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?

Please provide the version of Ubuntu you are using. As you can see there is more than 1 answer for Ubuntu. – Rinzwind Oct 23 '13 at 10:26

You get this error because the exfat filesystem is not installed in Ubuntu by default.

Ubuntu 14.04 or higher.

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

sudo apt-get 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: "" 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 --recv-keys 4DF9B28CA252A784

looks like for 13.10 you don't even need the ppa it's just sudo apt-get install exfat-fuse ref: – rogerdpack Jan 6 '14 at 14:48
I followed same, after doing all steps at last it saying "FUSE exfat 1.0.1 ERROR: failed to open `/dev/sdd1'." any suggestion? – Shubh Apr 3 '14 at 10:44
:) and after then sudo ntfsfix /dev/sdb1 help me to get mount. wait for few second it could time to mount. – Shubh Apr 3 '14 at 10:51
+1. On Ubuntu 14.04, no PPA is needed. I was able to sudo apt-get install exfat-fuse and, after installation, my 64GB SD CARD mounted as soon as I plugged it in. – Drew Noakes Jun 11 '14 at 18:38
It works in Ubuntu 15.10 too! – Luis Lobo Borobia Feb 2 at 21:44

This solution worked for me, as I had all my backup files on the SD card. I used:

sudo apt-get install exfat-fuse exfat-utils

On Ubuntu 15.10.
