My mother has an old Lenovo laptop (bought I think in 2010) with Ubuntu 16.04 installed. It was 14.04 but I upgraded it the last time I was at her place. Her laptop has become very sluggish recently and it's painful to talk over Skype and I tried Duo web and it's still slow and sound stutters and so on.
I am thinking to update her system to more recent one and probably switch her from Ubuntu to Lubuntu or something lightweight. However, she lives far away and I can now for many reasons to go to her now.
I wonder if there is a good way to upgrade her remotely. One of the problems is that she doesn't have a smartphone so if something goes wrong I won't be able to see it. So I wonder if there is a way to keep connected to her laptop to see what is going on and fix it if something breaks during the upgrade? I currently can connect to her laptop through Teamviewer.
