I had the same problem it seems it is a problem of flask and its dependencies.
I installed a previous version of werkzeug and it seems to work

pip install werkzeug==0.16.1

Hope it helps

Hello, check your flask version is 0.12.2 and then install werkzeug 0.16.1
Hope it helps

[hatem2018]

Hello, thanks for your reply but unfortunately this did not solve the problem, i have this two version for flask (0.12.2) and i reinstalled werkzeug with 0.16.1 version (even old one i tried to install it but the same issue), i also tried cuckoo venv installation and global installation (both same result) :(
I am using OS ubuntu 18.04 and Cuckoo 2.0.7
it's possible to downgrade cuckoo to 2.0.6 without problem to avoid this incompatibility ?
your advice is most welcome. thanks a lot

[hatem2018]

Thanks it solved my issue, when i installed werkzeug with 0.16.1 version in cuckoo user profil
