Hello, this is Brian Lee and I am new to this forum.

 

I tried downloading the latest forge 1.12.2 jar, in which it is successful. I downloaded the installer because my computer is Linux. 

 

Now here's the problem. I double clicked the jar file I downloaded and it did not run. Then I went to terminal in Linux and run the jar file and this is what I get:

Is something wrong here? Thank you!

I know that I can't post within an hour, but since it is 19 hours later I can post it here, right?

 

Anyways, I am concerned that I can't run the installer jar file, so please help me. I have java installed but the installer jar forge file does not work, so that's the problem I have.

You can post within an hour, it just has to be more substantial(meaning actually provide information) than just "bump".

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

You may have a network issue, try running it with the --offline flag

--offline is an argument for the installer

I tried running:

 

java --offline

 

And I got an error:

 

Unrecognized option: --offline
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

 

Do you mean --offline? I tried running --offline without the word "java" and it says "--offline: command not found"

I downloaded the libraries, but the forge wouldn't start. I did not use the cracked launcher and I used the authentic launcher (the one I bought).

I would assume the computer you are running this on has internet access, is this correct?

This computer isn't on a weird network (i.e. a college internet connection that filters traffic), right?

And besides, I downloaded the corresponding libraries from the issue above and the mod installer works, but when I tried to run forge on the authentic launcher (not the cracked one) it wouldn't start.

While I did download the corresponding libraries to properly install forge offline, I couldn't start forge even though it is on the forge profile. I still use the authentic launcher and NOT the cracked launcher because in this forums cracked launchers are illegal and thus being banned if someone uses it and mentions it on the forums.

If you were able to get it installed into the launcher please provide a debug.log

The EAQ thread and my signature might offer clues.

Since I am new here, I have no idea what the EAQ thread means, so all right then.

It's the thread stickied at the top of this forum called "Rules and EAQ - READ FIRST OR YOU WILL GET BANNED!!!".

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

Anyways, I am downloading the 1.13.2 forge. But when I start the authentic launcher, there is no 1.13.2-forge-25.0.48 for the version, even though I have installed it. I don't know if I can make another topic or continue using this.
