Wow. Sorry that happened. As a long time linux user I am really unhappy with the way Ubuntu has gone recently. Enough so that when I was dropping in my new video card I didn’t even consider using that distro anymore. The whole snap thing just rubbed me wrong, and on top of that I was getting a message that if I didn’t join their subscription thing, that I wouldn’t get all of the updates available. Now there were explanations that that wasn’t the actual case, but their wording just really rubbed me wrong, even if it was a ‘free’ subscription for up to five machines, etc. Back to your situation, I think it might be time to explore some other distros as they might be a better fit for you, and more of a plug and play experience for you. My suggestion would be to install a VM like Virtualbox and then download some .iso files and use them on some new virtual machines that you can run and get a basic idea of how they work/look/feel. After you find one that fits your needs you can migrate. Just remember, when people start giving you grief, just give them the old grep -v… That will make them go away.

I am confused, because you ask for it to be more plug and play, complain about using the terminal to install, and then say you gave up and installed it the plug and play way by using the Ubuntu store. It reads like you are complaining that you have to drive to another city and you aren’t getting there in time because you are pushing the car. So you eventually get in and drive the car and insist that pushing it was “the right way”…

Does the uid you are using to run nginx have permissions to read the root folder (defined above as /var/www/html/partviewer/public , not the actual linux root) and below?

Yup, people have proven time and time again that they are willing to give up privacy for something simple like convenience. So as tech progresses so will the deterioration of any privacy we may have left.
