[Solved] Problems with Fedora 25 FTB launcher (Java crashes & SSL errors)

Ansem_of_Nexus · January 26, 2017, 9:26pm

So as the title says I am using feed the Beast Linux legacy launch on Fedora 25 and having serious problems. As of yesterday after updating and restarting, FTB if it doesn't crash on startup, it refuses to do anything because of an authlib fails to download. So let me break up what has been happening and what I have done so far.

first up, after updating I had to do nvidia-xconfig, to get my computer to load gnome. Once that was done, no problems with anything except when I start FTB and it crashed right away.

Copy of the latest crash

A fatal error has been detected by the Java Runtime Environment:

So wondering what happen, I started it up again from terminal. This time it started, but ran into a different problem, and spit out a SSL handshake failed, so it wasn't able to download something for FTB's Authlib.

So I looked that up, it seems that for the most part that would mean it's a networking problem. They also suggested that it wouldn't hurt to reinstall everything, and so I did dnf erase java-1.8.0-openjdk-1:1.8.0.111-5.b16.fc25.x86_64 java-1.8.0-openjdk-headless-1:1.8.0.111-5.b16.fc25.x86_64 then installed java and libreoffice, which it uninstalled for some reason. I deleted the .ftb folder in my home folder, as well as everything in the install folder I keep on a separate drive. So basically back to square one, start up FTB, crashes. It prints another error just like the one above, thinking that maybe the update included a java update, I downgraded my java to java-1.8.0-1:1.8.0.111-1.b16.fc25.x86_64 and headless. This also showed me that I should only do dnf update, so that I know what is happening.

Downgrading didn't help, even when I loaded up the previous Fedora from grub, so I moved on to trying to troubleshoot networking. Networking is not my strength, I know very little, but I tried. So I installed firewalld-config and used it to make a service called minecraft that used port 25565 on both the tcp and udp. Nothing changed, it still failed on the SSL if it didn't crash during load up. Checking the status of firewalld.service showed a bunch of iptable errors, so I erased and reinstalled firewalld. Now I don't see the iptable errors, but I still crash and get the SSL errors. I have even upgraded my java back to the newest one just to see if that would help, nope.

I have reached the end on my knowledge so I am here to ask for help. Also I think I got this in the right category, but if I didn't please move me, still getting used to the changes.

Port 25565 is only for connecting to game servers. The authlib download will be reaching out to port 80 or 443, though normally firewall will allow outgoing connections like this otherwise you couldn't browse the web etc.

Edit:
Can you download this file?
https://libraries.minecraft.net/com/mojang/authlib/1.5.16/authlib-1.5.16-sources.jar
It's highly unlikely that this is the correct version, but being able to download it would imply that you don't have an obvious network problem.

Ansem_of_Nexus · January 26, 2017, 10:10pm

It downloaded just fine, I don't know if it's the right one either, and I didn't know that you could download them manually either. I might look into seeing if I can just download it my self and put it in the folder it's supposed to be in, but I don't think that will fix my overall problem.

candybar · January 26, 2017, 10:13pm

I would try to use the vanilla launcher. It should also download authlib. If it works then its not likely java or network related, but something w/ FTB's launcher.

Ansem_of_Nexus · January 26, 2017, 10:33pm

... So it doesn't seem like it's just a FTB problem...
Minecraft also fails to get it's authlib.

Ansem_of_Nexus · January 27, 2017, 5:44pm

Update:
removed java, erased the security back up, updated ca-certs, and then installed java again... still crashes and gets a SSL error if it doesn't.

could the java problem be responsible for the SSL errors. Like if the part that fails and crashes java, doesn't fail completely it messes up java's ability to properly handle internet traffic related to SSL certs??

MisteryAngel · January 27, 2017, 5:56pm

Maybe java see´s the certificate as invailed, and maybe blocks it?
I dont know if Oracle Java is available in Fedora or rpm fusion repo´s.
Otherwise you might try that instead.

Dje4321 · January 27, 2017, 6:04pm

i would update java first

Ansem_of_Nexus · January 27, 2017, 7:16pm

I hate to say this but it looks like using Oracle Java is going to be my solution. I don't understand why openJDK would just suddenly stop working after an update, guess there is something that was changed in the kernel or something. I installed the 64-bit rpm off Oracle's site and everything just works perfectly now, no crashes, and no SSL failures. I guess I will give openjdk a try again after the next update, see if it gets fixed.

candybar · January 27, 2017, 9:40pm

Shame you have to fondle some oracles. Hopefully OpenJDk will get fixed up soon.

MisteryAngel · January 28, 2017, 4:53am

Well atleast glad my suggestion atleast worked.
Not sure what the issue with open JDK is.
But yeah, maybe something to investigate.

hikingpete · August 3, 2018, 5:09pm

I just ran into a similar problem after upgrading from Fedora 26 to Fedora 28 (something to do with ‘authlib’). It seems to have been related to JRE 9. I uninstalled version 9, so I only had 1.8 left, and the error went away.
