Hi,
When I try to install odoo v13 CE, I got the same issue. And I got it resolved by downgrading the version of "passlib" from v1.7.1 to v1.6.5. In the Odoo 13 requirements, v1.6.5 is mentioned.
*sudo pip3 install passlib==1.6.5 *

pip3 install passlib==1.7.4

Use
*pip3 install -r requirements.txt. *It works for me. I used *sudo pip3 install -r requirements.txt, but it won't work.*
