Conversion didn't finish normally, the resulting world may not be playable.

[CHJ85]

I keep seeing this message.
Tried to convert 10 saves. Some are very basic. So this is odd.
They all show this message and none of them are playable.
Am I doing something wrong? Are any other software required?
Very little documentation here.

What's the full console output? What os did you use? What mc version is this map from?

[CHJ85]

Ubuntu. And sorry, I forgot to provide the output:

[CHJ85]

Any idea why this could be?

[sofar]

Bug in code. Unfortunately really deep in the nbt parser that I don't know of a fix.

What MC version was used to make this map?

[CHJ85]

Not sure. Didn't make it myself. I only download maps.
Could the problem here be that the minetest mods are not in my local home directory?
I installed them with Synaptic, so they're in /usr/share/games/minetest.

[Ekdohibs]

I just pushed a change that might at least partially solve the issue, could you try it to see what you get? The problem is unrelated to mods not being in the local home directory, it is instead related to Minecraft having probably updated the save format.

[CHJ85]

Thanks, but no luck.
I tried downloading the original map from the planetminecraft site. This worked somewhat.
The conversion was a success according to the script.
But an init.lua file was missing:

[Ekdohibs]

Hmmm that's another problem. Did you try to run get-mods.sh script?

[CHJ85]

I mean, it asks if I want to download the mods after the conversion, which I do.

[Ekdohibs]

That's interesting. I'm not sure why it does that, maybe @sofar has a better idea.

[sofar]

re-run the get-mods.sh script and paste the output, please.

[CHJ85]

Okay, so I tried again. Same error.

[sofar]

I obviously need the output from the get-mods.sh script. Not the output from the game after you ran it.

[CHJ85]

Yea, sorry. I see what the problem is.
Can't run the script because;
./get-mods.sh: 5: ./get-mods.sh: Syntax error: "(" unexpected
./get-mods.sh: 24: ./get-mods.sh: Bad substitution

[sofar]

what is the output of /bin/sh --version on your system?
