Hi, When I try to sftp upload through curl executable I am getting following errors. Keys are configured properly and curl sftp fails with Failure establishing ssh session: -44, Unable to ask for ssh-userauth service error.
Below is the curl version which has been installed. curl 7.82.0 (aarch64-poky-linux-gnu) libcurl/7.82.0 GnuTLS/3.7.1 (OpenSSL/3.0.7) zlib/1.2.11 libidn2/2.3.0 libssh2/1.9.0 Release-Date: 2022-03-05 Protocols: dict file ftp ftps gopher gophers http https imap imaps pop3 pop3s rtsp scp sftp smb smbs smtp smtps telnet tftp Features: alt-svc AsynchDNS Debug HSTS HTTPS-proxy IDN IPv6 Largefile libz MultiSSL NTLM SSL TLS-SRP UnixSockets root@5GSM-SRC234610033:/etc/ssh# curl -vv -u ftpuser: --key /etc/sftpkeys/id_dsa --pubkey /etc/sftpkeys/id_dsa.pub -T //var/tmp/file.txt sftp://ftpuser@[2a00:8a03:190::6:6]//home/ftpuser/file.txt -k * STATE: INIT => CONNECT handle 0xaaaabdfd9920; line 1834 (connection #-5000) * Added connection 0.
