I'm getting the error unknown filesystem type 'exfat' and have seen all the posts and articles that reference installing exfat-utils and exfat-fuse. However, exfat-utils is not available under 22.04 LTS. I found exfat-progs and tried that but it still gives the error when attempting to mount an exFat formatted partition.
An attempt to locate exfat-utils confirms it is not in jammy repos:
