Hello,
I'm running omv 2.2.14 on my NAS system. I was trying to follow this guide to take a backup of my configuration.
Unfortunately, accidentally (by my negligence 
) I uploaded the openmediavault-omvextrasorg_latest_all3.deb package in the UI plugin section wich is for the omv3.x.
When I tried to install it I got the following message:
Building dependency tree...
Reading state information...
Some packages could not be installed. This may mean that you haverequested an impossible situation or if you are using the unstabledistribution that some required packages have not yet been createdor been moved out of Incoming.The following information may help to resolve the situation:
The following packages have unmet dependencies:openmediavault-omvextrasorg : Depends: openmediavault (>= 3.0.67) but it is not going to be installedE: Unable to correct problems, you have held broken packages.<<< *************************************After that I am unable to remove this package from the plugin page.
I followed the guide from omv-extras.org and installed it from the CLI.
After that the openmediavault-omvextrasorg 3.4.25 seems to be installed (blue tick mark on the left) but I don't see any extra plugin in the Plugins section (after pressing the Check button) or a new OMV-Extras tab under the System tree.
Is there any way to fix the problem? (or is not a problem at all and the extras are somewhere I cannot see them?)
Thanks in advance.
