Hi All,
this is the first time I am communicating with the lava community.
I am facing a problem with the lava installation.
I need step by step installation procedure and after installation one example demo for the understanding purpose.
(send all steps because I am first time using the lava )
in that, I am facing a problem when I type the command 
$sudo apt-get install lava-server       
then getting the following error message :
---------------------------------------------------------------------------------------------------------------------------------------------------------
 File "/usr/lib/python3/dist-packages/lava_rest_app/v02/routers.py", line 22
   from import views
             ^
SyntaxError: invalid syntax
migration
dpkg: error processing package lava-server (--configure):
installed lava-server package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
lava-server
E: Sub-process /usr/bin/dpkg returned an error code (1)
-------------------------------------------------------------------------------------------------------------------------------------------------------------
please send the information from the first command of installation to the last command of installation which I need to use.
Note: I am using Ubuntu 18.04.5 LTS. 



Thank You.
