I am not able top update website _sale module via command line
becasue I am getting error this odoo is installed by automated script so there is no odoo scripts available
Of course you can update it, just locate your Odoo home and use the proper command. Depending on your installation script, Odoo home may be at different places. Additionally I recommend you to 1. learn backup, 2. learn read the documentation, 3. use recommended procedures if you are not skilled enough to do otherwise, 4. learn to read your logs.
