I've recently noticed an issue with Ubuntu Software Center which I have tried to resolve following the answers provided in this similar question without result and this answer in particular which partially worked but didn't persist.
The Issue
After installing 20.04 I opened Ubuntu Software Center and installed a number of apps without any problem - one of which was Stacer which I will use as an example.
In Show Applications
the app is clearly present and right clicking on the icon selecting Show Details
provides the image above and it works perfectly well.
However, if I open Ubuntu Software Center and type in the search bar stacer
it reports that no application is found:
Nor is it listed when selecting the Installed
tab.
This is the setup for for Software and Updates.
There are other applications I have previously installed which are also now reported as No Application found
such as gLabels, gscan2pdf and others.
Has something changed since I initially installed 20.04.1 and more importantly, how can I restore good order to the Ubuntu Software Center?
