I guess that means it didn’t work then?

Maybe time to order a Raspberry Pi?


I have 3 rpi computers but I had hoped to use a better computer.

I have been able to get it to work on Windows 10 and on other versions of Linux. I am not quite ready to give up but am having little to give me hope.

Maybe try a re-install then?

Have you checked that all the paths referred to in your server.properties do actually exist, and that they have the appropriate read/write permissions?


The file paths?

I have not checked each path. I had expected it to install correctly. I will look.

Do you have a quick list of paths?

Where should I find the /admin folder?

Should it be in the root of the computer or the root of the server folder?

I meant the paths in your server.properties like these…


I don’t see a file or folder named admin.

I deleted the user file and let it recreate it and it now lets me login. Thanks for the help.
