Package: pyhoca-gui Version: 0.5.0.3-20150124 tags +win32 When attempting to connect to a server using Pageant ("Discover SSH keys or use SSH agent for X2Go authentication"), you get this error: An unknown error occurred during authentication This is a regression between 0.5.0.0-pre02 (the previous build) and 0.5.0.3-20150124 (the current build.) I've attached the debug logs. (On Windows, logs are under %AppData%\pyhoca-gui\ ) 0.5.0.0-pre02 bundles paramiko 1.14.0. 0.5.0.3-20150124 bundles paramiko 1.15.2 This appears to be a regression in paramiko, #461: https://github.com/paramiko/paramiko/issues/461 @ThiefMaster's commit fixes the issue fine. The paramiko maintainer seems to be away, so it has not been merged yet. I will release a new build of PyHoca-GUI with the paramiko commit applied.
