Installation on Ubuntu 20.04 and Linux Mint 20.1

[mondele]

After considerable experimentation (in a docker instance, to protect my machine) I got doc-browser to compile after:

sudo apt install qt5-default qtwebengine5-dev qml-module-qtlocation qml-module-qtwebengine liblzma-dev libghc-regex-pcre-dev pkg-config curl
curl -sSL https://get.haskellstack.org | sh
echo "PATH=~/.local/bin/:\$PATH" >> ~/.bashrc
. ~/.bashrc
stack install c2hs alex happy hsqml
stack install

(I did, actually, have curl installed before, but I added it for clarity.)

However, when I run doc-browser, I get an error:

$ doc-browser
