I'm not sure about this fix. I think we'd have to do this a little different since what this patch does is essentially what checkFlatpak() and checkDistro() do already.

However, this also means that both being false is essentially what this block is supposed to cover:

loganalyzer/checks/linux.py

Lines 187 to 190 in 79f7adf

	else:
	# I have never seen this, but you never know
	linuxDistroOrFlatpak = 'Distribution: ⚠️ None'
	linuxSystemInfoHelp = 'No distribution detected. This can lead to undefined behaviour. Please consult your distribution\'s support channels on how to fix this.<br>'

Which consequently would never be reached.

I think we'll have to check for Windows/Mac instead and return early.

I'll try whipping something up and opening an alternate PR and then we can decide.
