Mount error: "unknown filesystem type 'exfat'"

  • 772

When trying to mount an exfat filesystem, I get the following error:

Error mounting /dev/sda6 at /media/gkp/Backup: Command-line 
`mount -t "exfat" -o "uhelper=udisks2,nodev,nosuid" "/dev/sda6" "/media/gkp/Backup"' 
exited with non-zero exit status 32: mount: unknown filesystem type 'exfat'

Exfat is used on some USB sticks and camera sd cards. What can I do to mount this type of filesystem?

mount

  1. You get this error because the exfat filesystem is not installed in Ubuntu by default. exFAT is proprietary and patented by Microsoft.

    Ubuntu 13.10 or higher

    Since Ubuntu 13.10, this package is in the main repository. Just install exfat-fuse and exfat-utils:

    sudo apt update && sudo apt install exfat-fuse exfat-utils

    Ubuntu 12.04

    For ubuntu 13.04 and lower, you'll need a ppa to install the exfat support. Installation procedure:

    sudo apt-add-repository ppa:relan/exfat
sudo apt-get update
sudo apt-get install fuse-exfat

    If you see the error gpg: "tag:launchpad.net:2008:redacted" not a key ID: skipping during the apt-add-repository step, then you'll need to manually install the signing key and run the apt-get update and apt-get install steps after that:

    sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 4DF9B28CA252A784

  2. As of November 25, 2019, this does not work yet in Ubuntu 19.10 Eoan, probably because apt just cannot grab exfat-fuse. I fixed this problem by downloading exfat-fuse deb directly. This is after installing a dependency.
