VSCode Source Control Extension

Updated Nov 22, 2023 ·

Cannot Push Changes through Source Control Extension​

I was previously using the Source Control extension to push changes to remote repositories, but it suddenly stopped working. Now, when I try to sync my local changes with the remote repository, I get an error.

However, when I open the terminal in VSCode and navigate to the local repository, git status shows everything is up to date on the main branch:

$ git status 

On branch main
Your branch is up to date with 'origin/main'.

nothing to commit, working tree clean

The issue may be related to the known_hosts file. I have two such files: one in WSL and another on the C drive, which VSCode appears to be using. To verify, I checked both file locations, and each has its own set of files.

username@johnsmith:~$ ls -la ~/.ssh/
total 32
drwx------  2 username username 4096 Nov  1 21:13 .
drwxr-x--- 19 username username 4096 Nov  3 08:58 ..

-rwxrwxrwx 1 username username 1132 Nov  3 08:50 known_hosts

Since the keys were old, I decided to generate a new keypair with a passphrase. I logged into GitHub, deleted the old SSH key, and uploaded the new public key.

ssh-keygen -t ed25519

To upload the key, go to GitHub > Settings > SSH and GPG Keys.

Next, I rescanned the key and saved it to the known_hosts file on the C drive.

ssh-keyscan -t ecdsa github.com >> /mnt/c/Users/john.smith/.ssh/known_hosts
info

If you are using RSA keys, use ssh-keyscan -t rsa

I then confirmed the connection from the terminal:

$ ssh -T git@github.com

Enter passphrase for key '/home/username/.ssh/id_ed25519':
Hi username! You've successfully authenticated, but GitHub does not provide shell access.

Finally, I tried to sync changes from the VSCode Source Control extension, and this time it worked.

Update .bashrc

I also updated the .bashrc to use the new key.

$ vi ~/.bashrc 

# SSH Key
eval `ssh-agent`
ssh-add ~/.ssh/id_ed25519
