Like the title says for some reason minecraft can't configure it's home directory.
This is the error i get (in the log):
An error occurred trying to configure the minecraft home at /home/solublecactus/.technic/modpacks/quantum-realm-yt-series for Forge Mod Loader
I'm sorry but I can't include the whole log because it's just to big and I don't know wich parts are important it's like 10000 lines long.
I hope I included enough info, if you need the log let me know.
Anyways, I hope you can help.
