I have recently changed my Operating System from windows 11 to Ubuntu 20.04. I have transferred the data from my old system. The problem is that Ubuntu is recognising PDF files as images and opening in photo viewer. I have tried by downloading files from the internet too. Even the downloaded files are recognised as images.
When I open the properties of the file its showing like this.
This is the icon shown.
The type is shown as Image in file explorer.
This is how its shown in file explorer
Edit : Now I have upgraded to 22.04.Still the problem exists.What should I do?
