Only java version 8 is supported, you need to install and use that - both versions can co-exist, but if you don't know how to do that - uninstall the current version and only have java 8 installed.

oh, okay i did this. Thank you!

But now ofc i have another problem.

After server started now i have Incompatible FML modded server. I downloaded from this link (link from launcher):
https://api.modpacks.ch/public/modpack/6/71/server/linux . I have version 1.5.0. It turns out that there is a difference in the versions of individual modifications and this makes it difficult to set up a server and play freely. I tried with windows version, but there is a problem too.

when you ran the script, what packid and version did you put on the command line?

I tried it out and installed a fresh server on ubuntu and a fresh install of the client on windows, had no issues connecting to the server.

So make sure you got the right versions, and install the pack if needed, both server- and client side.

i made only ./serverinstall_6_71

and after this screen i press Y then enter. I see the same version modpack with that 1595349988203.png
