I downloaded image and installed Ubuntu MATE 20.04 weeks ago but due to error pop-up, I re-downloaded the image and re-installed Ubuntu MATE 20.04 from below link. But, this time, I found the Ubuntu MATE Welcome and Software Boutique are not included.
Can anyone give me device how to install manually? And, any other Software Center is recommended to install?
