Downgrade to Debian Wheezy Stable 7.x
Description
With this Guide you can downgrade to the stable version of Debian Wheezy, if you enabled a wrong repository with newer packages and getting errors installing something new.
Repositories
1. Disable all custom Repositories
Make sure, you disabled/deleted any custom repositories in "OMV-Extras":

2. Apt-Pin Packages
Now we have to use the Apt-Pinning feature to get the correct default release tag for our apt downgrade
Modify or create the file /etc/apt/preferences and put following text in it:
nano /etc/apt/preferences
copy and paste Shift+Insert the following text
Package: *
Pin: release a=stable
Pin-Priority: 1001
Hit Ctrl+O to save and Ctrl+X to exit
3. Update and upgrade (downgrade) Packages:
run these commands on the CLI:
apt-get update
apt-get upgrade
apt-get dist-upgrade
Apt will ask you for downgrading all packages now.
Just say yes, let it go and pray that all packages getting installed and downgraded properly!
4. optional: Install failing packages again
If some packages failing on downgrade you have to purge them by doing:
apt-get purge yourfailingpackage
and reinstall them with
apt-get install yourfailingpackage
after purging it.
You are on stable Debian Wheezy now!
