Thank you so much for your answer
There is not the option “continue.” You have to choose between “accept and install” or “decline”. Clicking “decline” it closes.
I am afraid I am not able to do that. Besides I do not have any more the older wine version. (s.3)
3)I have installed 18.04. only three weeks ago. I have partitions. On the other one there is still 14.04 for a case of emergency. When installing wine 4 on 18.04, I followed exactly the instructions, which said to get completely rid of wine 3. So I did that with the help of synaptic and sure enough it is completely removed.
I intended to follow your suggestion (which I think is great), booted 14.04 and saved the new Garmin there. To my great surprise, it turned out that now also on 14.04 there is the new version of wine. I had always heard that different partitions know nothing of each other (?!).
Anyway, I have learned something: it looks like it depends on the new wine (and not on the new Garmin), because the new wine does not work with the old Garmin versions on the old Ubuntu either (wine 3 did).
So I thought, my best option could be to uninstall again wine 4.0 and try to reinstall wine 3, if it is still available. (Otherwise use the computers of the flight school and show everybody that Linux has problems).
What do you think?
Thank you so much,
