Python language server - offline mode

[bryanSME]

Should the Python language server work in offline mode? My question may be related to #3809

I'm trying to upgrade from 5.11 to 5.15 mainly for the python language server. I'm running this in offline mode. When I create a new workspace, Python Defauly Python Stack with Python 3.5.1, pip 8.1.1 the work space starts with errors "missing /home/user/.cache/pip".

Ignoring the error, I create a new project and double click on the "main.py" file what was created for me. This throws the error,

Can't start language server process. Got error: /home/user/che/ls-python/launch.sh: 1: /home/user/che/ls-python/launch.sh: pyls: not found

the launch.sh file does exsist and as expected, it contains "pyls". running pyls from the command line yields "bash: pyls: command not found". At thins point, I'm assuming that Che needs to download some files to get the language server running but that's as far as I've gotten.

@bryanSME yes, the agent script downloads binaries and if you are offline, an agent won't start:

Closing the issue. In future, ls binaries delivery methods may change.
