I just installed odoo15, but when I tried to start it, I get "Internal Error Message", and I get the follwing message from log file:
return self.app(environ, start_response)
File "/opt/odoo/odoo/http.py", line 1464, in dispatch
explicit_session = self.setup_session(httprequest)
File "/opt/odoo/odoo/http.py", line 1345, in setup_session

File "/opt/odoo/odoo/http.py", line 1291, in session_store
path = odoo.tools.config.session_dir
File "/opt/odoo/odoo/tools/config.py", line 714, in session_dir
assert os.access(d, os.W_OK), \
AssertionError: /var/lib/odoo/sessions: directory is not writable - - -
How to fix this issues please
Thanks
Make sure you start odoo with the user that is able to write in this directory.
My guess is that /var/lib/odoo/sessions is only writable by root. Did you create a new user for odoo?
Try this (with odoo:odoo being the user and the group of your odoo system user):
sudo chown -R odoo:odoo /var/lib/odoo
Otherwise make also sure it IS writable:
sudo chmod +w /var/lib/odoo/sessions
