/sshd_config
file. Once set to Yes restart the SSH service and connect via an SSH client for a more stable connection. You can then modify your~/.ssh/authorized_keys
file to add the appropriate public key.This change can be made from the DigitalOcean’s console. If you’re having issues accessing the console you can then reach to our amazing support team that can help you further with this.
To enable the
PasswordAuthentication
follow these steps:sudo nano /etc/ssh/sshd_config
PasswordAuthentication
from “no” to “yes” and save the filesudo nano ~/.ssh/authorized_keys
sudo nano /etc/ssh/sshd_config
PasswordAuthentication
from “yes” to “no” and save the fileYou can then upload the key using this command:
ssh-copy-id -i ~/.ssh/mykey user@droplet
Hope that this helps! Regards, Alex
For those who face the same problem. It turns out, when I reset my through chsh, I accidentally set root sh to be bash instead of /bin/bash.
To fix this:
@snapshooter Now I created a new droplet (NOT from snapshot), and I can connect regularly with the same keys.
So there is not an issue with SSH keys. I don’t know how to troubleshoot that droplet now. I believe it’s because it does not have a default bash anymore.
