After pulling the code and submitting, I found that I could not submit the commit to gitlab, and it prompted that a password was required. After I found that the key and the public key on gitlab were both correct, I tried to print the SSH connection log between the local and gitlab server. The log is as follows:

The key matching log prompts no mutual signature algorithm. To enable display configuration, add the following configuration in the ~/.ssh/config file (create one if it does not exist):
PubkeyAcceptedKeyTypes +ssh-rsa
After modifying the configuration, save it and retest, and the authentication will be successful.
