  • 无法将代码推送到gitee仓库故障处理(no mutual signature algorithm)

    git@gitee.com: Permission denied (publickey).

    可以看到 no mutual signature algorithm(没有公共的签名算法),高版本OpenSSH没有启用ssh-rsa,

    解决方案:
    1、参考链接,添加 PubkeyAcceptedKeyTypes +ssh-rsa 配置即可
    2、更换秘钥生成算法,使用 ed25519 算法生成
    ssh-keygen -t ed25519 -C "your email"
    3、降低 OpenSSH版本
