yesterday I did a fresh install of latest OMV 5.6.13, all went well.
During initial set up I updated the system via the gui, which now gives me version 5.6.15-1. I then installed the OMV extras via ssh using the following command, wget -O - https://github.com/OpenMediaVa…ckages/raw/master/install | bash, No issues there.
I then installed the Flashplugin from gui.
Now, when I try to install any further plugins (specifically R Snapshot, though I also tried others) from the plugin menu via the Gui I get errors and installation ultimately aborts and all I can see is various could not resolve and failed to fetch errors.
I am not sure I will be able to repeat the exact issue as during writing this post I thought I will check one more time if there is a setting I may have missed... and I thought I had... I looked in the OMV extras menu on the gui and saw there was an option in the Settings tab of the OMV extras menu with one of the three repo options being Extras Repo this was not checked so I checked it and tried to install the R Snapshot plugin but the plugin was no available in the Plugin menu and neither were any of the others that had previously been there. It now only shows the enabled plugins which are the Flash and Extras packages.
Though at this point I cannot recreat it I did attempt Update from the OMV Extras menu and essentially got this result, which was similar.
I actually had similar issues regarding installing on the previous version of OMV 5 I had installed hence why I did a fresh install with the latest image.
Any help is much valued, I have tried my best to fathom it out myself and search the net for answers.
