Question

I set up the local file storage according to these steps

http://docs.ckan.org/en/latest/filestore.html

Create location
```
sudo mkdir -p /var/lib/ckan/default 
```
I confirm the location exists and is in the right location
I uncomment the lines
```
ofs.impl = pairtree
ofs.storage_dir = /var/lib/ckan/default
```
I confirmed I have pairtree and argparse installed

I am using jetty as the web server not Apache so I do

sudo chown jetty /var/lib/ckan/default
sudo chmod u+rwx /var/lib/ckan/default
sudo service jetty restart

Then I run this command to start my site

paster serve /etc/ckan/default/development.ini

I then get this stack trace back, I am doing all of these commands inside my virtual environment

Solution

Permission denied: '/var/lib/ckan/default/storage'

It looks like you don't have permission to read and write to this directory. Try running these commands in a terminal:

sudo chown -R `whoami` /var/lib/ckan/default
sudo chmod -R u+rwx /var/lib/ckan/default

OTHER TIPS

For those stumbling on this years later...

I ran into this when trying to setup datastore and run the paster --plugin=ckan datastore set-permissions -c /etc/ckan/default/production.ini command.

I had already setup FileStore as per the docs. What I ended up having to do was upload a resource in the web UI then re-run the command above and the error no longer appeared and the output worked as expected. After uploading a resource the /var/lib/ckan/default/resources and /var/lib/ckan/default/storage directories were created with the proper permissions and the paster command didn't need to try and create them (or so I'm assuming).

Here's some additional resources in case you have a slightly different issue that's causing this error:

Sample 500 error in ckan 2.9

File "/usr/lib/python3.8/os.py", line 223, in makedirs
    mkdir(name, mode)
PermissionError: [Errno 13] Permission denied: '/var/lib/ckan/default/webassets/.webassets-cache'

To remove the permission error;

Set the permission and ownership. The docs on filestore misses out on the ownership and recursive mode

sudo chown www-data:www-data -R /var/lib/ckan/default
sudo chmod u+rwx -R /var/lib/ckan/default

Finally restart your server:

sudo supervisorctl restart ckan-uwsgi:*
