Any ideas how to install FTB mod for minecraft?

xaldron

Hello. New user to both solus and Linux here. I've managed to install minecraft allready thanks to the Solus guide. However, I'm somewhat lost as to install this mod: https://www.feed-the-beast.com/

I tried "wget https://apps.modpacks.ch/FTBApp/release/202007161516-479dedc615-release/FTBA_unix_202007161516-479dedc615-release.sh" to download it (link is the same as when you click download for linux on FTB website). But I am only getting a text file on my system. Does anyone have any pointers for me where to go from here? Any help would be greatly appreciated. 🙂

Ok, make chmod +x FTBA_unix_202007161516-479dedc615-release.sh and double-click the file or run in terminal

That file is a shell script. You have to set the permissions to "executable" and then run it, like so:
chmod +x chmod +x FTBA_unix_202007161516-479dedc615-release.sh
then
./FTBA_unix_202007161516-479dedc615-release.sh
This will open the FTBA installer.
I just ran it, installed the "Sky" variant and launched it. Seems to work fine.

edit: ninja'd by @pomon 😀
edit2: nevermind, actually launching Minecraft failed. Something went wrong along the way.
Pretty sure it has to do with it trying to use its own Java, as far as I can see. Not sure how to fix it though.

Thanks a lot for the super quick aid guys! It appears I chose the right distro and community. 😄 I don't have time to try out the solutions yet. But when I do I will let you know how it went.

Staudey Perhaps I would have to edit the exec path to launch FTB with Java, as I had to with the Minecraft launcher?

i installed with tutorial later movie

pomon I did get to the part where I can open the FTB app and download the mods. However, when I click play I get the following Java error:

Unable to locate the Java runtime.
Error details: Suksess
Filename on disk: java
Path: /usr/bin/java
Exists: Nonexistent

I don't get this error when I use the normal Minecraft launcher, after having used the tutorial which you are refering to.

Edit: I might have figured it out. In the launcher where I select "edit" on the selected mod, I could then again click more options and locate OPENjdk-8 in the "java executable" options from there. Seems to work now, but will have to see once the mod is finished updating. At least it launched the updater.

pomon

show eopkg li | grep openjdk and ls -l ~/FTBA

I'm running MultiMC, which can install Feed The Beast (and other) modpacks from CurseForge.

I've had the most success with openjdk-8. It looks like pointing the MultiMC Settings at the /usr/lib64/openjdk-8/jre/bin/java binary will make all profiles inherit it?

I'm currently making do with a close-to-vanilla Fabric modpack called Fabulously Optimised where I've added a few extra convenience mods on top (map, more info, more convenient tree chopping etc.) and the PureBDCraft 128x resource pack(s).

ermo Very interesting. I will be sure to look into MultiMc as an option, soon as I have the system to run the mod tough. 🤣

An update on the progress.
I was able to start the loader (not the updater as I previously called it) when changing the settings of the FTB mod in the launcher: - edit - more options - java executable and locating the openjdk-8 executable.
However, it appears that the system I was using for this is too old and outdated to handle the FTB mod, as the loader is having a real hard time lanching the game (been loading for over an hour now, with the memory used/total bar at maximum/red capacity).

TL;DR my problem is no longer OS related but hardware related

So in conclusion I suppose this thread can be frozen until I've upgraded my system with better hardware. I still want to thanks you a lot for all of your help @pomon @Staudey and @ermo! I am confident I chose the right Linux distro. 😀

xaldron You could just choose a lighter modpack? There are many different FTB modpacks on CurseForge.

FTB modpacks can use up a lot of memory too -- 4-8GB for the java runtime engine alone. So if your PC only has 4GB of RAM, you'll need to load a lighter modpack and configure java to only use up to 2GB of memory for instance.

ermo Sorry for the late reply. Iv'e been travelling a lot lately. The computer upon I was installing minecraft and FTB was on my old system which I gave away to my nephew, and it was for him I installed those games. He was however, happy and content with the original Minecraft for now and we will look into FTB more next time I visit them and I bring him some new and improved RAM. But, your tip is very handy and I will look into it/ask more about it next time I am going there to try and get it up and working again. 🙂
