When trying to install the (Dutch) version 7.2.0, I got the following message;
The downloaded copy of Libre Office is not valid and can't be installed. Due to either an incomplete download or a network problem. (The latter is certainly not the problem).
Try to start the update once again when everything is completed.
(I tried 3 times without success)
The hashes were inverted in the updater. Sorry about that.
Sometimes, the impossible can become possible, if you're awesome!
Thank you for the swift reply and for the fix!
