Environment variable not set :SECRET_KEY

[cahaya42]

After a fresh install, I ran librephotos-cli clear_cache

Traceback (most recent call last):
  File "/usr/lib/librephotos/backend/manage.py", line 11, in <module>

NameError: Environment variable not set :SECRET_KEY

Solution
Add the following line to /etc/librephotos/librephotos-backend.env

SECRET_KEY=$BASE_LOGS/secret.key

Ideally, this should be added to resources/etc/librephotos/librephotos-backend.env

It should read out the secret key anyway, because of this entrypoint file. We either create a new one and read it, or we read an old one. I am not sure, why it's not working on your system.
