Installing Lektor using $ curl -sf https://www.getlektor.com/installer.py | sudo python3 as per documentation results in an error. How can I fix this please?

Same here, on AVL-MXE-2020.12.03 (Debian-Buster based). I solved it by adding a line in installer.py to upgrade pip before installing lektor:

def install_lektor(lib_dir):
    create_virtualenv(lib_dir)

    pip = get_pip(lib_dir)
    call([pip, "install", "--upgrade", "pip"])

@oliverbienert I finally got round to trying your suggestion on Elementary OS 5.1.7, it works! Thank you so much! I will add your fix as a pull request on the lektor/lektor-website repo. P.S. I also asked the question on Stack Overflow. https://stackoverflow.com/questions/66731157/lektor-cms-installation-fails-on-elementary-os-5-1-7-hera. I’ll leave it to you @oliverbienert to add the official answer there if you like 😃
