How Long "Should" It Take

[Grizzly]

Hi All

I have been "Trying" to install 20.04.2 over my old 16.04.5 (on a dual boot 
with Win7)

Dell Inspiron, E5300 2.6Ghz Duel Core, 4Gb Ram, Intel i915 Display

Normal try before install option hung for an hour (well did nothing past a 
purple screen with a black curser)

Safe Graphics try before install seemed to work

F6 then
Normal install option hung (again well did nothing past a purple screen with a 
black curser)

F6
Safe Graphics install got started, took just over an hour from the choice of 
what to install (Minimal install & Thrid party drivers) to get to the choice to 
"Erase 16.04.5 and instal 20.04.2" over it

We are now about 3 hours on and I still only have the spining circle thing, no 
sign of any movment along the install route

should I wait even longer?

does 20.04.2 take a long time ?
