Can someone help on this? Thanks in Advance.

Answer 1

Just installing memcached is not enough. You will also need to install python memcache module which is provided separately by python-memcache and python-pymemcache . I am not sure which one is used here.

You can try installing them with apt-get and see which one works for you.

Now working.. I have installed murano api and murano dashboard in different venv. I have missed to install memcache in munano api venv. When i'm tried after install memcache in murano api venv..Now working fine..

@tutuDajuju Thanks for the Help...
