I just upgraded to a new installed Fedora 26, taking the launcher with me. When starting it the original way, I am getting the following error:
Quote:
This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, xcb.

Reinstalling the application may fix this problem.
Aborted


Reading around in the forum, it seems like using the shell script shall fix this for most people. However, when doing this, the launcher just starts and going into wait for some reason:

It seems never to return from this. Any idea, what this might be?

Hello!

So the xcb bit was the only relevant error the rest is debug info with no actual errors in it. The xcb error means the launcher can't find the Qt5 libs. Probably when you updated fedora either the symlink to xcb/qt libs was removed or the libs themselves were.

Reinstalling the 32bit compatibility for your video drivers with out using the distro specific package you normally use will fix this (until the next system mesa update) so if that gets you working check /usr/lib/i386-linux-gnu/ and ldconfig -p | grep Qt before and after so you can compare and figure out which symlink you were missing. Or just install qt5 for i386 arch, if they are gone. Remember when installing you need the i386 qt libs even tho your system is 64 bit and you need the opengl 32 bit compatibility libs for your video too... Was that redundant? Yes... yes it was.

Try that and if it doesn't work post your errors from .local/share/CCP/EVE/Launcher/launcher*.txt as that's going to have the most useful info.

Good luck!

Its a fresh installation, not a upgrade. So I think it is more likely that some package might be missing than actually some symbolic link might be wrong. I am also pretty sure that the GPU drivers and libs are setup correctly as other stuff is working fine. My best guess is that it is related to QT as the only other issue I found so far is by Albion Online that is also using a qt launcher that is freezing.

I installed all possible qt5 libs so far as well.

The point to the log file was nice, I wasn't aware that it exist. Nothing suspicious in there either than these lines at the end:

Ahh so those SSL errors are a common issue after launcher updates. There are supposed to be symlinks in your evelauncher directory pointing to older ssl libs your system maybe doesnt have by default...

I got them manually as you see below, but apparently libssl1.0.2 is compatible if you can find it in your package manager use that then link their location under /usr/lib to ~/evelauncher w/ out the version numbers.

cd ~/eveluancher
wget http://ftp.us.debian.org/debian/pool/main/o/openssl/libssl1.0.0_1.0.1t-1+deb8u6_amd64.deb
dpkg --fsys-tarfile libssl1.0.0_1.0.1t-1+deb8u6_amd64.deb | tar xOf - ./usr/lib/x86_64-linux-gnu/libssl.so.1.0.0 > libssl.so
dpkg --fsys-tarfile libssl1.0.0_1.0.1t-1+deb8u6_amd64.deb | tar xOf - ./usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0 > libcrypto.so
rm libssl1.0.0_1.0.1t-1+deb8u6_amd64.deb
cp libssl.so ~/; cp libcrypto.so ~/;

A fellow on the forums gave us a handy script for creating the symlinks:

#!/bin/bash

CRYPTLIB="/usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0"
SSLLIB="/usr/lib/x86_64-linux-gnu/libssl.so.1.0.0"
# Change the paths to wherever you have installed evelauncher
EVECRYPT="/home/user/evelauncher/libcrypt.so"
EVESSL="/home/user/evelauncher/libssl.so"

# Check if libcrypt.so exist in evelauncher directory, if not create it.
if [ ! -f "$EVECRYPT" ] ; then
ln -s "$CRYPTLIB" "$EVECRYPT"
fi

# Check if libssl.so exist in evelauncher directory, if not create it.
if [ ! -f "$EVESSL" ] ; then
ln -s "$SSLLIB" "$EVESSL"
fi

# EOF


Good Luck
