After digging into the problem, I found that the problem is in the Python version. I was using 3.5.2, which is the latest version for Ubuntu 16.04 LTS. But it is not sufficient for building recent versions of Chromium as it seems to require at least 3.7 or above (this comment is not based on any official docs, it is just my guess.)

First check your python3 version with python3 --version . If it is the case, upgrade your Linux distro and run build/install-build-deps.sh .

Alternatively, update python3 only with the following commands:

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt install python3.9
sudo ln -sf /usr/bin/python3.9 /usr/bin/python3
