Python plugin issues

[Nothing4You]

Hi,

I'm currently on latest git (e41b644).

I click on "More services…", a window pops up loading the latest plugin infos from GitHub.
I choose these settings

and after confirming I get this

Both my python2 and python3 can import Crypto without any problems if I call them manually in a terminal.

Hi,

You can try checking what paths the ScreenCloud python interpreter is using and compare them to your regular python installs. Go to Preferences and hit Ctrl+D to open the debug console. Type:

import sys
print sys.path

Also, keep in mind that the git version is not ready for release. It still has a few issues and I'm currently struggling to make it work properly on Windows and OS X.

Crypto is actually located in /usr/lib/python2.7/site-packages/Crypto.

I'm aware of the fact that the git version is not stable, however, if I can report bugs that get fixed before the next release it's usually better than releasing and after the release getting all the bug reports.

[olav-st]

Try the newest git version (4e1b8b9). It should have site-packages included now.

Also, It's great that you want to help find bugs. Just don't excpect anything to work well ;)

Thanks, plugin loads without errors now.
I tried to upload something via SFTP and forgot to change the port (it was on 21, either wrong default or problem during upgrade), now I'm getting this:

Traceback (most recent call last):
  File "<string>", line 102, in upload
  File "/home/rschwab/.local/share/data/screencloud/ScreenCloud/plugins/sftp/modules/paramiko/transport.py", line 1007, in connect
    self.start_client()
  File "/home/rschwab/.local/share/data/screencloud/ScreenCloud/plugins/sftp/modules/paramiko/transport.py", line 466, in start_client
    raise e
paramiko.SSHException: Error reading SSH protocol banner

Port 21 runs an FTP server, so there should probably be a nice error message explaining what's failing.
Otherwise, keyfile auth works without any problems, which is an awesome new feature.
Thanks!

[olav-st]

Thanks for the heads up. The default port was set to 21 for some reason. I've fixed it with olav-st/screencloud-plugins@2f74e98

[Nothing4You]

I'll close this issue and create a new one for better error handling.
