My VPS server version - ubuntu 18.04 

python version- 3.8.13

Already install every dependency. I tried several time to install odoo15 but every time I face same issue. In the same environment I try to install odoo14. It works perfect. In same environment why odoo15 won't work? Does anyone face same problem? 

See ----

root@skt:/opt/odoov15/odoo# ./odoo-bin

Traceback (most recent call last):
