Deprecated - Switching from default mongodb to mongodb-10gen

The method here is deprecated and no longer supported

Older FileCloud debian packages had dependency on the default MongoDB packages bundled with Debian and Ubuntu distros (mongodb-server and mongodb-clients). The required mongodb version for FileCloud is not available in these default packages. So it will be necessary to switch to packages from mongodb-10gen repository. Follow these steps switch from default mongodb packages to 10gen version without uninstalling any other packages.

Add the mongodb-10gen package repository. Edit the file /etc/apt/sources.list and add the code below to the sources.list file and save it.
```
deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen
```

Add GPG Key

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10

Update debian package cache
```
sudo apt-get update
```
Remove dependency of mongodb-server from FileCloud package. Edit the file /var/lib/dpkg/status, search for package filecloudprereq.
Change the dependency setting by changing the line
```
Depends: apache2, php5, php5-gd, php-pear, php5-dev, build-essential, mongodb-server
```
to
```
Depends: apache2, php5, php5-gd, php-pear, php5-dev, build-essential
```
Now the dependency of FileCloud debian package on default mongodb packages is removed, uninstall the package.
```
# sudo apt-get remove mongodb-server mongodb-clients
```
Install the new mongodb-10gen package.
```
# sudo apt-get install mongodb-10gen
```
(Optional) Change the dependency of FileCloud package, so that future upgrades will be easier. To do this edit the file /var/lib/dpkg/status, search for package filecloudprereq.
Change the dependency setting by changing the line
```
Depends: apache2, php5, php5-gd, php-pear, php5-dev, build-essential
```
to
```
Depends: apache2, php5, php5-gd, php-pear, php5-dev, build-essential, mongodb-10gen
```
