[CLOSED] Thunar SFTP - How to mount remote share

[vancouver]

Update!
for some reason, downloading the SSH key from one of the web servers didn't work. Generating an SSH key locally and then uploading it (cPanel) worked perfectly. If anyone has a need to edit web pages live on the server then also start the SSH daemon under: Settings > Session and Startup > Application Autostart and finally, check the last box at the bottom "SSH key agent (GNOME key ring)".
After that, it's just the usual. Add the private key via ssh-add and Thunar will do the magic dance.

Here is the original post (for reference).

Hello,

I just installed openssh and did sudo systemctl start sshd.socket (read that in an arch wiki page)
Then I tried to add the ssh key which I downloaded from my web server with
sudo ssh-add /home/username/.ssh/keyname_key

and got this error msg: Could not open a connection to your authentication agent.

Does anyone know of a tutorial that works on ArcoLinux and goes trough the steps?
I'd love to mount a web server locally so that I can edit the pages. Thanks - v
