Unable to run EAGLE 9.5.1 on Ubuntu 18.04

I'm on Ubuntu 18.04. I'm trying to install EAGLE as instructed here. I've downloaded and unzipped the package and placed it in my home directory.

In the eagle folder, I run ./eagle run and got the following error:

$ ./eagle run
Warning: QT_DEVICE_PIXEL_RATIO is deprecated. Instead use:
   QT_AUTO_SCREEN_SCALE_FACTOR to enable platform plugin controlled per-screen factors.
   QT_SCREEN_SCALE_FACTORS to set per-screen factors.
   QT_SCALE_FACTOR to set the application global scale factor.
./eagle: symbol lookup error: /usr/lib/x86_64-linux-gnu/libGLX_mesa.so.0: undefined symbol: xcb_dri3_get_supported_modifiers

I tried running sudo ./eagle run and got this instead:

$ sudo ./eagle run
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
./eagle: symbol lookup error: /usr/lib/x86_64-linux-gnu/libGLX_mesa.so.0: undefined symbol: xcb_dri3_get_supported_modifiers

Using sudo wasn't mentioned in the instructions, but I tried it anyway. I'm not sure how I should deal with those 2 errors. How should I fix this to run EAGLE?

Update 1:

I tried running the following:

~$ dpkg -S /usr/lib/x86_64-linux-gnu/libGLX_mesa.so
dpkg-query: no path found matching pattern /usr/lib/x86_64-linux-gnu/libGLX_mesa.so

~$ apt-cache policy $(dpkg -S /usr/lib/x86_64-linux-gnu/libGLX_mesa.so.0 | awk -F ":" '{print $1}')

Update 2:

I ran some more commands:

~$ ldd Eagle | grep local
ldd: ./Eagle: not regular file

Per the README

-- Linux Graphics Driver Issues Nouveau (Open Source driver for nVidia cards) may cause sporadic crashes during the login procedure.

Enable software rendering in libGL by setting LIBGL_ALWAYS_SOFTWARE to 1.

export LIBGL_ALWAYS_SOFTWARE=1 ./eagle

I ran

$: export LIBGL_ALWAYS_SOFTWARE=1

then ran the executable and it worked
