How well does it work with paid packages with you? I did the back up and I'm currently going through the deb files and i don't see my overboard in there. Im guessing since the dev put good crack protection on it this app can't back it up?
OpenBackup uses standard apt calls (specifically, apt-get). Everything apt is able to fetch is fetchable by OpenBackup.
In my case, it has always been able to fetch all the paid-for packages. I've purchased many; however, unfortunately, Overboard isn't one of them so I couldn't test this myself. However, given that I have never had any problems with fetching the commercial DEB files from the same dev with OpenBackup (I've even provided proof of this in the second screenshot in the post I linked to above), I do think you have a local problem.
What happens if you run "
backupdebs" (the script OpenBackup uses for fetching DEB files) in the command line? Can you post the full console output of the script (as I've did above)? Based on that, I could be able to pinpoint the cause for the problem.
