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). The reaseon is that at the time of writing the kernel version 5.3.x is unstable.

Error messages from dmesg |grep mmc:

[ 1023.731743] mmcblk0: error -110 requesting status
[ 1023.731751] mmcblk0: recovery failed!
[ 1023.731775] print_req_error: I/O error, dev mmcblk0, sector 0 flags 0
[ 1106.971868] print_req_error: I/O error, dev mmcblk0, sector 2 flags 0
[ 1106.971882] Buffer I/O error on dev mmcblk0, logical block 1, async page read
[ 1106.971896] mmc0: card 43c0 removed
[ 1109.090251] Buffer I/O error on dev mmcblk0, logical block 0, async page read

Then I found this post (https://www.omgubuntu.co.uk/2019/09/install-samsung-exfat-driver-ubuntu-ppa) because of the Samsung formatted Exfat stuff:
sudo add-apt-repository ppa:arter97/exfat-linux
sudo apt install exfat-dkms

But this removes exfat-fuse. After a reboot the exfat SD card is not recognised at all by dmesg or by the system even though the module is loaded (/lib/modules/5.0.0-36-generic/updates/dkms/exfat.ko
).

Back to exfat-fuse, and into Windoze to handle exfat SD card (microSD).
