"No Such File or Directory" on Cisco IOS XE router using net_put

[JustinGrote]

SUMMARY

Transferring a file to a cisco router results in Initializing SCP session of remote file [bootflash:cat9k_iosxe.17.12.04.SPA.bin] for write failed with error [b'Socket error: No such file or directory'

I looked through the source code, the failure occurs when pylibssh calls the libssh.ssh_scp_init method. But, I didn't go any further. (See line 64 here: https://github.com/ansible/pylibssh/blob/devel/src/pylibsshext/scp.pyx)

Context: https://stackoverflow.com/questions/76789209/no-such-file-or-directory-error-when-using-ansibles-net-put-and-libssh-to-a

Workaround

This works fine if ansible_network_cli_ssh_type: paramiko

Possible related issue:

• Unable to transfer files using SCP to a Cisco IOS device #325

That one was closed out with the following Pull Request:

• Do not crash if remote file does not exist #620
• Based on the PR comments, this is available in pylibssh version 1.2.1

Sadly this bug report (Issue 673) says the trouble was seen with pylibssh version 1.2.2 (newer than the above PR release version)

@Jakuje mind taking a look?

Can you get verbose libssh logs from the connection. Not sure if providing -vvvvv to the playbook will show enough information or we will need to wait for the #597 to get all the libssh debug logs.
