curl: (35) gnutls_handshake() failed: 公钥签名验证失败

Question

我有一个问题，当我执行 curl 请求或 git push 时，显示给我

curl: (35) gnutls_handshake() failed: Public key signature verification has failed.

curl --version

curl 7.50.1 (x86_64-pc-linux-gnu) libcurl/7.50.1 GnuTLS/3.5.3 zlib/1.2.8 libidn/1.33 libssh2/1.7.0 nghttp2/1.14.0 librtmp/2.3 Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtmp rtsp scp sftp smb smbs smtp smtps telnet tftp Features: AsynchDNS IDN IPv6 Largefile GSS-API Kerberos SPNEGO NTLM NTLM_WB SSL libz TLS-SRP HTTP2 UnixSockets

我已经完成了:将 curl 更新和降级到 7.38 版，但这对我没有帮助。
对不起，我的英语，tnx。
