Subject: ValueError: CTR mode needs counter parameter, not IV

Date: Fri, 17 Feb 2017 11:47:13 +0100

Package: pyhoca-cli
Version: 0.5.0.4

Hi,

pyhoca-cli stopped working for me. I expected it to ask me for password,
but instead it raises an exception.

I don't know what happened, because this worked all the time. And I
think I didn't change anything.

The error message is: "ValueError: CTR mode needs counter parameter, not IV"


Used command:

pyhoca-cli --server xxxxxxx -u xxxxxx -R
xxxx-xx-xxxxxxxxxx_xxxxxxxx-session_xxxx

exact apt versions of my client:
pyhoca-cli 0.5.0.4-0~231~ubuntu16.04.1
python-paramiko 1.16.0-1

This issue might have been related to some non-supported Paramiko  
version. Too long ago to hunt it down. Similar issues haven't been  
observed recently.

Closing this issue report in the process of migrating X2Go BTS to X2Go  
GitLab's issue tracker.
