Setting up ssh-agent to access Krita repository on KDE Neon

1. Make sure you remove all explicit calls to ssh-agent in your .bashrc and .bash_profile files.

2. Disable ssh support in the GPG Agent service:

   1. Comment out line enable-ssh-support in ~/.gnupg/gpg-agent.conf

   2. Disable the ssh-related socket as well:

      systemctl --user stop gpg-agent-ssh.socket
      systemctl --user disable gpg-agent-ssh.socket
      systemctl --user mask gpg-agent-ssh.socket
      

3. Create ssh-agent service.

   systemctl --user edit --full ssh-agent.service
   

   This command will show you an OS-specific template of the service file. You can modify it or just use the following example:

   [Unit]
   Description=OpenSSH Agent
   Documentation=man:ssh-agent(1)
   Before=graphical-session-pre.target
   Wants=dbus.socket
   After=dbus.socket
   
   [Service]
   ExecStart=/usr/lib/openssh/agent-launch start -- -t 60m
   ExecStopPost=/usr/lib/openssh/agent-launch stop
   

   If you want to modify the timeout for your SSH keys, change the -t 60m flag.

4. Reload the systemd daemon

   systemctl --user daemon-reload
   

5. Start the service

   systemctl --user start ssh-agent.service
   

6. Check if everything loaded correctly:

   systemctl --user status ssh-agent.service
   

7. OpenSSH’s agent-launch uses DBus service to push variables into the user’s environment. You may need to reboot the entire system to make sure the environment variable is properly loaded. Check the content of $SSH_AUTH_SOCK in your shell and compare it with the values in the status report of the service to verify your changes.
