omv-update has been failing due to not getting sources properly from bintray repos from what I can tell. I have tried several things to try to fix, such as omv-aptclean, uninstalling and reinstalling omv-extras using webgui and via command line with no success to fixing the issues. Not sure where to look next or maybe others are having same issues with this repos?
Code
Reading package lists... Done

any suggestions/help would be appreciated.
