Thanks for bringing this to our attention! Currently our installer only supports LTS versions of ubuntu (difficult to troubleshoot problems that might cropup on intermediate versions). If you feel comfortable editing the install script, these are the relevant lines:

hnn/installer/ubuntu/hnn-ubuntu.sh

Lines 44 to 52 in 4bc3e4d

	[[ $PYTHON_VERSION ]] || {
	if [[ "$DISTRIB" =~ "xenial" ]]; then
	PYTHON_VERSION=3.5
	elif [[ "$DISTRIB" =~ "bionic" ]]; then
	PYTHON_VERSION=3.6
	elif [[ "$DISTRIB" =~ "disco" ]]; then
	PYTHON_VERSION=3.7
	elif [[ "$DISTRIB" =~ "focal" ]]; then
	PYTHON_VERSION=3.8

I believe you simply need to add this below L52, but I don't have a version of impish to test this at the moment.

elif [[ "$DISTRIB" =~ "impish" ]]; then 
     PYTHON_VERSION=3.8 

@jasmainak should we consider relaxing the LTS requirement? There aren't that many intermediate releases between xenial and focal: https://en.wikipedia.org/wiki/Ubuntu_version_history

[jasmainak]

sure.

But how about adding a few additional requirements to the setup.py here:

hnn/setup.py

Line 40 in 4bc3e4d

install_requires=['hnn-core']

? That should fix the install for a majority of cases. You'll need to add PyQt5 and nlopt
