Reading Samsung Exfat K-Ubuntu 19.10

When trying to read any exfat formatted SD card it suddenly was not recognised by my system, so I tried to upgrade from Kubuntu 18.10 to 19.10, and it didn't help. Then I found a post about that Exfat is not supported by the kernel before version 5.4, but Kubuntu 19.10 is shipped with 5.3, but the packages exfat-fuse and exfat-utils should take care of it, but they were already installed and did not work apparently. And also my kernel is 5.0.x for some reason (5.0.0-36-generic).
