Cannot install modules on Odoo 9 - module

Question

after uninstalling some modules a strange error appears whenever I try to install modules and i can't install any of them.
Odoo official modules are affected too.
Can't figure out what could the problem be.
Here is the traceback:
Odoo Server Error
