I tried to launch Tribler from XFCE Applications menu.
Nothing showed up.
I tried to launch Tribler from terminal.
But it gave me this.
I however found this:
Every time I try to run Tribler this script starts and then terminates.
Every time I try to run Tribler this script starts and then terminates.
I have the same issue with Tribler 7.3.0 on Debian, everytime I start it, the loading screen shows up, and then it terminates.
I found this in ~/.Tribler/tribler-gui-error.log:

freeglut3 is already the newest version (2.8.1-3).
python-opengl is already the newest version (3.1.0+dfsg-1).
python-pyqtgraph is already the newest version (0.10.0-1).
python-qt4 is already the newest version (4.11.4+dfsg-2+b1).
libqtassistantclient4 is already the newest version (4.6.3-7+b1).
Both the pip ones are also installed:
# pip install lz4
Requirement already satisfied: lz4 in /usr/local/lib/python2.7/dist-packages
Requirement already satisfied: future in /usr/local/lib/python2.7/dist-packages (from lz4)
# pip install pony
Requirement already satisfied: pony in /usr/local/lib/python2.7/dist-packages
Checked the python-cryptography as well:
# apt-get install python-cryptography
python-cryptography is already the newest version (1.7.1-3+deb9u1).
Still get the “60 second” error.
Ai, we thought we fixed that one… Sorry
Could you please dive into the /tmp/ something log file that Tribler creates?
It contains which dependencies on Linux are not found (e.g. pip/apt stuff, or --user mixup). Seems we missed something that results in eternal loading of the GUI

Thank you for that helpful insight.
Shoot, another crypto lib problem. Debian people being very pure about the patents, export regulations, not exposing AEAD to Python, and/or something. Guess we need to ship our own custom package/wrapper for crypto. Something we really don’t want, but forced to do.
@S.Pan-TUDelft Is this also happening on latest Debian?
@shaunot It seems like cryptography package is not latest. We require >=2.3.
#apt-get install python-cryptography
python-cryptography is already the newest version (1.7.1-3+deb9u1).
1.7.1-3 is not the latest version of cryptography. We’ll
Could you try installing aead package using pip?
pip install --user aead
@root it should be working fine on Debian 10
Just a “user confirmation”, that this worked for me on Deb9.
I checked for those pkgs, and found that 2 weren’t installed…
I Installed the following packages:
freeglut3 (2.8.1-3)
python-opengl (3.1.0+dfsg-1)
followed by @S.Pan-TUDelft Sandip’s :
pip install --user aead
I may have rebooted(?) and clicked tribler from menu and it ran!!
Thanks to ALL…for this post!
I ended up upgrading the VM to Buster (Debian 10.1) and it is now working.
