I went back to the laptop and re-archived the game... then played a bit more (IE, past the end-of-move condition) and the re-archived (different archive name). Played a bit more and then re-archived (again with a different name). The archive files were copied over the windows network to the Ubuntu machine and then moved to the ~/.config/... directory. I tried loading each of the archives - each time starting the game from the desktop - and it failed with the "object not found" message each time. I also tried deleting the game from the "Load game" list that comes up before restoring the archive and got the same result. I also did a binary compare between the windows network shared version (which was created via a copy/paste in Explorer from the Win10 laptop) and the copy over in Ubuntu ~/.config and the files are identical so there was no translation or failure in the copy (unless windows screwed up the copy/paste from the laptop local drive to the network location).
In short the following were all tried:
- Re-archive & load from the "turn is finished - wait" condition
- Re-archive & load from the start of the next move.
- Re-archive & load from several turns & moves later.
- Went back to the laptop, removed the game from the 'load list' & restored the archived game to the laptop (replacing what was there) - this worked fine - game loaded without problem.
The first two and fourth were loaded both before & after removing the previous restore from the "load list". All attempts to load were the first thing done after the game was started from the desktop.
I'm guessing I'm not making some brain-dead error in the process because the laptop loads the archive just fine & I'm doing the same thing over on the Ubuntu system. This is only the second time I've tried to move a game -- the first time it worked great -- although that old laptop died and this is a different Dell.
Not sure where to go from here...
