It seems none of the so-called software "stores" are really doing a good job of serving their "customers". The software store is seen by the big companies as another cash cow that can become a revenue stream for them with little effort or support put back into it. When that doesn't work out as they had planned, they abandon it.
Yeah unfortunately, I am also sometimes get tired of searching the apt install package name on google.
The Ubuntu Software Center is rubbish, just use Synaptic Package Manager. Code: sudo apt-get install -y synaptic gdebi Or if you must have point and click, try Muon Discover.
