Original GitHub issue: https://github.com/retspen/webvirtmgr/issues/244

I followed the installation guide (from https://github.com/retspen/webvirtmgr/wiki/Install-WebVirtMgr) on a fully new Ubuntu 12.04 but when I ran the following command (in the fourth section) :

sudo cp /var/www/webvirtmgr/conf/initd/webvirtmgr-novnc-ubuntu /etc/init.d/webvirtmgr-novnc

An error occured: the webvirtmgr-novnc-ubuntu folder didn't exist.
In fact when I list the content of the /var/www/webvirtmgr/ folder this is what I see :

thibaudsowa@nuc:/var/www/webvirtmgr$ ll

drwxrwxr-x  2 www-data www-data 4096 févr. 18 22:28 ./

-rw-rw-r--  1 www-data www-data 1431 févr. 18 22:27 wsgi.py

Does the error come from the third section (Setup Nginx)?

$ cd ..
$ sudo mv webvirtmgr /var/www/

I'm not at all an Nginx expert...
Thanks for help!

I run into the same error, delete everything in /var/www, download the files again and use the following command to move the files correctly:
sudo mv webvirtmgr /var/www/webvirtmgr

So now I can follow next steps, but when I want to connect on the web interface I have an 500 Internal Server Error...

This is what output in my console:

Hmmm... ok so with that:

sudo chmod 777 /var/www/webvirtmgr/webvirtmgr.sqlite3
sudo chmod 777 /var/www/webvirtmgr

....it works!
It is just a right problem.

So I think that the www-data user is not used to launch the website.
How can I fix this without the chmod 777 trick?

My database has 644, are you sure that the nginx user is the owner of the whole /var/www/webvirtmgr folder?
Use the following command again:

chown -R www-data:www-data /var/www/webvirtmgr

and change the permissions to 644.
