Thanks for your feedback, but this is not related to the update problem at ovistore, I think. Did you install a testing version between 0.6.0 and 0.7.3? In 0.7.3 the same data structure is used as in 0.6.0, but in other version it might have changed, so that could be the problem. Please post the error message in the future so I have a chance to find the reason for this error. .
