Missing dependencies for ubuntu 20.04

[sharksforarms]

I had to do the following to get to a working state (mostly due to pip dependency build errors)

sudo apt install libcairo2-dev libjpeg-dev libgif-dev
sudo apt install libgirepository1.0-dev
sudo apt install libcups2-dev
sudo apt install xvfb
pip3 install xvfbwrapper

I also needed to add --xvfb in agent.sh to make sure xprop wasn't getting called, or else I would hit this error: catchpoint/WebPageTest.agent#458

I currently have an error:

12:53:52.798 - Default interface: venet0
RTNETLINK answers: File exists
Error: Exclusivity flag on, cannot modify.
Error: Cannot delete qdisc with handle of zero.

Command:
sudo /usr/bin/python3 /home/agent/wptagent-master/wptagent.py --server "https://domain.com/work/" --location "Test" -vvvv --dockerized --xvbf

Does it give a backtrace or any more information? Does it run?

Operating system Debian 11 and not running. What other information would you need?

I am too facing the same issue, @sharksforarms as you mentioned also needed to add --xvfb in agent.sh can you guide me where to do that.

I am using ubuntu 24.04

It's when calling /wptagent/wptagent.py

Note: This is what I did 3 years ago, unsure if it's still relevant
